HKS Super Fire Racing MR45HLZ Spark Plugs (Heat Range 9) - Pack of 10
$330.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
HKS Super Fire Racing MR45HLZ spark plugs are engineered to withstand the extreme cylinder pressures and temperatures of high-performance and tuned engines. These plugs utilize a specialized iridium alloy center electrode to provide superior ignition reliability, improved durability, and a consistent spark under heavy load. The MR45HLZ is designed for modern engines requiring a long-reach shell to ensure optimal spark positioning within the combustion chamber.
With an HKS heat range of 45 (equivalent to an NGK 9), these plugs offer the enhanced heat dissipation necessary for forced induction or high-RPM applications where controlling pre-ignition is critical. Each plug is built to tight tolerances to ensure proper clearance and electrical resistance for consistent engine timing and power delivery.
