Spark plug compatible with the M12 and Bi-HEX14 shape found in GR Suplar, BMW B engine (B58, B48, B38) vehicles. This product is an excellent replacement for the original product and has a comparable heat value of No. 8 and a heat value of 9 that allows you to feel more secure when tuning. Ruthenium alloy center electrode improves wear resistance. The diameter of the center electrode is 0.02 inches (0.6 mm) to reduce the voltage requirements and improve ignition. (Genuine 0.8mm) ground electrode with platinum alloy tip for improved abrasion resistance and ignition In addition, the length of the ground electrode is shortened to contribute to the strength and durability of the electrode. The ground electrode is built into a copper core to reduce temperature rise in the electrode and increase durability. The MR45XLB is designed to reduce the protrusion dimension into the combustion chamber to reduce the thermal effect of the rising cylinder inside the tuning, and increases durability in high-power vehicles.

I can't say enough good things about VCM Motorsports. I upgraded my suspension with their performance kit, and the difference is night and day. My car handles like a dream now, and the ride quality is fantastic.

John

VCM Motorsports has been my go-to for all my car part needs. Recently purchased a set of brake rotors and pads, and I'm blown away by the performance. The braking power is incredible, and installation was a breeze with their detailed instructions.

Mike

I upgraded my exhaust system with VCM Motorsports, and I couldn't be happier. The sound is perfect—deep and aggressive without being obnoxious. The quality of the materials is outstanding, and the fitment was spot on.

Alex

I bought a set of performance tires from VCM Motorsports, and they have transformed my driving experience. The grip and handling are phenomenal, and I feel much more confident on the road. The price was competitive, and the tires were delivered quickly.

Emily

VCM Motorsports is the best in the business! I recently installed one of their turbocharger kits, and the power gains are unbelievable. My car is so much faster and more responsive now. The kit came with everything needed for installation, and the instructions were very clear.
