NGK DCPR7EIX Iridium IX Spark Plug – 6046
The NGK DCPR7EIX is a fine-wire iridium spark plug designed for strong ignition and long life. It gives a clean, reliable spark under load. It helps cold starts, idle quality, and throttle response. It also resists fouling better than standard copper plugs.
Use it as a performance-focused replacement where DCPR7EIX is specified. It suits many modern motorcycles, scooters and ATVs that require an M12 projected resistor plug in NGK heat range 7. Always confirm fitment with the vehicle lookup or check the Vehicle Fitment tab.
- Fine-wire iridium centre electrode for a strong spark and stable combustion
- Projected tip helps mixture ignite efficiently
- Resistor design reduces electrical interference with ECU and electronics
- Nickel ground electrode with tapered cut for consistent flame kernel
- Trivalent plating on the shell to resist corrosion and seizing
Check and set the gap to your vehicle spec. Torque to the manufacturer’s value. Do not use anti-seize on NGK plated threads.

Why choose this plug
Iridium holds its sharp edge longer than copper. That keeps the spark strong over more miles. It can help maintain power and economy between services. For lightly tuned engines, it supports clean combustion without needing a colder heat range.
The price displayed is for a single plug, please add the desired amount to your basket.
