K&N 57-1121 FIPK Performance Air Intake was designed for the 2008, 2009, 2010, or 2011 Yamaha YXR700 Rhino

Designed to make work fun, the Yamaha Rhino is a capable sport UTV that has plenty of room for 2 people and 400 lbs of cargo. Or, you could pile 1,200 lbs of your stuff into a trailer and pull it behind you. The Rhino practically invented the sport Side by Side segment when it was introduced over a decade ago. And the 2008-2011 Yamaha YXR700 Rhino continued to set new UTV benchmarks, with innovative features like fully locking shift-on-the-fly 4WD, a fully independent suspension with 7.3 inches of travel and optional adjustable shocks, and front/rear disc brakes with automatic engine braking. Whether you want to spend the day riding trails, or getting stuff done on the 'back-40', the 40-hp motor in the Yamaha YXR700 Rhino will get you where you need to go. But if you want to give your Rhino a bit more 'charging' power (pardon the pun), the K&N 57-1121 FIPK Performance Intake System can add an estimated 3-hp, by simply allowing the engine to breathe.

2008-2011 Yamaha YXR700 Rhino

Whether you want to spend the day riding trails, or getting stuff done on the 'back-40', a K&N air intake for 2008-2011 Yamaha YXR700 Rhino models will help get you where you need to go

The 2008-2011 Yamaha Rhino's fuel injected 686cc engine makes power by igniting a combination of gasoline and air inside its single cylinder. The gas is pulled from the tank, and then sprayed under pressure, directly into the cylinder. No big deal. The air on the other hand, has to first travel through the dirt-caked paper air filter inside the stock air box, and then it has to traverse the obstructions and tight bends inside the narrow intake tube. The air then arrives at the throttle body swirling and hot. Since warm air doesn't contain as much oxygen as cold air, these uneven spurts of warm air won't burn the fuel inside the cylinder as efficiently as it could. The K&N 57-1121 FIPK Performance Air Intake System is designed to provide a more direct airflow path, virtually eliminate air turbulence, and remove air intake tract restrictions. This allows a high volume of cool air to be delivered right to the throttle body, where it can be used to more effectively burn the fuel and create additional horsepower.

To improve the performance of your 2008-2011 Yamaha YXR700 Rhino FI, the K&N 57-1121 FIPK Performance Intake System replaces restrictive factory components

To improve the performance of your 2008-2011 Yamaha YXR700 Rhino FI, the K&N 57-1121 FIPK Performance Intake System replaces that accordion-like factory intake tube, with a much larger roto-molded HDPE (high density polyethylene) intake tube. This smooth-bore tube is shorter and wider than the stock tube, so the air can flow directly through the K&N air filter, and right into the engine. A rugged heat shield helps keep the filter from collecting warm engine air, and it fits in place of the stock air box.

Thanks to its aerodynamically optimized straight-flow design, installing the entire system should take about 90 minutes. The cotton gauze air filter is positioned within easy reach. So every time your Rhino gets covered in mud/dirt/whatever, you can just pop it off, clean it using a K&N Recharger kit, and stick it back on. K&N air filters are extremely durable and will provide years of performance and engine protection.

Back in 2008, K&N installed a K&N 57-1121 FIPK Performance Intake System on a stock 2008 Yamaha Rhino 700, and the dyno chart showed an estimated horsepower increase of 3.18-hp. The improved airflow also caused the engine to sound better, and respond more quickly to throttle inputs. But your individual results may vary, due to the mileage, modifications, and condition of your specific 2008-2011 YXR700 Rhino.
