It's a civic specific wrench. Use it on the next $500 civic with 350000 kms, a $5000 body kit, and 19" rims. Pop the hood, laugh at the engine about to die, (especially if the rings are shot from being revved up at stoplights) and smash the driver with it. Goes double if they have 1000's of watts of subwoofers in the trunk, or a tailpipe bigger than 2".
