K&N 63-3109 Multicolor Cold Air Intake sku-801604015

The K&N Multicolor cold air intake kit, model 63-3109, is listed as SKU sku-801604015 and UPC 024844373038. It is for 2019 Chevy/GMC Silverado 1500 and Sierra 1500 vehicles with a 5.3/6.2L V8 engine. K&N says dyno testing showed increased horsepower and acceleration without an ECU tune, with up to 50% more airflow than the factory air box and intake tube.

The kit is also described as improving throttle response and uphill performance while towing, changing engine sound and filtering harmful contaminants. It has a 10-year/million-mile limited warranty. K&N says the filter needs no cleaning for up to 100,000 miles and that installation takes less than an hour with basic hand tools.
