Product Details
✓Fix stripped threads: The thread repair tool kit is a tool for spark plug repair. This tool does not require any difficult operation and is suitable for everyone. Allows you to cut threads to fix a stripped and damaged 14mm spark plug threaded hole port and repair plug configurations in aluminum heads
✓Easy to use: Rotate the crankshaft to make sure no ports/valves are open, use the tap to install new threads, choose the proper depth of insert, and screw it firmly into the newly tapped head; Apply grease on the tap to help catch any metal shavings (rather than letting them drop into the cylinder) and back out the tap out every half turn to every whole turn to clean the metal shavings from the tap. Using grease is essential to prevent metal shavings from falling into the cylinder and damaging your engine
✓Wide compatibility: This repair kit is compatible with BMW, Nissan, and Toyota engines to clean and rethread damaged spark plug ports. No cylinder head removal is required, provided that the head is aluminum, the spark plug hole is straight, and there is sufficient clearance to turn the tap with a ratchet or wrench
✓Specifications: Chrome Steel / 40Cr steel. Tap Size: 73 * 21mm / 2.87'' * 0.827''. Spark Plug Insert Thread Diameter: 15.6mm / 0.614''. Spark Plug Insert Thread Pitch: 1.25mm / 0.049''. Thread Inserts Length: 11mm (0.43inch), 13.2mm(0.52inch), 17.8mm (0.7inch). Tap Length:approx.73mm (2.87inch)
✓Package Included: 1 x Re-thread Tap, 4 x Spark Plug Inserts. It has two repair tool thread lengths of 0.43in, one repair tool thread lengths of 0.52in and 0.7in. Tap is tapered to allow the tip to fit and rethread the hole in order for the coil to fit
