The standard angled air filter used in most 4 cycle karting engines. 3-1/2" x 4" with a 20 degree angle. The inside diameter of the mounting flange is 2-7/16". Most OHV kart engines will require an angled air filter!
COLOR MAY VARY.

Did not know if it would work on a duromax 18hp. Worked great and will order more down the road
this filter is stiff and easily dislodged from the carb veloocity stack on my mini bike, the UNI inner filter flexes and stays put in all the time
Needed to open up air flow on my predator, this did the job perfectly
Nice item, construction looks good and happy with my purchase
OUTSTANDING AIR FILTER
