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.
Fine wire iridium tipped center electrode and platinum tipped ground electrode improve ignitability, increase durability and enhance anti fouling capabilities. Special insulator nose configurations improve throttle response. Corrugated ribs prevent flashover. Pure alumina silicate ceramic insulator, provides superior strength and better heat transfer. Copper core aids in heat removal. Triple seals prevent leakage.
Over all fantastic. From the ordering process, to how fast the shipping is and also the customer service. This is why I only shop on GenRacer for my coupe! Keep up the stellar work

I recently purchased the ARK test pipes for my 2010 Hyundai Genesis Coupe 3.8 and must say was the best thing I’ve done aside from from getting my aftermarket exhaust. Sounds louder and drives faster! No hassle, got the pipes within three days. Thank you GenRacer,

Most places just sell parts and when you call them it feels like you are bothering them. My last transaction with GENRACER left nothing to be desired, meaning it could have not been better. I purchased front and rear WHITELINE sway bars, front & rear DBA rotors, and EBC YELLOWSTUFF brake pads. I called just after I ordered the parts because I received an "out of stock" email notification. When I called back to chat with someone *** answered the phone. He couldn't have been more knowledgeable about exactly what I was looking for when it came to the right brake pad for my needs (street/track). Come to find out the pads I picked (DBA's) were not the best pads for my application so im very glad I talked to ***!! I just recently had everything installed, bedded the pads and I am so happy I used GenRacer for my 16 R-Spec Coupe!! Thanks again ***!!!

Order came fast and looks amazing on my car. I did have one problem where one tail light would blink sequentially and the other didn’t. I sent an email late in the day inquiring about it. I wasn’t expecting a response until at least the following day as it was so late. Within an hour they had gotten back to me informing me of a switch on the inside of the housing where you can choose sequential or regular. Sweet! Top notch customer service.
