Review on 🚀 K&N Cold Air Intake Kit: High Performance Horsepower Increase, 50-State Legal: Compatible with 1997-2004 Ford F150, F150 Heritage, F150 Harley Davidson, Expedition (Part Number: 57-2541) by Jonathan Clark

Fits 1998 Ford F150 with 5.4 engine. Good instructions with quality parts and accessories. The initial ride seemed to add some throttle response and the difference in acceleration is noticeable. Intake only, but there seems to be more torque at part throttle. I understand that there isn't supposed to be an increase at part throttle, but something works differently. Full throttle acceleration sounds like my old 4 cylinder razor. A pleasant surprise. The installation time was 1.5 hours. The MAF sensor has been removed quite a distance from the throttle body, but the new assembly seems to work fine. A good product.
