Air valve caps designed to discharge and remove static electricity from tires and wheels! We've researched and tested these, aiming for effects similar to Orbitron's titanium air valve caps and Geki Quantum's Ultimate Valve. They work well with static removal goods like carbon discharge cables and reactors. We've tested them on various vehicles(^^)/ We've made numerous improvements and updates to enhance the effect, and the current version has been road-tested on a Mercedes-Benz G-Class to ensure effectiveness even for heavy vehicles and SUVs♪ For those who are experts in static removal tuning, static removal maniacs, or static removal fanatics, you may already have various reactors and EDLCs (capacitors) installed. As a static removal fairy myself, I've also repeatedly confirmed the compatibility with my own car. Those who love static removal tuning will likely find it even more enjoyable with the synergistic effect, but even just the static removal air valve caps alone should be plenty of fun as a first-time static removal tune! The set includes: ・Static electricity removal valve caps for one vehicle (4 pieces). Antistatic system Static Removal Craftsman Static Removal Air Valve Caps Similar to discharge nuts for tire valves, Geki Quantum Ultimate Valve, Repton Power Valve, and air valve caps from manufacturers like Orbitron, HADOO, NGC Japan, and SEV, these are original creations, but we've made them to be just as effective. If you like these, you can step up to the high-end products from various manufacturers and enjoy comparing them. Installation is as simple as replacing the valve caps currently on your vehicle. Before installation, clean the vehicle's screw threads with an alcohol wipe to remove any dirt. Clean the part that contacts the discharge section to maximize the effect. Then, simply tighten the discharge valve cap lightly until it stops. The effect stabilizes after about 1 to 2 days after installation. Please wait for the effect to stabilize without taking the initial feeling at face value.
