The Muc-Off Air FIlter Oil boasts a non-chlorinated, low-viscosity formula and is guaranteed to maximise performance, increase the longevity of your air filter and improve engine life in all off-road weaponry. Our biodegradable foam air filter oil has been developed to provide the highest level of engine protection, even when you're going hard in the toughest of conditions. Our proprietary formulation contains polymeric additives which provide a hyper-tacky surface to resist airborne sand, dust, water, mud and grime. An essential for your motorbike cleaning kit, Muc-Off Air Filter Oil helps to ensure that your engine is protected, whilst maintaining its ability to breathe freely in the most brutal conditions. To use simply apply up to 3.4 fl oz oil and massage into the filter whilst wearing Workshop Gloves or pour the oil into a container and submerge the filter entirely in oil. Ensure that the filter is fully coated on both the inside and outside surfaces the red dye helps to easily identify the protected areas! Once coated, gently squeeze (don't twist!) out any excess oil. Allow the filter oil to evaporate for ten minutes before giving one final gentle squeeze to remove any excess. Once the excess is removed, your foam air filter is ready for reassembling.
