Stinger spark plugs

Great upgrade to prevent sparkplug failure.
Had factory spark plugs fail at 65K kms. These are a great improvement thus far especially when included with the Race chip upgrade.
Thanks Cherry - great service and fast shipping.


I installed these today with MSD COILS and couldn’t be any happier can runs and idles much smoother has also made cold start better and smoother too still running a stock tune would see more benefits over a retune but then again really happy 👍

Excellent Modification Cerato GT

Bought these in conjunction with the RS chip from Cherry, very high quality product would highly recommend if getting a race chip installed. Would recommend speaking to Tristan as he is very passionate about cars and will set you on your path to modifying your vehicle

Hks Spark Plugs. CERATO GT

Certainly make a difference up top. Few more mods and a tune should get the potential out of these upgraded plugs. Smoother idol on cold start.
