It seems like everyone wears a mask at some point or another these days. Whether it's for health reasons or dressing up for Halloween, we all don a face covering from time to time. For the 84-91 Club Car or Columbia Par Car, the Air Filter is the mask your golf cart has to wear to survive. Without it, everything that is in the air around us can get sucked into your engine. Unlike you, your vehicle is not a natural, walking carbon filter, and it can gum up from the debris. Not to mention, the intake is under the seat, exposed to whatever the caddie kicks up as it rolls around. It's like trying to breathe in a dust storm if the air filter gets clogged.This golf cart filter will work for DS models and the older Harley Davidson's that Columbia Par-Car made. It is an aftermarket unit, but it replaces the following OEM numbers. 1012506, 1013379, 29131-71, and 29131-88. Give Buggies Unlimited a call and get one coming today.
