Frequently Asked Questions

Q: How do I know if the 2-7/16" ID will fit my carburetor?

A: You should measure the outer diameter of your carburetor's intake bell. The 2-7/16" ID is designed to provide a snug, secure fit on standard racing carburetors of that size. Always ensure your intake surface is clean before sliding the filter on.

Q: Why choose an angled air filter over a straight one?

A: The angled design is specifically engineered for karting setups where space is limited. It allows you to route the filter away from engine components or chassis bars, helping you pull in cooler, cleaner air for better combustion efficiency.

Q: How should I clean and maintain this fabric air filter?

A: To maintain performance, gently tap the filter to remove loose track sand and debris. If it becomes heavily soiled, use a mild cleaning solution or compressed air from the inside out. Ensure the filter is completely dry before reinstalling it on your engine.

Q: Do I need a specific clamp to install this filter?

A: Yes, a secure clamp is essential to prevent the filter from vibrating loose during high-RPM racing. We recommend using a high-quality hose clamp to ensure an airtight seal between the filter neck and the carburetor.
