Description

Product Overview

The MTRPS Back Tap Spark Plug Thread Repair Tool is a precision‑engineered device designed to revive damaged or stripped spark plug threads. Featuring a robust steel construction, the tool offers exceptional hardness and longevity, ensuring consistent performance even after repeated use. Its back‑tap design actively pushes metal shavings away from the cylinder chamber, maintaining engine cleanliness during the repair process. Sized at 5.23 inches in length with an M14×1.25 thread, the tool fits a wide range of engine types, providing a versatile solution for automotive professionals and hobbyists alike.

Usage

This tool excels in environments where spark plug threads have become cross‑threaded, worn, or broken. Ideal for routine engine rebuilds, performance upgrades, and emergency repairs, it allows users to insert the tool through the spark plug hole, apply lubricant, and turn clockwise to re‑cut the thread to its original profile. After each forward turn, a few reverse rotations clear debris, ensuring a smooth finish. Suitable for gasoline, diesel, and hybrid engines, the Back Tap Tool is a practical addition to any garage or workshop.

FAQ

Can this tool be used on all spark plug sizes?

The Back Tap Tool is specifically sized for M14×1.25 threads, which are common in many automotive engines. For other thread sizes, MTRPS offers additional models.

Do I need special lubricant?

A light penetrating oil or engine oil works well. Apply a small amount to the thread before using the tool to ensure smooth operation and prevent galling.

How many times can I reuse the tool?

Thanks to its hardened steel construction, the tool can be used repeatedly without loss of cutting ability, provided it is kept clean and stored dry.

Will the back‑tap design damage the cylinder head?

No. The back‑tap feature is designed to push debris away from the chamber, not to impact the head. When used correctly, it safely restores threads without harming surrounding components.
