aFe Bladerunner Ductile Iron Manifolds Exhaust Dodge Diesel Trucks 03-07 L6-5.9L (td)

This aFe Bladerunner exhaust manifold is built from ductile iron to replace cracked factory manifolds on 03-07 Dodge 5.9L Cummins diesels.

Key Features

• Ductile iron construction — stronger and more resistant to cracking than stock cast iron.
• Thick wall flange (0.25") — prevents warping and cracking common in factory manifolds.
• Matched ports and merged runner design — reduces backpressure and improves exhaust flow.
• Improved turbo spool — quicker response from your turbocharger.
• Better throttle response — makes the engine feel more lively.
• Two EGT probe ports — allows for monitoring of exhaust gas temperatures.
