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.
