Custom CAI for 97 GA
The Right Formula
03-02-2004, 06:00 PM
Working on building a custom cold air intake to make my engine breath a bit easier and need a bit of advice.
I plan to get rid of the airbox all together and go with a more direct intake. I have it all mapped out except for a suitable filter. I'm going to use a smooth hose between the MAF and throttle body and use a 3"x3" fernco coming off the MAF and use a filter attatched to that. However, I'm at a loss on how to build a filter and get on there. Was thinking a few heads would be better than one.
And if I can swing it (still mapping it out in my mind) I'd do a bit of plumbing under the hood and arrange it so it's a true CAI and have another hose coming off the filter and going lower into the bay--maybe behind the radiator to pick up some fresh O2.
Any ideas?

Its easy and cheap to do yourself. Pcv pipe or aluminum pipe works the same structural wise. pvc is cheaper and more heat resistant , aluminum is lighter and looks cooler. I use a Oil Dressed air filter , the element is enclosed in a f-150 air filter box using the same size filter and cut off the rear of the box just enough to fit the filter lock ring on.
I needed a tube to fit to the filter cus it was just a big hole , i used a 4" to 3" rubber pvc joint and fused it in the filter element. the 3" portion sticks out and connects to the MAS and is conected by a short pvc pipe to the throttle body. on the lower front side of the filter box i put a 4'' hole in and connected a 4'' pipe that leads to a y through the front fender the y splits off to each fog light port and is my make shift ram air setup. the end of the filter box is open to the fender through a hole , i plug it when goin out to the highway for a sealed ram air box.
Its pretty easy to do , just use your imagination , by the way my set up costed me 120 dollars cnd.
