I have found that the most effective intakes are the ones with the least amount of turbulance. I have my own intake in the car right now. It is a single side with a custom mount for the maf. I had to extend the wire for the maf as it is relocated. Its not very loud at normal driving, but wot it lets you know there is something under the hood. The car feels like it stays in the sweet spot much longer and on the highway at any speed you have that sudden burst of speed. I dont have dyno#s and dont really care because Im not going to sell any but I had fun with the fab and the end result. My car is a lease so I am hesitant to mess with it but the 3.2 has the potential its a quition of time and money.
