The Royal Enfield Bullet 350 / 500 Continental GT535 Genuine Oil Filter & O ring set is a classic part made of paper, designed specifically for dual sport motorcycles and street motorcycles. It includes a gasket and is manufactured in India by Royal Enfield. This oil filter is not a performance part and is not universally fitting, making it a genuine and reliable choice for Royal Enfield enthusiasts looking to maintain their motorcycle's engine with authentic components.
