The K&N 57-2593 is a cold air intake built around a roto-molded HDPE intake tube and an oversized oiled cotton gauze filter. It replaces the factory air filter and intake tube on the 2.7L EcoBoost V6 in the Ford F-150. The manufacturer describes it as guaranteed to increase horsepower and torque and backs it with a lifetime limited warranty. A full tube swap addresses the restrictive stock airbox path, which a drop-in filter alone does not, so this kit is the better choice for buyers who want more than a filter change.
Set realistic expectations before buying. The manufacturer lists an estimated gain of 19.37 HP at 4500 RPM, but owners on user forums often report much smaller real-world gains on a stock calibration. Their most consistent positives are a cleaner induction sound and slightly sharper throttle response. Forum regulars generally pair an intake with a custom tune when chasing meaningful output. The cleanable filter, which the manufacturer rates for roughly 100,000 miles of normal highway driving between cleanings, removes recurring filter purchases from the ownership cost.
The manufacturer lists this kit for the 2015-2017 Ford F-150 with the 2.7L V6. Sources vary on the year range, so confirm your truck's model year and engine with the manufacturer before ordering.
The manufacturer lists an estimated gain of 19.37 HP at 4500 RPM. Owners on user forums frequently report smaller gains on a stock calibration, and many say a custom tune is needed to make the intake's benefits more significant.
The manufacturer states the oiled cotton filter needs cleaning about every 100,000 miles under normal highway driving conditions. Owners on user forums note that applying the right amount of oil evenly is the fussiest part of cleaning.
The manufacturer lists a typical installation time of 60 minutes or less using simple hand tools, and the kit includes seven clamps. Plan for the factory air filter and intake tube to be removed in full, since the new tube and filter replace both. Owners on user forums advise cleaning the air box area and checking every clamp and joint for a tight, leak-free seal before driving. Reinstall the filter only after it has been oiled according to the manufacturer's instructions.
