Product Overview

Stock intake manifolds have sharp bends and corners. As air flows around these corners, dead air zones are created. These dead air zones choke down the air and restrict airflow to your engine.

aFe's MDV technology uses smooth bends and directional vanes to form multiple air paths through the manifold. These new paths are smoother and shorter, producing much smaller dead air zones for increased overall airflow to
the engine.
• Unique airflow path with MDV Technology
• Proprietary internal bolt design - guaranteed to not deform and leak
• Cast A356-T6 aluminum construction
• Up to five port pads
• Custom black-zinc finished steel bracket of OE wire harness
• Faster turbo spool-up
• More horsepower
• Increased low-end torque for more towing power
• Improved boost pressure
• Stainless steel hardware

BladeRunner exhaust manifolds from aFe are made from 304 stainless steel and feature a one-piece design with reinforced ribs between each exhaust port. This increases strength and eliminates the cracking found in most stock and aftermarket units. These manifolds feature two EGT probe ports, a thick wall design for increased strength, matched ports, and a merged runner design to maximize exhaust flow. Once you've installed a BladeRunner on your ride, you'll be able to feel improved turbo spool-up times, throttle response, and decreased EGTs. For top performance, choose an exhaust manifold from aFe.
