Review on Spectre Engine Air Filter: High Performance, Premium, Washable, Replacement Filter: Fits 1991-2007 CHEVROLET, GMC, ISUZU, PONTIAC Vehicles - See Fitment Details (SPE-HPR7421) by Tony Battaglia

Let me start by saying that before installing this I cleaned the throttle body and air intake system on a recently purchased car. It wasn't that dirty, at least I can only compare it to my old car, I know. K&N filters are almost double the price and I heard about this brand from my local parts store. From what I've been told, they use them in their personal vehicles. The quality and durability is the same as the K&N brand but much less. My idle speed dropped by 300! Very gentle and quiet! Brilliant! Invest in it, it's totally worth the money!
