Review on K&N Cold Air Intake Kit 57-3021-1: Boost Horsepower for 1999-2004 Chevy/GMC (Silverado 1500, Sierra 1500) 4.8L & 5.3L V8 Engines by Steven Lane

Apparent Power Boost

Installation is not difficult for a person with mechanical inclinations. My pickup required a small fan shroud trim. Be sure to check the packaging for all parts. The package I received was missing a filter adapter so I had to improvise with a Covid19 mask and gorilla tape. After contacting K&N, the item arrived a few days later.
