The expansion of MOTORTECH’s state-of-the-art ignition controllers is driven by the latest developments in modern spark-ignited gas engines. The operation of these high-performance engines with advanced compression rates and very efficient lean-burn combustion systems requires much higher voltages to allow perfect and effective combustion. MHP spark plugs are designed to meet the requirements, both of modern and common engine developments, and reliably deliver the highest voltages and thus a strong spark down into the combustion chamber. The J-type electrode design with IRIDIUM alloy discs on the center and ground electrodes provides reliable combustion and increased spark plug life and helps to reduce service costs due less spark plug changes.
