These Anti-theft logo valve stem caps set comes with four caps with two durable keys. Each air valve cap has an insert with a Buna O-Ring for a proper airtight seal. The outer logo cap operates independently of the insert. If someone attempts to remove a valve stem cap without the key, the outer logo cap merely spins as if stripped. These Chrome finish Logo Valve Stem Caps add finishing touch to your wheels. Full color, highly detailed logos are permanent, fade-proof, waterproof, and protected by a scratch-resistant polycarbonate coating as used in jet fighter canopies. Precision engineered and plated to show quality specifications. These are made of ABS plastic & do not interfere with the TPMS Tire-pressure monitoring system. This set includes four air valve caps. Logo Valve Caps fit any standard air valve cap stem. This item is Brand New and will be shipped in the original factory packaging.
