I think you could do it by routing a pipe with two offsets and then cutting a 4" hole around the existing small oval opening existing in the fender next to the 4" hole that is blocked by the PCM box.
.....or you could simply relocate the PCM to the position where I currently have my filter, then you would need one sweeping curve right into the hole, allowing for engine flex with a flexible connection or two. There is a bracket inside the fender that would have to be disconnected and bent over to make room for the filter.

I agree even though I have a FWI on my GP. Bends are bad to be sure. The trick is to smooth out the bends and try to do them in a sweeping ark. Keep the hole diameter as close to what it is when its straight, but you'll have some bend as it is. You have to ballance the bends against cooler air which is what the Fenderwell intake is geared to do. I use the flex tube sold by Intense racing coupled to the plastic 45% bend sold by Parts for Your Car.com. My filter is a 7 inch *&B open end cone.The intake added maybe 5 to 7 crank HP.

Wouldn't a CAI add the same power as a FWI? 5 to 10 HP depending on the application?

Since there are so many CAI'* available for us, why not just go with that?


Just IMO.

Sometimes it depends on where you live. Here in Texas where it stays so hot almost all the time, the Fenderwell makes sense because you are further away from the engine bay. A CAI has advantages, but I didn't like the idea of still being behind that hot headlight. If I could have hooked up a snorkle I would have. I should also say I like to build my own stuff If I can.

My goal is to change the design of my CAI one more time to seal it up a little better. Then punch a hole down or route a hose behind the headlight to ram-air feed the box. This will just positive-pressure the box, then the cone can pull in what it wants.

If the box always has positive pressure of outside air, it can't pull in hot air from the engine bay.

Now that sounds good. I didn't think of that!

I never would have thought someone would put a 90* bend in an intake pipe.

I can't wait to figure out my CAI.
