K&N Air Intake Kit Provides a Power Boost for the 2003-2004 Toyota 4 Runner

       Printer Image
If you own a 2003 or 2004 Toyota 4 Runner with a 4.7L engine you are in luck! K&N recently released a new 77-Series intake system, part number 77-9022KP, for the 2003-2004 Toyota 4 Runner which is guaranteed to provide more horsepower. In fact K&N tests have shown a horsepower gain of 12.77 HP @ 5007 RPM for this intake. You can especially feel this added power and torque when accelerating and when towing a load. This intake, like all other K&N intakes, was engineered specifically to work within the vehicle's computer specifications while maximizing power and allowing air to flow with little restriction. One noticeable design characteristic of this air intake is the reduction in diameter just before the mass air sensor. It would be far easier to use the same diameter throughout but that won't provide the best engineered solution!

It takes about 90 minutes or less to install this kit and the lifetime K&N air filter performs for up to 100,000 miles before service is required. You would go through a lot of clogged paper filters before this K&N filter will need servicing. There is also a million mile limited warranty on all K&N 77-series high performance air intake systems. K&N manufactures hundreds of air intake kits.
