Product Details

The HKS 50003-M45HL is a high-performance M-Series Super Fire Racing spark plug featuring advanced iridium alloy construction designed for improved ignition performance, durability, and anti-carbon buildup under high load conditions. Sold individually.

Key Features:

  • 0.6mm iridium alloy center electrode for precise spark delivery
  • Outer electrode with platinum chip for enhanced durability
  • Short-type outer electrode design provides superior anti-vibration characteristics
  • Thermal edge technology optimizes heat dissipation
  • Spark support gap ensures consistent ignition
  • Nickel-coated housing prevents premature deterioration
  • High melting point of 2454°C withstands extreme compression and minor detonation

The M-Series spark plugs utilize iridium alloy for its exceptional durability and reliability. Despite the narrow electrode core, the iridium construction maintains extended service life without compromise. The advanced materials and design make these plugs ideal for tuned engines operating under demanding conditions while maintaining reliable cold starts and smooth idle characteristics. Available in colder heat ranges (7 and up) for various performance applications.

They have the best prices and fast shipping too.

Wow!! I came across Autoplicity while searching for a fuel pump for my Trans-Am. Not only did they have the cheapest price for the part, but they also had extremely reasonable shipping cost. Most websites claim to have free shipping but it seemed the cost of shipping was added to the cost of their part. Then I find out my order was processed and shipped within one business day!! I'll definately be bookmarking Autoplicity's home page!! Thanks!!

Great price and fast shipping!

Easy to use website.

Best price I could find! Great customer service kept me informed through the whole order process to insure acuracy since it was being sent directly from the manufacture. Recieved my order in good time, right parts and no damage. Overall very satisfied and will be doing business again in the future.

Very competitive low prices and great product selection. Will definitely look to this vendor when purchasing automotive parts in the future.

Great prices and FAST shipping!! Definitely will buy products here again!

Although there was a mix up with the shipping on my order customer service was helpful and expedited the solution and made it worth my trouble. I will be keeping Autoplicity in mind for any other parts I might need for my Jeep.
