NGK Iridium IX Spark Plugs - BR7HIX - 7067

The Iridium IX spark plug features a fine-tipped iridium center electrode that provides superior ignitability, leading to better combustion, improved engine performance, and longer service life.

No, it is designed for specific petrol engines. Always verify compatibility with your vehicle's make, model, and engine specifications before purchasing or installing.

This refers to the resistor built into the spark plug, which helps to suppress radio frequency interference generated by the spark, preventing it from affecting other electronic systems in your vehicle.

While primarily noted for CNG/LPG, it can be used with standard gasoline if compatible with your engine specifications. However, its optimal benefits are often seen with specific fuel types or high-performance applications.

Iridium spark plugs typically offer a longer lifespan than conventional plugs. Refer to your vehicle's maintenance schedule for recommended replacement intervals, which are generally much longer than standard plugs.

The BR7HIX has a 12.7mm thread length, a 14mm outer thread diameter, requires a 20.8mm hex nut size, and has a 1.5mm spark projection.

Check if the spark plug is properly seated and tightened. Ensure the spark plug wires are securely connected. Verify the correct spark plug type is installed for your engine.

Ensure the spark plug is clean and free from fouling. Check the fuel mixture and ignition system for proper operation. Confirm the spark plug is the correct heat range for your engine.

Inspect spark plugs for wear or damage. Ensure correct installation and torque. Consider replacing other ignition components if they are old.
