Primary Uses & Benefits
-
Grip & Porcelain Protection: Features an internal rubber grommet that firmly holds the spark plug insulator, preventing the plug from dropping down into deep cylinder head wells during removal and protecting the ceramic body from cracking.
-
Deep Well Reach: Engineered with a long-reach body to easily fit into deep-seated spark plug tubes common in DOHC and modern automotive engines.
-
Torque & Fitment: High-grade Cr-V construction handles standard manual torque application using 1/2″ drive ratchets, breaker bars, extension bars, or torque wrenches without slipping or stripping.
