Ignitionability, durability, anti-insulation are all reinforced. HKS has made the best plug for both tuning engines and stock engines.

Features:

This spark plug is the M12 and Bi-HEX14 shape that is compatible with the GR Supra and BMW B series engine (G58, B48, and B38) vehicles.
We are offering NGK heart range 8 equivalent spark plug, which is ideal for replacing genuine products, and NGK 9 equivalent spark plug, which provide a higher grade of peace of mind with tuned car.
Durability is ensured by alloying the central electrode with ruthenium
The center electrode diameter set at 0.6mm reduces the required voltage and improves ignition performance. (Stock: 0.8mm)
Ground electrode with platinum alloy tip improves durability and ignitability. Shortened ground electrode length contributes to electode strength and durability
The ground electrode contains a copper core to suppress temperature rise of the electrode and improve durability
The MR45XLB is designed to minimize the dimensions protruding into the combustion chamber, making it less susceptible to the heat inside the cylinder, which rises under tuning, and further improving durability in high-output vehicles.
