K&N 57-Series Cold Air Intake

Comparison between stock and new cold air intake on a 2005 BMW 330xi. Revving sounds funny because I did a cold start in the morning.

Cold Air Intake with Blow Off Valve - Sound Test
CPE CAI - Homemade DIY Cold Air Intake with Blow Off Valve - Mazda cx7 -Sound Test Engine light is on for stuck EGR valve. fixed using seafoam. Melted out the stock MAF socket with a soldering iron. Purchased K&N air filter and placed it on the end of the tube. just that easy. This is a Mazda cx7 GT 2.3 L MZR turbocharged I4 with 244 bhp and has an internal blow off valve to regulate engine psi. The blow off valve sound is hidden while using the stock setup. After the modification the internal blow off valve can be heard. PriorToImpact Prior To Impact

K&N 77 Series Performance Cold Air Intake system on Silverado
A before and after look at a new K&N 77 series intake system on a 2000 Chevrolet 1500 4.8L V8. If you are looking to buy this for your truck, I recommend it 100%. Increased gas millage and increased horsepower (both noticeably different). Wish I would have purchased it earlier. sorry for the poor sound quality. (and i will never rev my engine again.)
