Twin Air – Pre-Oiled Air Filters

Twin Air Pre-Oiled Air Filters are the same dual-stage foam filters Twin Air is known for, oiled at the factory and ready to install. Each filter is fully submerged in Twin Air BIO biodegradable foam filter oil and machine-massaged so every pore of the foam is evenly coated. You open the resealable bag and drop it in. No mess, no guesswork, no skipped step before a ride.

Why We Like It:

Hand-oiling a filter is fine if you have time and a clean bench. Pre-oiled is better when you dont. The factory oiling is more consistent than what most riders do at home, and the BIO oil is biodegradable so cleanup later is less of a hazmat situation.

Why Itll Work for You:

If you go through filters quickly between rides or races, pre-oiled saves you a step and a mess every time. The dual-foam design still catches the same range of debris, and the BIO oil washes out cleanly when its time to clean and reuse. PowerFlow versions add a flame-retardant backfire layer, which lets you remove the restrictive stock backfire screen when paired with a Twin Air PowerFlow kit.
