Best plug I haveever used
It really brought the rest of my mods to life
At a NGK Heat Range 9 equivalent, these plugs will ensure there is less heat when you are making more power. We highly recommend this plug when running our Tunes!
Here is a good article on Spark Plug basics by NGK.
HKS Plugs ignite faster for the best fuel efficiency and the best performance in all situations and environments. It is very important to provide safe and stable ignition for the engine to perform at maximum power. HKS Super Fire Racing plug is the best plug for extreme racing driving and also works well for normal tunes.

Packaging was a bit shoddy but the khs packaging of each spark plug was good enough that it survived rough handling. pre gapped for your enjoyment :)

I bought these with my Stage 1 High Torque spare ECU tune.
I purchased a set of these spark plugs for my 2017 Hyundai Elantra Sport, as I have been changing out my spark plugs since I purchased the car. I decided to try these, upon getting them and installing them with a light torque set as I always do ( 5-7 lbs) before I fully tighten them down. One of them stripped on the 4th cylinder entry hole! How great, so now I had to call a friend to come help tow the car to a shop and the shop states that my car has metal pieces in the engine and its locked up. OHHHH GREAT, so now they state that some of the material from stripped plug may have entered into the engine :/. So now my car is at a dealership, thank god for warranty but I would not trust these sparks. Just go with the generic or dealership sold plugs.
