By virtually eliminating airflow restrictions, the K&N 57-1128 FIPK Performance Intake System can make your 2006, 2007, or 2008 Suzuki LTR 450 QuadRacer into a QuadWinner

From the very beginning, the 2006-2008 Suzuki LTR 450 QuadRacer was intended to be a race-ready factory hotrod. During its development, Motocross Champion Doug Gust worked with Suzuki engineers to create a powerful, track-ready quad that was predictable, and easy to control. They gave it a wide track front and rear, with a fully adjustable suspension that could be quickly modified to suit the rider's weight and track conditions.

A special lightweight frame kept the engine and the center-of-gravity down low. And the race-derived 450cc motor featured dual overhead cams, fuel injection, and (approx.) 41 screaming horsepower. With just 368 lbs (dry weight) to lug around, the Suzuki QuadRacer LTR450 is fast enough for the average rider. But if you're looking for a competitive edge at the track (or around your buddies), the K&N 57-1128 FIPK Performance Air Intake System can add an estimated 2.7 horsepower, and transform the way your quad rides.

In order for an engine to burn fuel and make power, air has to be drawn into the cylinder to act as a catalyst during combustion. Normally that air is brought in through the factory intake system, which uses a series of narrow tubes to funnel air through the restrictive paper air filter, to the throttle body. But as that air is forced around sharp curves, over uneven surfaces, and into different sized tubes, it starts to heat up and gains turbulence, which causes it to lose some of its combustion potential.

To recapture some of that lost horsepower, the K&N 57-1128 FIPK Performance Intake System creates a more direct airflow path to the engine. A larger, aerodynamically designed HDPE intake tube replaces the smaller factory unit, and links the throttle body directly to the oversized K&N high-flow air filter. This allows lots of clean air to go right into that big 450cc cylinder, without having to travel around a bunch of twists and turns. A sturdy powder coated heat shield mounts in place of the stock air box, and helps to keep the intake system free of warm engine air. Plus, the reusable cotton gauze air filter can be quickly cleaned after a dust-filled race to maintain optimum airflow.

To aide installation, and make this K&N 57-Series FIPK Performance Intake System completely legal in all 50-states, the Suzuki 450's inlet air temperature sensor plugs into a fitting on the back of the heat shield. And there's also a fitting on the intake tube for the crank case vent hose. Since you won't have to make any modifications to appease the sensors, you'll be able to install the FIPK intake system in around 90 minutes.

K&N installed 57-1128 on a stock 2008 Suzuki LTR450 (you can see pictures of it in the installation guide), and the dyno tests revealed an estimated increase of 2.74 horsepower and 2.17 ft-lb of torque. The additional air also improved the throttle response and engine sound. But your individual results may vary, due to the mileage, modifications, and condition of your specific Suzuki LT-R450 QuadRacer.

By virtually eliminating airflow restrictions, the K&N 57-1128 FIPK Performance Intake System can give your 2006-2008 Suzuki LTR 450 QuadRacer enough extra horsepower to go from a QuadRacer to a QuadWinner.
