The K&N 57-1536 is part of K&N's 57 Series FIPK line, built for the 8.3L V10 in 2003–2006 Dodge Vipers. It is a cold air intake with a high-flow, roto-mold tube that uses a high-density polyethylene (HDPE) tube to increase airflow volume. Its oiled cotton filter is washable and reusable, which is the main reason to pay more than for a basic drop-in filter. Per the manufacturer, the filter can run up to 100,000 miles between filter services under normal highway driving conditions, so you avoid repeat filter purchases. The manufacturer also states the system is guaranteed to increase horsepower and torque. Owners on user forums have questioned how much cold-air intakes add on this V10, though those discussions centered on the SRT-10 truck.
Fitment is listed for the Viper, so confirm the application before ordering for a Ram SRT-10, which shares the 8.3 L V10 in a different chassis. Plan a careful DIY session. Expect to disconnect the battery and air sensor, remove the factory airbox, seat the heat shield and filter adapter, and reconnect the sensor and crankcase vent hoses. Check each clamp and joint, then start the engine and listen for air leaks before driving. Searches for 2003-2006 Viper SRT-10 cold air intake, K&N 57 Series FIPK install, and Viper V10 washable oiled cotton filter will find this kit.
The manufacturer states the filter can go up to 100,000 miles between services under normal highway driving conditions. Cleaning frequency will be shorter in dusty or harsh conditions.
The manufacturer says the system is guaranteed to increase horsepower and torque, but I could not confirm a specific figure on its own pages. Numbers circulating elsewhere vary, so confirm with the manufacturer before relying on one.
Installation is a moderate DIY job that needs hand tools, a ratchet set, and a screwdriver. A Viper-specific install sheet from the manufacturer was not confirmed in my research, so check the included instructions for torque and routing details before starting. Common gotchas include brittle factory clamps and hoses, sensor connectors that are hard to reach, and hood-area clearance once the tube is routed. Work with the engine cold, and recheck every clamp after a short test drive.
