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. ***FOR OFF-ROAD USE ONLY*** Features:

• One of the largest turbine adapters on the market
• Less backpressure
• Faster spool from the turbos
• CNC machined from cast 304 stainless steel
• 55.4% larger area for maximum exhaust flow
