Product Description

The K&N RC-5052AB is a universal cold air intake system designed for custom or performance applications where a vehicle-specific kit is not available or desired. Its injection-molded housing and cold-air inlet work together with a washable and reusable cotton-gauze filter to deliver increased airflow and reduce intake air temperatures - which can translate into better engine breathing and improved throttle response.

Installation is flexible: the standard 70 mm base flange supports many intake setups, and optional stepped adapters allow fitting to alternative intake diameters. Because this is a universal kit, you'll want to verify your available intake tubing and flange size, as well as any clearance in the engine bay, before installation.

This intake system is ideal for performance enthusiasts building custom vehicles, turbocharged setups, high-RPM engines, or any application where the stock air intake limits airflow. While it provides high flow and excellent filtration, note that it may **not** be legal for highway use in certain jurisdictions with strict emissions regulations. When installed and maintained properly (cleaning the filter at the recommended intervals), the RC-5052AB delivers enduring value and performance upgrade potential.
