Balance of Form and Function.
The K&N Series 57 FIPK Cold Air Intake w/ Heat Shield pumps an ample supply of cold, dense air into the combustion system to make sure your 1997-2003 F-150’s 5.4L engine – providing a guaranteed horsepower boost possibly as high as +13 hp. You can also expect maximum gains of +15 ft-lbs of torque – along with a thrilling performance sound that lets everyone know your truck is a hard-charging, well-tuned powerhouse. The aerodynamically engineered intake tube ensures maximum flow and the tough filter won’t need to be washed for 100,000 miles in most cases.
Functions with Stock Tune.
You don’t need to change your F-150’s stock tune in order to run the K&N Series 57 FIPK Cold Air Intake w/ Heat Shield. The CAI is built to function at full capacity with the OE tune left unaltered in the engine’s ECU (electronic control unit).
Massive, High Flow Filter.
The conical red filter in the K&N Series 57 FIPK Cold Air Intake is built to gargantuan proportions to properly pass and clean all the air which this high-flow system gulps in. Though use in very dusty or dirty environments may shorten this timeframe, the filter usually doesn’t need to be cleaned for the first 100,000 miles. After this, the red cotton gauze filter can be washed and reused again and again. The filter needs to be re-oiled after washing.
Stylish Looks, Reliable Sturdiness.
Designed to be good-looking in your F-150’s engine compartment as well as effective, the K&N Series 57 FIPK Cold Air Intake w/ Heat Shield features a black high-density polyethylene intake tube with a textured surface that mimics the interesting look of a textured powder-coat. The black design is set off by the 9-inch red filter and the shimmering polish of the stainless steel clamps that serve as fasteners for the component. This is a solidly-built, reliable piece.
Accommodates the Factory MAF Sensor.
The K&N Series 57 FIPK Cold Air Intake w/ Heat Shield is made to fit the factory MAF sensor, unmodified, into its structure. There are also precisely sized places for the crankcase vent hose, air bypass valve, and air temperature sensor.
