These SPD High Flow Turbo Adapters replace the factory adapters on 2011 – 2017 (including Gen 2) F150s, F150 Raptors, Expeditions and Navigators that have the 3.5L Ecoboost engine. These larger adapters will maximize flow, greatly reduce exhaust backpressure and help to lower Exhaust Gas Temperatures.

SPD dyno’d a completely stock 2016 F150 3.5 Ecoboost and got 338HP and 386LBS of torque at the wheels. After these SPD High Flow Adapters were bolted on, with no other modifications, the truck made 359HP and 403LBS of torque. That’s an increase of 21HP and 17LBS of torque at the wheels!


SPD  tested a 2017 Raptor and measured an increase of 24HP and 43ft-lbs.

These high flow adapters will directly bolt on to the factory turbo. And any other “drop in” style turbos that will accept the stock adapter. These will work with the factory downpipe or any aftermarket downpipe that bolts up to the factory adapters.

The SPD high flow turbo adapters will come as a pair (2 High Flow Adapters). With a stud socket included.

An install kit is required when installing the adapters, and is also available on our site here: SPD Adapter Install Kit
