what would be the easiest and cheapest way to make my own good quality cold air intake using parts and filters that i can buy from advanced auto parts of autozone?
Here you go...
Just built one myself this week. Here is my write up with pics on Bimmerforums. http://forums.bimmerforums.com/forum/showt...5&highlight=cai
Would have cost me $82.00 if I would of had to buy the aluminum tubing from JC Whitney.
The harded parts for you to find will be the aluminum tubing and the 3" hose. Most regular autoparts stores do not carry these items, or the KN cone filter for that matter.
I got the KN 8" cone filter part number RE-0910 at a performance shop. (PepBoys, Autozone, Napa didnt carry them)
I got the 3" hose and hose clamps at Napa. They happened to carry this hose which is a coolant hose for an 18 wheeler.
The aluminum tubing I got for free off a guy who totalled his 325i.
I would suggest calling different places before you start driving around. I would be very suprised if you could get all the parts you need at one place.
