The K&N cold air intake system for 1997–2004 Ford F-150 V8 4.6L/5.4L uses a mandrel-bent aluminum intake tube and a washable, reusable oiled cotton high-flow filter to deliver a guaranteed increase in horsepower and torque. The oversized filter design may allow up to 100,000 miles between normal highway servicing, and included heat shields help protect intake air from engine-bay heat while most kits install in under 90 minutes.
