Signature Motoring performance intake.
I just got the Signature Motoring performance intake for my 1988 325i. HIGHLY recommended. I did about 120 miles today from Long Beach to Sun City, CA. today. Engine howls at high RPMs with noticeable power increase and acceleration. Only downside is they took about a week to ship due to adaptor being out of stock, but well worth the wait. Best $160 I've put into the car so far, and I've put in quite a bit. LOL.
Re: Signature Motoring performance intake.
Thanks dude. I had a crappy foam cone filter, no heat shield for a while now. I would have just put the stock box back in but don't have it anymore. I didn't even know someone made performance intake kits for our trust E30s! Called up Signature Motoring and they set me up, took filter and heat shield, didn't need the adaptor as the one I had before works - 2 5/8" opening.
