Unrestricted Intake for Better Power.
The K&N Series 77 High Flow Performance Cold Air Intake uses a massive conical air filter and an aerodynamically streamlined tube to draw many additional cubic feet of air into your 1997-2003 F-150’s 4.6L engine. Built to keep engine heat at arm’s length with a thoroughly sealed heat shield, this component cranks up the throttle response, fuel efficiency, and overall performance of your truck’s engine with a minimum of changes. Getting your pickup engine breathing more freely results in measurable power gains, too – up to +9.7 horsepower and +11.44 ft-lbs of torque.
The stock tune on your F-150’s engine computer or ECU (electronic control unit) is fully adequate to running the K&N Series 77 High Flow Performance Cold Air Intake. There is no need to flash the engine with an aftermarket tune after installing this component.
Tough Filter that Can Be Reused.
Measuring a colossal 9” high, the filter element in the K&N Series 77 High Flow Performance Cold Air Intake is chrome topped and made from oiled cotton gauze. Twin aluminum, epoxy-coated screens are sandwiched into the layers for improved toughness. The filter is completely washable and reusable – the first cleaning is usually needed at 100,000 miles, and the element can be cleaned, re-oiled, and reused many times thereafter.
High Quality Construction in the USA.
Made in America, the K&N Series 77 High Flow Performance Cold Air Intake features a powder-coated steel air box finished in textured black. The edges of this box are fully surrounded by EPDM foam sealing strips to ensure that the fit is snug and engine heat is excluded from the filter. The intake tube is made for maximum flow, with unrestricted mandrel bends. Making it immune to rust and most corrosion, the tube is fabricated from aluminum and given a high, attractive polish.
Accepts the Factory MAF.
The K&N Series 77 High Flow Performance Cold Air Intake is made to have the stock MAF swapped over directly from the OE intake, and therefore has a MAF housing designed to fit that component. It also features attachments for the EVAP vent hose and crankcase vent hose.
Attaches with Simple Tools.
Using regular hand tools, the K&N Series 77 High Flow Performance Cold Air Intake attaches to your F-150’s engine in under 90 minutes. This is a no-drill installation that needs no cutting or modifications, and uses the hardware included with the kit.
Million Mile Warranty.
A standard 1 million mile warranty from the manufacturer covers the K&N Series 77 High Flow Performance Cold Air Intake.
