Mugen PowerLogo Car Tire Valve Caps - Black (4-Pack)

Pros: - It adds a little style to an otherwise boring wheel valve. - The Mugen name adds a bit of extra street-cred. - Easy enough to screw on without the tightening keyring that's provided. - Acceptable price.

Cons: - Obviously not a genuine Mugen product, but that should be obvious to all buyers.

Other: If you're a fan of Mugen and would like something cheap and cool to add to your car, get these.

Pros: Very good material, nice design, comes with a inner rubber ring that serves to seal the air inside the valve, and the key chain is more useful that it looks: It serves to give torque to avoid been stolen by someone, the valve cap will be to tight that is almost impossible to take out without the keychain or other similar tool. All of then made by good metal.

Cons: Maybe the price, and the key chain style (it doesn't look attractive)

Other: Try to not give SO much torque - it will difficult do disconnect the valve cap, even for you with the keychain...
