Twin Air Air Filter Dust Cover for the Honda CRF450L / RL & CRF450X

The Twin Air dust cover adds an additional layer of coarse foam over the primary air filter installed in your CRF450L, CRF450RL or CRF450X. This additional layer of foam helps keep the big stuff away from your primary filter and prolong the service interval. This is especially helpful in abnormally dusty conditions or if you are going to be on a prolonged trip and servicing your primary air filter will be difficult.
