NGK DILZKAR7C11H Laser Iridium Spark Plug
The NGK DILZKAR7C11H is a premium, long-life spark plug designed for clean ignition under everyday driving and high load. It uses a fine iridium centre tip and a platinum pad on the ground electrode to keep the spark strong and stable, with minimal wear over time.
This plug helps cold starts, smooth idle, and consistent performance at higher RPM or boost. Heat range 7 provides reliable knock resistance and thermal control in many modern petrol engines.
Use as a like-for-like replacement only. Always confirm fitment with the vehicle lookup or the Vehicle Fitment tab.
- Strong spark with low voltage demand for reliable ignition
- Long service life from iridium and platinum laser-welded tips
