Twin Air Filter's patented design, high quality materials and superior construction deliver unbeatable performance and protection - and make Twin Air Filters the hands-down choice of more World and National Champions than all other filters combined.

An air filter is your engine's only protection against the elements, and your stock filter isn't up to the task. Replace it with a Twin Air- the number 1 filter system proven on motocross tracks around the world.

Twin Air's fused layers of open-pore foam and fine inner foam trap even the smallest particles-without restricting airflow

Dual stage foam: 2 different pore sizes create more trapping area for even the smallest dust particles.

Flame laminated foam: Both "Stages" are not glued but heat sealed to provide maximum air flow.

Light color foam makes it easier to see where the filter oil has covered and where it has not.

This kit includes all necessary components to repair your carburetor.

O.E.M. jet sizes are included in the kit.

Perfect for Dirt Bikes with a stock engine using the stock airbox, air filter, and pipes.

Stage 1 Jet Kits are engineered to improve throttle response and deliver approximately 5% more horsepower than stock.

These kits are fully adjustable to allow the use of well-designed aftermarket pipes and stock replacement air filters, like K&N.
