aFe POWER Twisted Steel Headers (2007-2011 Wrangler JK)

aFe Power's new "Race Only" Twisted Steel Headers deliver 6 hp and 6 lbs. x ft. torque while outflowing the factory exhaust manifolds. The headers are constructed of 1-1/2" 14-gauge 409 stainless steel tubing with 3/8" thick flanges to ensure a leak free seal. To eliminate dead space that can cause turbulence and hinder flow that formed collectors are prone to produce, true mitered merge collectors and optimized tube lengths are used for true pulse control technology improving flow and performance. The smooth curves and increased diameter of this header helps remove restriction and keeps exhaust gas flowing smoothly for improved performance and durability. All components are supplied for a hassle-free installation with no modifications necessary.

Factory Mounting Locations:
These headers retain your catalytic converters and are a direct bolt-on installation which requires no cutting or drilling to provide a hassle-free installation.

Mitered Collectors:
Mitered collectors decrease turbulence and increases exhaust velocity. The result is increased horsepower, torque and improved throttle response.

No Burnt Wires:
This kit includes 6 space age heat treated fiberglass boots that protects your spark plug wires up to 1200° F. These are included because they are necessary when installing aftermarket headers on your Jeep to prevent your wires from melting.

Heavy Duty 3/8" Flanges:
3/8" thick flanges prevent warpage to ensure a leak-free seal over the life of the vehicle.

aFe headers are engineered and manufactured in our Corona, California manufacturing facility.
