Pair of Large-Diameter, Drop-In Turbo Flange Adapters
The mighty 2017-2020 Raptor’s 3.5L HO EcoBoost makes awesome levels of horsepower and torque.
SPD’s high flow turbo exhaust adapters replace the factory adapters on 2011-2020 F-150 3.5L Ecoboost motor. These larger advanced adapters will maximize flow, greatly reduce exhaust back pressure and help to lower Exhaust Gas Temperatures. We have seen reductions of 100-200 degrees at 65mph at the cats. The SPD adapters has an outlet of 2.38″ ID compared to the stock outlet which is 2.0625″ ID. Another benefit of the SPD Adapters is reduction in turbo lag. Customers have noticed that the turbo spool much quicker.
100% stock 2016 F150 3.5L Ecoboost with just SPD’s adapters installed had an +21HP and +17TQ increase at the rear wheels! See dyno.
A 100% stock 2017 F150 Raptor made +24HP and +43lbs of TQ at the rear wheels.
