Give your self a break and your dirt bike a boost of performance with the Loud Mouth High Performance Air Intake Kit. The Billet Series Loud Mouth Intake Systems are engineered and CNC machined in-house from a solid block of 6061 billet aluminum to maximum tolerances, making this one of the lightest bolt-on performance products in the industry. This new design eliminates the weld of the flange to the intake housing and significantly increases the integrity of the product. The perfected universal air filter setup eliminates the need for the O.E.M. filter cage and/or backfire screen and creates a higher velocity, obstruction free airflow entering the intake tract. Most motocross riders will find a power boost in the bottom end with extended top end rev performance. The Loud Mouth intake kit is also known to reduce low-end bog. Maintenance time will be dramatically reduced with the simple installation of the air filter to Loud Mouth mounting bracket that provides a perfect seal to lock out dirt. 4.75" diameter inlet significantly increases velocity of airflow entering engine. Cooler intake charge. Boosted horsepower, torque and instant throttle response. Improved airflow allows bike to start easier in fewer kicks. Amazing high performance intake sound (within legal dB limits). Revolutionary cageless filter design is 100% obstruction free. Provides the best seal ever available for the modern motocross bike. Clean air box even in the most extreme conditions. Quick 30-second filter changes. Easy installation, no jetting / mapping required.
