Steiger Performance 3.3/3.8L V6 Minivan Air Intake
(For Chrysler/Dodge/Plymouth Minivans)


Note: I hope the information on this page will be helpful to you, and will give you an idea of what this intake is all about. I apologize in advance for its "long-windedness". :-) I have tried to anticipate the various questions someone might ask about it, and have set up the page in a question/answer format. I have done my best to shed some light on this product from as unbiased a viewpoint as possible.

Pictured on this page are the components included in the kit. The intake consists of a genuine K&N air filter and a 16 gauge mandrel bent 3" intake tube which has been powdercoated inside and out and plumbed with PCV and temperature sensor fittings. Also included is a silicone connector, high torque stainless steel hose clamps, a zip tie for the PCV hose and illustrated install instructions.

Why should I install an aftermarket intake on my minivan?

Essentially, for more power, improved gas mileage and better throttle response. What this intake system does is to replace the restrictive paper filter with a K&N "conical" air filter and replace the restrictive stock airbox and flex coupling with a mandrel bent 3" tube. This makes it easier for the engine to draw in the air that it needs for combustion, and allows the engine to draw in more air than before. By drawing in more air, the engine can use more fuel, and greater power is the result.

This may not seem like a formula for better gas mileage, but the additional horsepower means the engine doesn't have to work as hard to do the same work, which will result in better gas mileage. This may seem like a strange concept at first, but it is true - a more powerful engine is often more fuel efficient than a less powerful one simply because it doesn't have to work as hard to do the same work. It is for this reason that the 3.9L V6 Dakotas and Rams quite often get about the same gas mileage as a 5.2L or 5.9L equipped vehicle. The smaller motor must rev longer and higher to accomplish the same task. This becomes especially evident while towing. A good example based on personal experience is a comparison between my 5.2L V8 Dakota and my family's 3.8L V6 minivan. For everyday driving, they both get around 17-18mpg. While towing a 6,000lb car trailer back from Carlisle, I averaged 13mpg in the V8 Dakota. We went on a family vacation in the minivan towing a 2,000lb motorcycle trailer, and got 11mpg. The V6 got 2mpg less than the V8 while towing, and that was with 1/3 the load! Proof positive that more power can indeed translate into better gas mileage.

This assumes of course, that you can keep your foot out of it. :-) More power does actually require more fuel, so if you drove around with your foot to the floor all the time, then installed an intake, and continued to drive around with your foot to the floor, you will get less gas mileage than before, because you have more power than before, and you are using all of those horsies - you are burning more fuel. However, if you drive like this, I suspect that gas mileage is not your primary concern anyway. :-)

Performance Impressions:

I do not have any quarter mile times or dyno numbers to be able to give you exact HP or ET changes, but here is what we noticed after installing this intake:

Why should I buy a Steiger Performance intake?

Ok, so we've covered the general benefits of adding an aftermarket air intake, now comes the part where I describe this particular intake to help you decide whether you would prefer to buy mine or somebody else's... (Actually, as far as I know, there isn't anybody else who makes an intake for Mopar minivans. This makes me either incredibly innovative or incredibly insane.) :-)

After developing an intake for the 4.7L Dakotas and Durangos, I realized I had all the building blocks to design an intake for many other vehicles. Readily available prototyping vehicles available to me were a Chrysler Town & Country and PT Cruiser. The PT Cruiser is a fairly popular vehicle and others seem to have that market pretty well covered, so my attention turned to the minivan. It struck me that there doesn't seem to be much of a market for aftermarket goodies for minivans, but I figured there may be enough interested folks out there to make it worth my while. Given the relatively low initial investment to develop an intake, I decided to go ahead and do it.

My intake consists of a mandrel bent 16 gauge steel tube which I powdercoat inside and out. The tube has provisions for both the PCV (Positive Crankcase Ventilation) tube and the intake temperature sensor; the stock items just connect directly to the intake the same way they were connected to the stock intake system. A plastic zip tie ensures that the PCV hose won't interfere with the throttle linkage. A silicone connector attaches the intake to the engine's throttle body with a pair of high torque stainless steel hose clamps. The filter is a K&N, which has been pre-oiled at the factory and comes with their 1 million mile warranty. This is all excellent quality stuff. Because I personally build each intake by hand, I can powdercoat the tube many different colors. Now, I'm not saying that it'll exactly match your paint, but there is probably a powder available which is close. Or, if you prefer, it can be done in a contrasting color. There are also other things that can be done like wild custom colors such as metallics, flourescents, translucents, iridescents, textures, prism effects, etc. I have a set of "standard" colors which I keep in stock and which are included in the price of the intake. However, there are many other colors and options available for an additional fee. To get an idea of what is available, check out, (a popular powdercoating site) and click on "Powders" or "Colors". Click here for more powdercoat info and pricing details.

