SuperMAXX Stainless Long Tube Headers are an excellent way to bolt on 20 hp and 14 Ft. Lbs. of Tq. to your 2004 – 2008 Ford F150 Truck with a 5.4L engine.

Fits with automatic or manual transmissions and takes about 4-6 hours to install. Comes complete with a detailed, full color instruction manual for easy installation. O2 Extension cables, triple layer stainless steel gaskets, header bolts and all installation hardware are included. Designed for use with Dynatech intermediate sections (part numbers 722-62220, 722-62230 or 722-62320) .
