So I know most CAI will pull hot air from the engine compartment while factory boxes will actually draw in cold air. But I was thinking of doing the battery/intake swap then cutting the filter into the fender like ford did on my f150. I know that area is very small but I have access to tools to modify the area to make it work. It is also enclosed from most water spray so that shouldn't be a problem. Only problem I see is how hard it would be to change the filter. Has anybody tried this or have any thoughts or comments on it?

 

I did this ,draw cold air from two feeds from outside the engine bay.
Drilled a 5'' hole at the side for a feed from the wheel well, & a 3'' hole at the bottom,feeds from behind the front bumper.
I use a reverse cone K&N filter & made a box with removable top from aluminum.

 

That's pretty much what I had in my mind. Do you have any pictures of it completed.

 

The air filter front,the tapered end ,sticks out of the hole a few inches & I have a slash guard on the rear ward sidefor water off the tire.
I'll get a photo of that!

 

Here's the view from under the fender,the splash guard is 1/3 round,open @ the front.

 

That engine is clean. But that is just what I was thinking. Did you notice any more throttle response/gas mileage. Also do you pass smog?

 

Thanks, & yes it goes though smog test with no problems.
This is no a stock engine ,it's a LC stage 1 Pro Street EFI !
Lots of power & gas mileage is 26-28 with driving 70 & above,if I cruise @ 65 she'll get 31.
