HKS Super Fire Racing M Series spark plug 9 for Subaru EJ257 / Vag GEN3 TFSI 2.0-4.0 / Kia Stinger 3.3 / Nissan TB48

HKS Super Fire Racing M Series spark plugs are high quality iridium alloy spark plugs designed to improve ignition performance in tuned and factory engines, increase durability and protect against carbon deposits.

They have anti-vibration properties and are ideal for advanced tuning levels.

The design of the spark plugs consists of:

1) 0.6mm thick center electrode, which reduces voltage requirements, as well as provides durability and improved ignition.

2) an outer electrode with a platinum chip, which contributes to a long service life and improves ignition in conjunction with the central electrode. Thanks to the shortened tip, the necessary space for proper ignition is provided;

3) a short outer electrode, which reduces weight and provides an anti-vibration function and, accordingly, increases the service life;

4) special thermal edge, which reduces the accumulation of carbon.
