The NGK R7282-10 (NGK #2000) is a true NGK Racing Series plug built for extreme combustion environments in KZ shifter karts, Mod Moto, and Open 125cc race engines.
Key Features: 14mm thread • 19mm (3/4") reach • 1.25mm pitch • 5/8" (16mm) hex • Heat range 10 • 5k resistor • Solid terminal • Pre-set ~0.6mm (.024") gap
Electrode Design: 0.6mm fine-wire iridium center electrode with platinum slant ground strap for improved flame kernel exposure and combustion stability at sustained high RPM. Engineered for high compression and aggressive ignition timing — not a street plug.
Performance Benefits: Stronger spark under extreme cylinder pressure • Improved throttle response • Reduced misfire at peak RPM • Greater detonation resistance • Superior anti-fouling vs. standard nickel plugs
Fitment: Common in TM KZ R1/R2/R3, CR125, YZ125, Mod Moto, and Open 125cc builds. Often used as the short alternative to R7376 when clearance is tight.
NOTE: NGK TRS1225 or PVL SHORT cap required

NGK 10 Heat Range Spark Plug Comparison
| Plug | Electrode | Ground | Ignition Strength | Longevity | Notes |
|---|---|---|---|---|---|
| R7282-10 | Iridium fine wire | Platinum slant | Highest (race-focused) | High | True racing plug, maximum stability under extreme RPM/pressure |
| R7376-10 | Iridium fine wire | Platinum slant | High | High | Very similar to R7282-10, uses standard plug cap, lower cost |
| BR10EIX | Iridium fine wire | Nickel | Good | Longest | Best street/dual use; iridium life + broad compatibility |
| BR10EG | Nickel | Nickel | Moderate | Shortest | Budget racing plug; older tech, wears faster |
