Inexpensive & Quick Way To Boost Horsepower

You can always trust the brilliant intake engineers over at K&N Filters to design something special for your Ford F150, and the 77-Series High-Flow Performance Air Intake Kit does not disappoint. Adding a cold-air intake is a perfect way to get some easy power and performance gains for your truck. The 77-Series Cold Air Intakes are up-gunned versions of K&N's more standard cold air intake kits. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow, allowing your truck's engine to inhale a larger amount of air than the restrictive OEM air filter assembly.

Performance Air Filter with Heat Shield and Inlet Tube

When they designed their 77-Series kits, K&N dug up the largest air filter that they could possibly fit in place of your truck's factory air box and built the rest of the system around it. The filter is one of K&N's classic high-flow cotton filtration systems that brings in a much larger volume of air than stock along with improved filtration. Along with the filter, each K&N 77-Series kit comes with a full heat shield assembly and a highly efficient inlet tube that works together to promote improved airflow into your truck's engine over the stock air box. A bonus about this kit is that the filters are washable and reusable, or you can purchase replacements.

Installation Note: Included in this kit are detailed instructions and all the hardware you'll need for a relatively quick and easy installation (est: 90 minutes).

CARB-Approved for 2015 F150s: this intake kit is 50-State Street Legal for 2015-2017 F150s only under CARB EO# D-269-46. CARB approval for 2018 and 2020 F150s is still pending.
