New Intake or Just A Bunch of HOT Air?….You Decide

[Homeboy981]

I have talked to a few members in DFW about this and what they have done to get MORE AIR THROUGH THEIR INTAKES! Most of it is really $%^& expensive!

Here is a ROUGH sketch of an idea for an INEXPENSIVE Cold Air Intake system. You guys would know better, so let's hear it.

Open to ideas, trying to accomplish the following:
1). Keep it reasonably priced. I like Pedro's designs but wanted it to look more presentable, no offense Pedro - I like MOST ALL your other solutions.
2). Dump as much air through the MAF as it will take, without re-programming. How much is that BTW?
3). Get rid of restrictions, unnecessary twists and turns…in the factory design.
4). Utilize a K&N Cone-Shaped Filter where the base of the SNORKEL used to be - in the COLDER AIR! I know it will work since I have "rough fit" the one from my truck. The only problem seems to be tubing related.
5). Re-use the Factory Airbox's MAF tubing section AND Firewall seal section (will need to be widened from 'Snorkel size').

Put some of these "engineering minds" around here to work, but please speak English and BE GENTLE. After all, I have not seen too many other members that have something workable…I KNOW YOU ARE OUT THERE - So Ring in and help a Poor P-car owner out!

You will be hard pressed to find them this way............

i assume, your biggest challenge will be to isolate the air filter it self, from the engine compartment.
the aftermarket products are offering some kind of metal buffer that acts as the air box.
common sense tells me, that the air inside that box, will be hotter then the OEM plastic box.
best solution IMHO, will be to fabricate some kind of a fiber glass box with multiply layers and isolation material.
not an easy job, especially when a lot of people (just like JFP) say it will result without significant results (if at all) in performance.
on another hand we have this thread:

also check out this tread, and have a look at post # 127, might give you some ideas.

The aftermarket intakes come with a plastic shield/box .

My bad.
Looks like folded metal sheet in the pictures.
Would have been nice if someone will dyno test it before and after ( like iwith the deshnork mod). Do you have one on your car JD?
If yes, what is your impression?

I have the Evolution Motor Sports intake on my vehicle. And, to answer your question, yes I've dynoed my vehicle after the intake was installed. However, this coincided with the installation of a few other mods at the same. So, it's difficult to estimate just exactly what hp gains can be attributed to the intake. My guess is that the actual gains are minimal. Maybe 3 to 5 hp if any. But, the sound it produces is just ripping ! I guess that alone made it worth while.

Forgot to attach the link in previus post.
That's the one. Look at post 127.

Google cayman cold air intake. There is a product out that mounts an oval cone filter in the fender- very easy to fab yourself.

Wouldn't it be great to have an air filter that was serviceable from the side intake vent instead of the whole process of putting the top in service mode, pulling the top forward, removing the carpet piece, removing the engine cover, opening up the stoopid airbox design, removing the old filter element, dropping a bunch of leaves sticks and crap down into the clean side, vacuuming out the airbox, replacing the element, reverse assembly procedure...

After racing motorcycles for many years and servicing the air filter between races I came to enjoy a quick airbox element removal. I would love that on my Boxster.

The fly in the ointment: Water ingestion IMO. Our air intake is in a fairly vulnerable spot and I think a lot of the airbox and snorkel design was to prevent water ingestion and foreign debris from entering the intake. Eliminating the stock airbox and snorkel will surely improve airflow to some extent but it may put the motor at risk if some big 4x4 blasts through a rain swollen puddle and nails the left side of our car. Continuous dousing while traveling next to another car on the hwy may also be a problem. We need Randall to test this the next time he gets a good ol' Texas flood.

For those of you wondering what the stock air setup in our cars are like:


What Homeboy proposed certainly has merit, and some people already have a set up like he proposed. I would be surprised if you didn't manage to free some horsepower. Personally I would love to hear the growl of the castrated engine with such a set up!
