Product Description

The aFe Power BladeRunner Ported Ductile Iron Exhaust Manifolds (Part Number: 46-40114) are engineered to enhance the performance and durability of your 2007-2011 Jeep Wrangler JK equipped with the 3.8L V6 engine. By replacing the restrictive factory manifolds, these BladeRunner manifolds offer up to a 12% increase in exhaust flow, resulting in improved throttle response and overall engine efficiency.

Constructed from heavy-walled, industrial-grade ductile iron, these manifolds are designed to withstand high temperatures and resist warping and cracking. The machined inlet and outlet ports ensure a smooth transition for exhaust gases, optimizing flow and sealing. With two integrated EGT probe ports, you can monitor exhaust temperatures accurately. Installation is straightforward, as these manifolds bolt directly to the factory y-pipe without the need for modifications. Whether you're seeking enhanced performance or replacing cracked OEM manifolds, the aFe BladeRunner manifolds provide a reliable and efficient solution.