My main goal with these intakes was to create a simple, quality intake with a reasonable price tag. That's definitely not an easy task as quality and low price do not usually go hand in hand, and I can't take advantage of economies of scale due to the low volumes involved. As a fellow hot rodder, I'm always looking for the best value for my money, and that's the mindset I use when creating my products. To be completely honest with you, the prices came out a bit higher than where I was hoping, but there's nothing I can do about that without compromising on quality; a path I am not willing to take. However, I have decided to offer these intakes in several different ways which, depending on your circumstances, might save you some money:

Intake kit
This is the normal intake kit, as described elsewhere on this page - it comes with illustrated install instructions, the K&N filter, the tube is powdercoated and plumbed for the PCV valve & temp sensor, etc. Basically, you pull it out of the box and bolt it on.
Intake kit, minus filter
This is exactly the same as above, but the K&N filter is not included. I offer this option in case you have a cheap source of K&N filters, or have a Summit gift certificate, etc. You may be able to save a few bucks.
Intake kit, minus powdercoat
This is the full intake kit, except that the tube is sent to you "raw"; it will be bare metal and you will be responsible for applying a finish to it. Perhaps you want to spray paint it with one of those fancy color shifting paints, or maybe you would like to have it chromed, or gold plated, who knows? :-) At any rate, this will save you the powdercoating charges. Note that because the tube will be bare metal, you should apply some sort of finish to it before using it, otherwise it will be susceptible to rust and corrosion. When the intake is shipped to you, the tube will be protected with a light oil and sealed in a plastic bag to prevent rust, but once you open it up and clean it off, be aware that you should apply a finish fairly soon.
Intake kit, minus filter, minus powdercoat
Fairly self explanatory :-) This is the intake kit, but without the filter and without the powdercoat.

What filter comes with your intake? Is it big enough for my engine?

The intake comes with a K&N RE-0910. Here are the vital statistics for this filter:

Base Diameter5"
Top Diameter 4 5/8"
Length 8"
Effective filtering area 109.6 sq. in.
Theoretical max displacement 456.8 (7.5L)

The 3.8L has a horsepower peak of around 5000 RPM, and therefore requires approximately 55.66sq. in. of filtering area. The "theoretical max displacement" figures in the table above refer to the size engine this filter would be able to support, given the same ~5000 RPM HP peak. As you can see, the filter is more than adequate. With 197% of the required filtering area, it is twice as big as it needs to be. What this means is that it will easily handle your engine's air requirements, and will also allow you to go a very long time before you will need to clean the filter. (Unlike conventional paper filters, K&N filters can be cleaned and re-oiled; you don't have to replace them when they get dirty. K&N sells a "recharge" kit which you can pick up just about anywhere for about $10 which allows you to clean and re-oil your filter several times.)

How hard is the install? Is it reversable?

This intake is extremely simple to install, and takes only common hand tools. (You can get by with nothing more than a wrench and a screwdriver.) There is no cutting or trimming involved, so besides removing the stock airbox and flex hose, nothing is modified on the vehicle or the engine itself. What this means is that the intake is 100% bolt-on, and that you can put the engine exactly back to stock at any time. To install (or un-install) my intake will probably take you no more than 10 minutes or so. Probably much less, after you've done it a couple of times. :-)

For details about what exactly is involved to install this intake, check out the full color install instructions in Adobe PDF format.

Is your intake emissions legal?

That depends. :-) The requirements are different from state to state, and many times even from city to city. My intake does not carry a CARB EO number, so you will need to check with whomever you use to inspect your vehicles to see if they will pass it with an aftermarket intake installed.

Will your intake void my warranty?

No. Federal requirements say that the only way the dealer can void your warranty due to the addition of an aftermarket part is if they can prove that the part caused the problem in question. For a great deal of information regarding warranty issues as they relate to aftermarket parts, check out SEMA's consumer web site at You shouldn't have a problem getting warranty coverage with my intake installed, but lets face it, there are some bad dealerships out there with employees that are either ignorant of the law, or assume that a consumer won't press the issue. If this is an issue you are very concerned about, it would only take a few minutes to swap your stock intake back in before going to the dealer, and nobody would be the wiser. (The "what they don't know won't hurt them" theory...) :-) Please understand - I am not suggesting this as a way to "cheat" the dealership into providing you warranty service. The fact of the matter is that the dealership must honor your warranty unless they can prove that an aftermarket part was the cause of your problem. But, due to the attitudes of some service departments, it is sometimes easier to just avoid the potential problem altogether. Due to the bolt-on nature of my intake, this is an option that is available to you.

Which vehicles will this intake fit?

The prototyping for this kit was done on a 2002 Chrysler Town & Country with a 3.8L V6. I am not certain what differences there might be from model year to year. This intake will probably fit many different years, but without knowing for sure, all I can tell you is that it has been tested to work with the following engines and years so far:

Feel free to take a look at the on-line install instructions; that may be enough to allow you to determine whether this intake will work on your vehicle or not. If you do order one and discover that it doesn't work, just let me know and I would be happy to refund your purchase price (less shipping) if you can return it in re-saleable condition.

I am definitely interested in finding out what other years this intake might fit. I will generally offer a discount to anyone willing to try an intake on a vehicle which I don't have data for, check out the Beta Testing and Prototyping section of my web site to see if your vehicle might qualify, and/or drop me an e-mail.

How long will it take to ship my intake once I order?

Please allow a couple of weeks for your intake to be delivered. I am a small outfit, so I can't very well have a huge stockpile of intakes on hand; especially given the different colors available. :-) Each is built to order, and if I need to order a special powder or something, that's obviously going to take longer than usual. I will make every effort to get your intake to you as quickly as possible (with the exception of sacrificing build quality, of course). Once I have all the required materials, it takes about a day to build your intake. So, the actual time required could range from a few days to a couple of weeks.
