NGK SILZKAR7E8S Laser Iridium Spark Plug – 93476
The NGK SILZKAR7E8S is a high-performance Laser Iridium spark plug designed for stable ignition, strong cold starts, and long service life. It uses a fine iridium centre electrode and a platinum-tipped ground electrode for precise, reliable sparking under load. Ideal for modern direct-injection and turbocharged petrol engines, including tuned setups that demand consistent ignition.
Iridium needs less voltage to spark. This helps reduce misfires, improves throttle response, and keeps performance more consistent during repeated hard runs. The plug is pre-gapped and resistor-equipped to control electrical noise that can affect the ECU.
- Fine-wire iridium centre for strong, stable spark and smoother idle
- Platinum ground pad for long life and sustained performance
- Pre-set gap for OE-level reliability and easy installation
