Description

Remove unnecessary restrictions but replacing your factory turbo adapters with our high-flow CAST stainless steel units.

This very small modification will dramatically improve the performance of your 3.5L EcoBoost motor. Our engineers redesigned the mouth to be 55.4% wider compared to OEM, thus reducing the backpressure and improving spool up from the turbos.

Our adapter kit is machined from cast 304 stainless steel on our in-house HAAS 750 mill. The flange matches the factory gasket at the turbo but has a larger opening for the downpipe compared to stock. This is a must when installing performance exhaust downpipes!

Power gains can be up to 20hp.
