2008-2009 Kawasaki KFX450R K&N Air Intake Adds Horsepower & Torque
- Feb 19, 2016
In each segment of the motorcycle and ATV market there always seems to be one manufacturer that makes a do-it-all product, and it’s not always the same manufacturer. It may be Honda in one segment, Yamaha in another, and Kawasaki in yet another. This jack-of-all-trades probably isn’t the absolute fastest around the track, maybe doesn’t make the most peak horsepower, and isn’t necessarily the most ergonomic for long trail rides, but it does check every checkbox and checks them quite well. The 2008 to 2009 Kawasaki KFX450R is exactly this quintessential jack-of-all-trades. It can keep pace on the track with an advanced, digitally-controlled fuel-injected engine while still having the convenience of a reverse gear to help keep trail riding enjoyable. Its suspension and brakes setup can whip the rear end around corners while still being comfortable enough for longer adventures. Whether your KFX450R is a track-day titan or weekend trailblazer, unlock some additional performance from that advanced engine with the K&N 57-1124 performance air intake system.
The 57-1124 is guaranteed to increase horsepower on the 2008 and 2009 Kawasaki KFX450R ATV. Off-road racing and riding are extremely dirty, physically demanding environments, and the 57-1124 is built to withstand the abuse. A strong, high-density polyethylene intake tube replaces the factory one which helps to streamline airflow into the engine. Streamlined airflow means your engine can fill the cylinder more efficiently and make more power. The system also makes accommodations for the factory crankcase vent line and inlet air temperature sensor; while a heat shield shrouds the filter from heat coming off the engine. A K&N RC-4630XD extreme duty air filter is fitted to the end of the intake tube and covered with a RC-4630DK Drycharger pre filter wrap to provide excellent air filtration and engine protection. This air filter is constructed with K&N’s XD filter media which is tighter-weave cotton gauze in 4 pleated layers to ensure the incoming air stays clean even in the dustiest of environments. Another benefit of the RC-4630XD filter’s design is it’s washable and reusable. When the dirt exceeds the wire mesh, simply service the filter with a K&N Recharger kit and you’ll be back on the trail in no time.
All of these superior components come together to deliver superior airflow and superior performance. On the dyno, a 2009 Kawasaki KFX450R equipped with the K&N 57-1124 produced an additional 4.5 horsepower and 3.3 pound-feet of torque at 7100 rpm over the factory air intake. For a small 449cc engine, that’s a noticeable increase in power. The 57-1124 KX450R air intake system from K&N is an easy-to-install upgrade and comes with step-by-step instructions, including a list of the tools required to install it. Installation can usually be completed in 90 minutes or less. Also, K&N backs the 57-1124 with a One-year/Unlimited Mileage Warranty so owners can have the peace of mind that their new intake system will withstand the wear and tear of off-road romping.
Sometimes, unfortunately, a jack-of-all-trades can be a master of none. Thankfully, the Kawasaki KFX450R isn’t a master of none. It performs admirably on the track as well as the trail and with a 57-1124 performance air intake system installed; you’ll have a leg up on the competition.
