Questions & Answers

Is this a genuine original part?

This is a premium quality aftermarket replacement part from the 4Drive range, manufactured by NGK to meet or exceed original equipment (OE) standards for fitment and performance.

How do I know if it is compatible?

We recommend checking the SKU/MPN (IFR8H11 / 5068) and the OEM Cross Reference list provided above. If your original part number matches any of these, it is a guaranteed fit.

What makes the Laser Iridium range better than standard plugs?

The iridium-alloy center electrode is 6 times harder than platinum and has an extremely high melting point, which translates to a more stable spark, improved throttle response, and superior anti-fouling characteristics compared to standard nickel or platinum plugs.
