The K&N 57-3017-2 is a cold air intake kit for 1996–2005 Chevrolet S10 and Blazer and GMC Jimmy models with the 4.3L V6. It pairs a rotationally molded high-density polyethylene intake tube with an oversized conical oiled-cotton filter and a custom heat shield that blocks hot engine-bay air. K&N claims a guaranteed gain in horsepower and torque, and the washable filter can go up to 100,000 miles between cleanings in normal highway driving. It suits owners of these aging trucks who want a reusable filter and a modest power and sound bump; it is not a tune, and CARB status varies by part, so California buyers should verify legality first.

This cold air intake system is made for 1996-2005 Chevrolet S10 and Blazer and GMC Jimmy models with the 4.3L V6 engine. It is a K&N product and is not created or sold by Chevrolet.
The intake tube is rotationally molded from high-density polyethylene (HDPE) to increase the volume of airflow to the engine. It is paired with a washable, reusable High-Flow Air Filter with oiled cotton filter media. A custom heat shield helps protect intake air from the high temperature of the engine bay.
The oversized, conical filter design allows up to 100,000 miles between filter services under normal highway driving conditions. The system can typically be installed in less than 90 minutes. Some intakes are not legal for sale or use on any pollution controlled motor vehicle in California, so check the product specifications for the CARB status of each part.
