The K&N 77-3058KP is a cold air intake kit for 2007-2008 Chevrolet, GMC, and Cadillac V8 trucks and SUVs with 4.8L, 5.3L, 6.0L, or 6.2L engines. The manufacturer built it around a mandrel-bent aluminum intake tube and an oversized, oiled cotton-gauze filter that takes the place of the factory air box and filter. Shoppers comparing it with a generic cold air kit should note that it is sized for these specific engines, so the tube and hardware are meant to fit without modification.
Stock intake housings restrict airflow, and the manufacturer says this system smooths and straightens the intake path so the engine can draw in more air. The manufacturer states the kit is guaranteed to increase horsepower and torque, and lists estimated gains of 12.49 HP at 4917 RPM and 13.3 lb-ft of torque. Because those figures are estimates, confirm them with the manufacturer before you budget around them. The filter is washable and reusable, and the manufacturer says it needs cleaning only about every 100,000 miles under normal highway driving, which cuts down on repeat filter purchases over the life of the truck. Search terms this kit tends to match include 2007 Silverado 5.3 cold air intake, 6.0 Escalade intake kit, reusable cotton gauze truck air filter, and K&N 77 series 4.8 intake.
Yes. The manufacturer states the kit replaces both the factory air filter and the stock intake tube.
The manufacturer says the filter only requires cleaning about every 100,000 miles under normal highway driving conditions. Owners on user forums note that heavier dust or off-road use may call for more frequent service.
The manufacturer lists RU-1042 as the replacement filter for this system.
The kit replaces the factory air filter and intake tube, so installation is mainly a matter of removing the stock air box and tube and mounting the aluminum tube and filter in their place. The package includes seven stainless steel clamps and three couplers, so check the hardware against your parts list before you start. Install difficulty, required tools, and torque specs were not confirmed in this research, so review the manufacturer's install sheet before starting, and keep the filter clean and oiled after installation.
