4.0TFSI Upgraded Exhaust Manifold ONLY

4.0TFSI EXHAUST MANIFOLDS ONLY!

These alleviate the cylinder 5 misfire issue by reducing EMAP caused by the extremely restrictive factory manifolds.

These drastically improve the volumetric efficiency of the 4.0TFSI engine. Not only will you have the exhaust flow to make more power, you will make that power more efficiently reducing strain on the engine by reducing backpressure.

These are an essential upgrade for anyone looking to make real power on the 4.0TFSI engine.

These manifolds are perfect for single turbo fabrication!

Now available with Inconel heat shields
