NGK ILKAR7D6G Laser Iridium Spark Plug (Stock No. 93607)
This NGK Laser Iridium plug delivers a strong, consistent spark for cleaner combustion and reliable performance. It improves cold starts, helps maintain smooth idle, and resists misfire under load. The iridium centre electrode and platinum-tipped ground reduce wear, so the gap stays stable for longer service life with less maintenance.
- Sharper spark for better throttle response and efficiency
- Stable at high temperatures and pressures in turbo or high-compression engines
- Long service life thanks to iridium and platinum wear surfaces
