We recognize the critical role that spark plugs play in engine performance. Laser iridium spark plugs, such as the NGK IFR5E-11, are designed to provide superior ignitability and long service life. These spark plugs feature fine wire electrodes that ensure precise firing, while the iridium and platinum materials guarantee durability.
Choosing a spark plug with the correct heat range is essential for preventing engine issues. The heat range cross-reference is a vital tool to match the spark plug to the engine’s temperature demands, ensuring consistent performance without overheating or pre-ignition.

The platinum-tipped electrode is a hallmark of quality in spark plugs. This feature extends the lifespan of the spark plug, and in replacements for the NGK IFR5E-11, it ensures that the spark plug maintains its sharp firing edge over many miles of use.
The resistor value in a spark plug is an often overlooked but critical specification. It controls the electrical noise that can interfere with vehicle electronics. NGK spark plugs are engineered with an optimal resistor value to maintain the integrity of the vehicle’s electronic systems while delivering reliable performance.
Understanding Spark Plug Torque and Its Importance
Correct spark plug torque is crucial for installation. It ensures a proper seal and heat transfer. Over or under-tightening can lead to various engine issues.
We provide detailed torque specifications for cast iron or aluminum engine heads to ensure that your NGK iridium spark plug is installed to the manufacturer’s exacting standards.
Q: What are the benefits of NGK Laser Iridium spark plugs?
A: NGK Laser Iridium spark plugs offer the best in longevity and performance, thanks to their fine wire iridium center and platinum-tipped electrodes. They deliver superior ignitability and consistent performance.
Q: How often should I replace my spark plugs?
A: The longevity of your spark plugs can vary depending on their type and your vehicle’s specifications. For example, NGK Laser Iridium spark plugs have an extended lifespan due to their durable materials.
