You are viewing a BRAND NEW IRI Series Iridium Spark Plug by NGK.
What is an iridium spark plug?
-High-output, high-rev sports car engines require a spark plug that is able to withstand the loads generated by high power engines and can guarantee reliable ignition.
Selecting for heat
-Based on data taken under the harsh conditions at races and rallies, NGK spark plugs exhibit powerful, stable, and consistent results even under high-load, high-speed driving conditions, so that your engine can accelerate smoothly. We make available five heat value types to best suit your engine performance characteristics, giving you a choice of the optimum heat value. (The higher the heat value, the faster the plug radiates heat and cools.)
- A high plug number doesn't mean you'll be able to go faster. If the plug number is too high, the engine may hesitate at low revs. If it is too low, pick up will worsen. So, we recommend you choose a plug that best suits your driving patterns.
Benefits to the NGK IRI Series Spark Plug:
-Excellent for powerful, sporty cars
-Improves output to achieve powerful acceleration.
-Improves fuel economy and reduces pollution.
-Stabilizes engine combustion
