Anyone got any recommendations on a good cold air intake. I want to gain the best performance. Most HP & Torque gain. I read about aFe giving 20HP. Is that true?
i have the afe one in my car, it really just makes a slightly cooler sound. I think it helped once i put my exhaust in and next im doing software and headers but i do not think CAI alone will do much that you are going to notice
that bmw perfor. is really expensive... i have the BMC sport filter replacement to the original. Better sound and the car breathe better. No HP gain, maybe..
If you want real benefits then I would still go with a TRUE cold air. As in dinan or off brand or homemade. Im selling an off brand which is basically a homemade. If you are interested pm me.
^this. The factory intake is a pipe running from just above the radiator to the air box. It doesn't pull in much air from the engine bay, most comes from the inlet at the front of the car. It's a ram air intake system if you will.
Intakes make no noticable performance difference on a 325, I did it for the sound. If you replaced the restrictive stock cats with a header, well, that might be a different story.
Please let us know if you have any questions! Feel free to shoot me a PM or email.
Best,
Joe
