Oval shaped all black air filter with red foam. Fits Honda CB750 and others. Comes with black mounting clamp. Sold individually.

Keep in mind, for the bike to run smoothly, you may need to install larger jets and make other adjustments to match the higher air flow. The rubber mounts are flexible and can be mounted on 38mm and 40mm carburetor flanges.

Too long to clear the frame on the CB500 & CB550 models.

IMPORTANT: Be sure to measure your carburetor prior to purchase. Also measure how much room you have between the carburetor and the frame or any side covers. Use the dimensions below to see if these will work on your bike. Just because the filters fit the carbs doesn't mean they'll fit in the bike without some obstruction.
