HKS MR-Series "Super Fire" Ruthenium Plugs

Planning on getting more power out of your Hyundai or Kia by installing a JB4, RaceChip, or tuning your ECU? You'll want to upgrade your spark plugs to make the most of your factory ignition system!

This new series of plugs inherits the best from the existing M series, however it now features a Ruthenium Alloy Electrode to provide a reliable spark for all vehicles, including vehicles with increased boost or tuned vehicles.

On top of extended lifetime, the use of Ruthenium alloy allows a better fuel burn, resulting in quicker throttle response, smoother idle and better cold starts (especially noticeable on the NGK9 range plugs vs. the existing M series)

The two options are:

NGK8 for stock, or lightly tuned engines - these are a stock-replacement upgrade for the 1.6T in the i30 and Cerato GT
NGK9 are for cars that are modified, tuned, or are being pushed harder than stock. Any increase of 50HP over factory generally requires a 1-heat-range colder drop in plugs. These are 1 range colder than stock for the 1.6T and 2.0T in the i30N, N-Line, and Cerato GT

Note: These plugs are only suitable for the 1.6T and 2.0T engines, they aren't suitable for the Stinger's 3.3TT

All orders are packaged at our Hornsby workshop. In general, handling times are between 24-48 hours.

We primarily send orders via Australia Post. For heavier/bulkier items that cannot be sent with Australia Post, we use a courier service.

Typically shipping ETAs can be anywhere from 2-5 days from the date of shipping. The timings are dependant on where you live and the current COVID impacts.

If your item has not yet shipped and you have changed your mind, you will still be liable for a 10% cancellation fee to cover website fees, charges, and the time taken to process your refund. This fee can be reduced or waived at the discretion of Cherry Tuning management.
