The Yamaha Foam Pre-Filter is a magical thing. It does not matter which one you are talking about either. Whether it be the air filter or fuel filters, they both pull off a pretty fantastic job. You will notice we did not list an oil filter. Yamaha has not made a cart that takes an oil filter. This is a fun trick you can play on a friend the next time they help you with some maintenance. Would you mind giving them the job of taking the old oil filter off and tell them it's hard to find? It will provide hours of entertainment. Just be sure to duck the wrench they throw at you when they figure out it's a drain and fill system.This golf cart pre-filter installs on the outside of the air filter. It allows you to extend the life of that air filter by blocking a good bit of the containment from harming the paper insides. Call Buggies Unlimited and get one ordered today.
