K&N Cold Air Intake Install How toA fuel injection performance kit helps your vehicle catch its breath
Performance is a lustful thing for car enthusiasts. For true "car guys," there's no such thing as "enough." Take the '99 Tahoe Limited, for example. It's a nicely appointed sport-utility vehicle with plenty of power for the highway-for some people. Anyone who's interested in performance will soon notice that the off-the-line jump could be better, and the engine seems a bit flat when you stomp on the gas.
However, this lack of throttle response isn't anything that a good 10 to 15 more horsepower won't cure. In order to legally drive the vehicle on the street, the challenge then becomes finding a product that gives such a boost while remaining legal in all 50 states in this day of tightly regulated engine systems. K&N Engineering's Fuel Injection Performance Kit (FIPK) is just such a product.
K&N's FIPK assures that cool air is directed into your engine for better combustion, and the patented, low-restriction Filtercharger allows the engine to inhale a larger volume of air compared to the OEM filter assembly. The system works with the OE computer and emissions system and is backed by K&N's 10-year/Million-Mile Limited Warranty.
The kit isn't complicated to install, and the work can be done in your driveway with simple hand tools in about two hours. We chose to have the kit installed at Performance Products. The company has installed many K&N systems, so they completed the job in about an hour and a half. If you do it yourself, you will need 7/16" and 5/16" wrenches, a 13mm socket, a 7/32", 7/16", and a 3/8" socket, a 1/8" Allen wrench, a 5mm Allen wrench, a ratchet, and a flat-blade screwdriver.
After installing the K&N FIPK, start the engine with the transmission in Neutral or Park and the parking brake engaged. Listen for air leaks or odd noises. For air leaks, secure the hoses and connections. For odd noises, find the cause and repair it before proceeding. This kit will function identically to the factory system except for being slightly louder and much more responsive.
Test-drive the vehicle. Listen for odd noises or rattles and fix as necessary. K&N suggests checking the Filtercharger element periodically for excessive dirt buildup. When the element becomes covered in dirt (or once a year), service it according to the instructions on the Recharger service kit that is included in the kit.
