"I have installed after-market air filters on my vehicles for a number of years. This application on a 2007 5.3L V8 Trailblazer redefined tight fit. The clearance between the bottom of the actual filter and the area where the stock box had been installed was minimal. A part description was supplied, nodirections. The finished product seems to function well.K&N is much more user friendly. Installation time 40 minutes most due to the bottom clearance issue." —Lewis W from Northford, CT bought a Volant Cold Air Intakes for a 2007 Chevy Trailblazer.
