Review on 🔧 CTA Tools 2394 14mm Spark Plug Socket: Professional-grade Performance for Efficient Spark Plug Replacement by Sri Mims

Tool does not work right out of the box for Iridium spark plugs in my 2010 Prius, Denso SC20HR11. The hole in the center of the tool isn't big enough for the top of the spark plug's white ceramic insulator, so it doesn't fit well enough to turn over. I had to take a drill and enlarge the center hole for the tool to fit my car's spark plugs. If anyone knows what it takes to get to the spark plugs in this new Prius, you can understand the frustration I felt at the time. CTA Tools you need to build the best spark plug cartridge. That has a problem.
