Review on πŸ”§ 14mm & 16mm Spark Plug Socket Thin Wall 12-Point Removal Tool 3/8 inch Square Drive Set for OSOF Optimization by John Frazier

Revainrating 1 out of 5

AVOID THIS PRODUCT! WRONG CONSTRUCTION!

DO NOT BUY THIS PRODUCT! The sockets are too short, the ceramic part of the spark plug touches the top of the socket and enters the ratchet socket and applies the torque to the ceramic body. With almost every spark plug, you break the ceramic. I've had 6 customer car returns to my shop which meant I overtightened and broke them. Each time I've installed the spark plug with a magnet and torqued it with a torque wrench to the correct torque for the vehicles we work with. Further inspection of the outlet sold here revealed a design flaw.

Pros
  • Design
Cons
  • Hard to say
