상품 특징

• 2-Pack Covers All Bore Depths - M12x1.25 Spark Plug Thread Repair Without Removing The Cylinder Head - Stripped or fouled 12mm spark plug threads? This Back-Tap Spark Plug Thread Repair Tool 2-pack includes both a 5.27" short version and a 10.3" long version, engineered specifically for M12×1.25 thread pitch. The short tool handles standard shallow-bore engines with limited clearance above the spark plug hole; the long tool reaches deep spark plug bores found on larger-displacement and performance engines. One purchase covers every M12×1.25 application — no cylinder head removal, no helicoil inserts, no machine shop required.
• Debris Exits With The Tool - Zero Metal Shavings Left In The Cylinder - The biggest risk with conventional thread chasers is metal debris falling into the combustion chamber, causing catastrophic engine damage. Our Back-Tap Style design works in reverse: as the tool is pulled outward, it captures and carries all metal shavings and debris out of the bore with it. Apply a small amount of grease to the threading area before use to maximize debris adhesion. Your engine stays protected every time.
• Collapsible Design Enters The Bore, Expands Inside, And Repairs Threads From The Bottom Up - Standard thread taps cut from the top down, pushing metal debris deeper into the engine. This tool works differently: it collapses to fit through the M2×1.25 spark plug opening and pass into the combustion chamber. Once inside, the repair zone expands and locks onto the last intact threads at the base of the bore. As the tool is drawn back upward, it re-engages and restores each damaged thread in sequence - working from clean to stripped, inside out — in one smooth, controlled motion with no debris pushed downward.
• Extreme Hardness - Built To Rethreading Hardness Demands, Made to Last - Spark plug thread repair demands a tool harder than the aluminum cylinder head it's cutting into. This Back-Tap tool is manufactured to extreme hardness specifications specifically engineered to meet and exceed the demands of repetitive thread cutting in engine-grade aluminum. Unlike softer tools that dull after a single use, this tool maintains cutting precision across multiple repair jobs - for professional shops and serious DIYers alike.
• Skip The Traditional Thread Taps. Skip The Machine Shop. Get Back On The Road. - Traditional M12×1.25 spark plug thread repair means wrestling with Heli-Coil style insert kits, or pulling the cylinder head entirely. The Back-Tap eliminates both. This 2-pack gives you the right tool regardless of bore depth — use the 5.27" on compact, shallow-bore engines, and the 10.3" wherever a standard-length tool can't reach. M12×1.25 threads are common on smaller-displacement gasoline engines and many motorcycle, ATV, and powersports applications, compatible with Yamaha, Kawasaki, Suzuki, Honda, and BMW.
• Package Include: 2 pcs M12*1.25 (1pcs 5.27" short version and a 10.3" long version) spark plug thread repair tools.
