Review on 🔧 WINTOOLS 26pc Spark Plug Thread Repair Kit M14 x 1.25 with Durable Metal Case - Fix Spark Plug Threads with Ease! by Larry Morris

Had to use a 3/8" to 6" extension to get just enough to screw the engine spark plug boot back in. Also make sure you fill the slots with extra sticky grease to ensure no metal shavings get into the cylinder head, not the end of the world if you do just flip the engine over before putting the spark plug in the cylinder use what you have just been working on. I'm a little more than skeptical about these threaded inserts, unlike helicoids and other similar inserts other than threading, they don't have teeth on top. I feel like they are crucial due to the last step permanently locking in the threads Place for a good thing not even in this set, there should be a tool like a rod or pin that inflates when Hitting them with a hammer, or a hammer that flares out the head of the insert and drives its teeth into the spark plug well or cylinder constantly stuffing holes in the walls, so while the kit really works I don't recommend it's very useful if it's about cars.
