Upgrade your 4-stroke engine with a Twin Air aluminum oil filter cap that replaces the standard cover with a stronger, better-cooling design. Black anodized finish adds durability and a clean factory look.
Improve durability and cooling where it matters. The Twin Air Aluminum Oil Filter Cap is a direct replacement for the standard oil filter cap on current-model 4-stroke bikes. By switching to a robust aluminum, black anodized cover with integrated cooling fins, you get a more resilient component that also helps shed heat—ideal for hard riding, hot conditions, and demanding service intervals.
This upgrade is a smart choice if you want a stronger, better-looking oil filter cover while keeping installation simple and OEM-like. The bolt-on mounting style makes it easy to fit during routine maintenance or an oil change.
