Shockproof TPU Spark Plug Case | Waterproof M14 Holder

Your Trail Insurance Against a Fouled Plug

Never let a damaged spare end your ride. In Hard Enduro, a spare spark plug is useless if its ceramic insulator is cracked or its gap is filled with grit. Our Shockproof TPU Spark Plug Case is engineered to keep your backup plug in factory-perfect condition, no matter how extreme the terrain or how many times you drop your tool bag.

Engineered for the Extremes:

• Virtually Indestructible (TPU): Unlike brittle injection-molded plastic, our cases are 3D-printed from High-Grade TPU (Thermoplastic Polyurethane). This rubberized material is incredibly flexible, impact-resistant, and won’t crack under pressure.

• Total Electrode Protection: The threaded design creates a weather-resistant seal that locks out moisture, mud, and fine dust. Your electrode stays clean, dry, and ready to spark instantly.

• Shock-Absorbing Internal Design: The TPU acts as a "silencer" and cushion, absorbing vibrations and heavy impacts. It prevents the fragile ceramic insulator from cracking even if crushed in a dense fender bag.

• Universal M14 Compatibility: Precision-engineered for all standard M14 x 1.25 threads. This is the go-to size for almost all modern 2-stroke and 4-stroke enduro engines.

Technical Specifications

Why Hard Enduro Riders Choose TPU Over Plastic:

Standard plastic holders are "one-hit wonders"—they rattle, they crack, and they offer zero vibration damping. Our FFF-printed TPU case is a professional-grade tool. It doesn't just hold the plug; it armors it. It is "bulletproof" gear for riders who take their spares and their race finishes seriously.

Fits All Major Brands:

Perfect for KTM, Husqvarna, GasGas, Beta, Rieju, and Sherco owners who carry spare plugs in their hydration packs, fender bags, or tool wraps.
