The HKS Super Fire Racing MR45XLZ is a premium, long reach M12 spark plug engineered for high-boost, tuned, Gasoline Direct Injection (GDI) engines.  They feature a No. 9 heat range (NGK equivalent) and advanced materials to ensure reliable ignition and consistent engine performance 
 
These plugs come pre-gapped to .030" from HKS which is suitable for use out of the box but we suggest closing the gap down to .028 for mildly modified N's to .022 for high boost/high power applications
 
Key Features & Technology
  • Ruthenium Alloy Center Electrode: Combines exceptional durability with a reduced voltage requirement, which leads to improved ignition performance and better fuel burn. 
  • Platinum Square Chip Outer Electrode: Grooved and shaped to improve ignitability, combustion speed, and to reduce overall weight, providing anti-vibration durability. 
  • Protruding Electrode Design: Specially designed to aid in combustion swirl and efficiently manage the high fuel pressures commonly found in GDI engines. 
  • Thermal Edge & Plating: Features advanced heat transfer/insulation coatings and anti-corrosion finishes to prevent carbon buildup and resist extreme racing environments.
  • Brass Terminal: Ensures a firm, secure fitment to the ignition coil-pack or plug wire. 

Overall Fantastic

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

Awesome Service

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,

Simply the Best Service

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 ***!!!

So Awesome

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.
