Powerbuilt’s 14mm Back Tap is a precision tool built to salvage spark plug threads that have become damaged or fouled. Designed for motorcycle and automotive maintenance, it works through the spark plug hole, drawing debris up and out as it repairs, helping you keep engines running smoothly without abrupt downtime.

Effortless repair through the spark plug hole

Key benefits you may notice in practice include:

  • Collapsible design enables insertion through the spark plug hole and seating into the chamber, expanding the threaded area as it advances
  • As the tool is drawn up, debris is carried out with it rather than falling into the cylinder
  • It threads into the clean grooves to repair damaged threads as it passes, reducing the need for inserts
  • Saves time by repairing fouled threads without removing the cylinder head
  • Built to meet ANSI standards and crafted from heat treated 4118 steel for durability in field settings

Durability and precision you can rely on

In practical use, this tool supports a controlled, straight repair sequence when access is tight and downtime matters. It targets 14 mm spark plug threads commonly found in motorcycles and small engines, aiming to restore thread integrity without extensive disassembly. The design minimizes disturbance to surrounding components while prioritizing a clean, functional repair.

  • Collapsible engagement through the plug hole preserves surrounding components
  • Durable construction supports repetitive use without compromising performance

What to know before you use it

Notes on use and compatibility help set expectations. While designed for 14 mm spark plug threads, consult your service manual for precise limits and procedures. This tool is part of a maintenance workflow focused on reliable thread restoration rather than a guaranteed outcome.
