Add more power to you 2011-2014 F150 ?Coyote? with V8-5.0L engine by installing our new ?Race Only? Twisted Steel? headers. These headers feature a 1-5/8? mandrel-bent tuned length primary tubes that will out-flow the stock cast manifolds by 46%. These headers are built using 409 stainless and thick 3/8 flanges for a leak-free seal. We designed the headers to incorporate a merge collector (header collector). A merge collector combines high flow and velocity to increase and broaden the engines torque curve, while reducing turbulences that are found in traditional form collectors. When combined with our off-road or catted y-pipes performance gains are increased as much as 10HP and 20 lbs. x ft of torque over the stock manifolds and factory y-pipe.

The new Twisted Steel performance header from aFe Power is redefining the header industry with new pulse control technology. aFe engineers have designed this header using optimum tube lengths and mitered collectors for maximum flow and velocity for power delivery across the entire power band. Combine with a large 1/2" thick head flange and 14-gauge 409 stainless steel tubing, you have a header that is strong and powerful. Twisted Steel headers are 100-percent bolt-on with no modifications necessary and are proudly engineered and built in Corona, CA.
