Review on 🚗 K&N Cold Air Intake Kit: Boost Horsepower, 50-State Legal: Compatible with 2002-2005 CHEVROLET/OLDSMOBILE/GMC (TrailBlazer, Bravada, Envoy), Part 57-3036 by Bomba Ton

Firstly, it will fit Chevrolet Trailblazer 02-05 vehicles, although the "Make Sure It Fits" label indicates it does not. Installation was pretty easy, the only thing I would recommend is buying a small hose clamp to attach to the crankcase ventilation pipe (not included). The audio is pretty low unless you really step on it, then it becomes very noticeable and will definitely drown out your radio. However, the heat shield is really bare and that air intake is still getting warm with the heat shield. Place. I'll probably hollow out the stock airbox to better insulate the filter since the cold air intake point is supposed to draw in COLD air. Two stars are deducted from the product for this.
