Gas R/C racers can install and remove glow plugs from their engines with ease, speed, and style with the Dynamite Nitro Wrench. The Nitro Wrench has a long, 5-3/4" shank that can reach down into tall engine heat sink heads. It's chrome plated for rust resistance and good looks, and features an indestructible, fuel-proof composite plastic "T" handle. A gas pit box essential.
