Review on K&N Cold Air Intake Kit: Maximizing Performance, Boost Horsepower: Fits 2002-2005 Chevy/GMC/Oldsmobile (Trailblazer, Envoy, Bravada) 4.2L L6, Model 77-3036KP by Jim Moody

My kit was missing the main hose (coupling connecting the intake housing to the throttle body). nowhere to be found The intake manifold was also badly dented in several places. Both holes connecting to the throttle body and filter were visibly deformed like they were pinched or something. It seems clear that I received a used kit that was returned by another buyer. The K&N part itself is well made and I'm happy with it, but it's definitely 1 star for me. Buy this part, but definitely do not buy it from this list unless you are willing to pay a large amount and risk receiving a used kit with missing and damaged parts.
