Turbocharging and direct-injection are quickly becoming the go-to method for building powerful and efficient trucks. However, if not carefully maintained, they can also mean the end for your 2017-2021 Ford F-150 3.5L EcoBoost. Direct injection makes the 3.5L EcoBoost one of the most efficient engines ever fitted to the F-150. But, without the benefit of fuel washing over the back of the intake valves, blow-by is free to accumulate in the form of carbon deposits. Eventually, those carbon deposits can choke your engine and reduce its performance. Thankfully, Mishimoto has a solution. Mishimoto's 2017-2021 Ford F-150 3.5L EcoBoost Catch Can Kit protects your intake tract and valves from the harmful effects of blow-by and carbon accumulation. The dual-can setup ensures that blow-by is routed away from your intake and valves in all driving conditions. Our road-proven 12 fl. oz. baffled catch can holds more blow-by for extended service intervals. Whether you're hard on the throttle or cruising around town, these cans have your engine's back. The powder coated, 3mm-thick steel bracket is strong enough to handle any terrain a work truck or daily driver will see, and the pre-installed quick-disconnect fittings make installation a breeze. Of course, this catch can kit is backed by our Mishimoto Lifetime Warranty so you can rest easy knowing your 2017-2021 F-150 3.5L EcoBoost is protected from blow-by for as long as you own it.
