Review on 🚀 Boost Performance with K&N Cold Air Intake Kit for 2004-2005 CADILLAC CTS-V: Increase Horsepower, 50-State Legal, Model 57-3054 by Jay Blo

I bought this for my 2004 CTS-V and installed it myself in about 15 minutes. Easy installation and perfect fit. The only issue is the whistling at certain RPMs, but I'm sure if I do more research I can fix it. The sounds blend better, but not too loudly while driving, only under heavy loads on the engine when you want it to unleash power. Is worth the money and comes perfect with great instructions.
