"The installation took a little bit of time, but K&N did tailor make the kit for this vehicle. It is a perfect fit and the quality of the parts are very good. The plastic threads for the one vaccuum nipple were a little difficult and getting the mass air sensor in was tight, but it was a success nonetheless. Their is not much increase in noise at low RPM's but at WOT when I romp on it - now my truck ROARS to life and the power increase at high RPM's is VERY noticeable. I did also notice a slight increase in my gas mileage too." —Isaac B from Dunmore, PA bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 1998 Toyota 4Runner.
"Considerable improvement in horsepower. Able to tow trailers with ease. Some improvement on gas mileage. Much easier to pass others, maintain higher speed with little effort." —Daniel D from Perris, CA bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 1998 Toyota 4Runner.
"Bought this kit for my 98 4Runner V6. Installation took about 2 hours since it was my first attempt. This kit was designed for the Tacoma, so there was a minor problem with a too-short vacuum hose in the kit that I corrected with a longer hose (8" or so). Other than that, installation was easy. It looks nice under the hood. I enjoy the extra boost in torque, as well as mileage. Over an 1800-mile trip, my 4Runner improved +1.5-2.0 MPG. There are some times when I see no improvement (around town) in which case the extra torque is the real benefit. On the highway, in addition to mileage, I found it much easier to pass a semi truck going uphill, where before with the stock induction my 4Runner was pathetic. Now it surges with newfound power! I definitely recommend this kit, you can't go wrong for such a low price." —Jonathan H from Avondale, AZ bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 1998 Toyota 4Runner.
