A must for modified cars...

Was experiencing periodic boost cuts on my stock spark plugs, presumably from the extra heat and load from my RaceChip S and other mods, and these spark plugs resolved the issue instantly. A must have if you are planning on modifying or tuning your Hyundai/Kia 1.6T as they are cooler and can take more load. Tristan provided a quick turnaround time and has been amazing in supplying quality parts. 10/10 recommend!!

Fixed my Idle Issue

Got these plugs due to a having a slight miss at idle from running the Race Chip GTS on my 2019 GT Cerato, was sceptical at first that these plugs would fix it, but was happily surprised as it now idles perfect. I would highly recommend using them when running a Racechip.

Making more power possible

Installed these in M N Line which allowed for a retune. With these plugs in the car is now able to make more power and hold consistent boost in the higher RPM ranges.
