+21HP and +17TQ increase! See dyno. The truck tested was 100% stock 2016 F150 3.5L Ecoboost with just SPD's adapters installed.
SPD's high flow turbo exhaust adapters replace the factory adapters on 2011-2018 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 2.3125" 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.
This adapter is made in USA from high quality forged steel. This adapter will directly bolt onto factory turbos or any other"drop in" style aftermarket turbos that will accept stock adapters. These will accept any factory or aftermarket down pipes.
There are 2 High Flow Turbo Exhaust Adapters per kit.
SPD Turbo adapters also fit the following vehicles.
2011-2018 Ford F-150 3.5L Ecoboost
2015-2018 Ford Expedition
2015-2018 Lincoln Navigator
