Since its introduction in 2010, the EcoBoost line of V6 engines has proven to be a fantastic alternative to large-displacement V8 options. Ample tuning potential and gobs of torque, all while returning great fuel mileage, make the EcoBoost platform a winner in our book. But, allowing your engine to breathe easier through intake and exhaust modifications can take the already impressive EcoBoost to another level of performance. That's why Mishimoto has developed this turbo inlet tube kit for your 2017-2020 Ford F-150 3.5L EcoBoost.This turbo inlet tube kit boasts an internal volume increase of up to 61% over the stock inlet pipes to allow your turbos to pull in as much air as they could ever need. Our engineers have also removed bottlenecks and other obstructions to reduce restriction by up to 23% over stock. All of this is achieved while protecting the intake charge from engine bay heat with a cross-linked polyethylene (XLPE) construction. This material is ideal for withstanding high engine bay temperatures and resists degradation from fuel and oil.To make this kit's reliability match its performance, we've CNC-machined every vacuum fitting from aluminum for a leak-free fit. The included EVAP fitting has also been CNC-machined and flow bench tested to 100% match the OEM part and ensure CEL-free performance. The Mishimoto turbo inlet tubes perform perfectly on the stock tune and fit with both the stock air intake box and the Mishimoto F-150 EcoBoost Performance Air Intake.The Mishimoto 2017-2020 Ford F-150 3.5L EcoBoost turbo inlet tube kit includes both turbo inlet tubes, DuraCore™ silicone couplers, and stainless-steel clamps for a hassle-free installation. So, toss your restrictive stock turbo inlet tubing in the trash and upgrade your intake airflow with the Mishimoto turbo inlet tube kit. As with all our F-150 EcoBoost products, this kit includes our signature Mishimoto Lifetime Warranty for a lifetime of performance.
