MMX High Performance Ignition Coil Red for BMW N-Series S-Series Mini - MMR60-0001 - MMX High performance ignition coils for BMW N & S-Series MMX Performance's higher output ignition coils deliver greater energy output, ensuring a stronger and more consistent spark. A simple plug-and-play upgrade over the OE factory coils. Sold individually and available in red, grey and blue. Immediately benefit from a greater energy output and a stronger, more consistent spark. The MMX higher output ignition coils are a direct plug-and-play upgrade from your OE ignition coils. Whether your engine is standard or tuned, it will immediately benefit from the greater energy output and stronger, more consistent spark generated by a set of MMX coils. A coil pack's function is to transform the car battery’s 12-volt output to a much higher voltage. This intensified electrical energy provides a more reliable source for your spark plug to function from, improving engine performance by igniting the fuel and air mixture more efficiently. We've spend a lot of our development time optimising the coil pack's energy levels to ensure operating temperatures are controlled. Over the lifecycle of our coil pack, this thermal management will help to prevent future break down. Replacement is all the more worthwhile on older engines still running the OE coil packs. A new set makes a great preventative maintenance upgrade to avoid the risk of misfires caused as the OE coil packs age and gradually break down. Features Full OE replacement. 10% increase in output energy versus OE. No modifications required. Available in red, grey and blue. Stronger and a more consistent spark. Additional Information Coil packs that generate higher than 10% over OE will overheat and deteriorate over time. We've increased energy output gain to a level that will keep coils as cool as possible for as long as possible. This level of increase represents the 'sweet spot' of the diminishing returns of how much additional energy can benefit the spark strength versus the rapid increase in internal temperatures for long term reliability and performance. Fitting Information Fitment couldn't be easier. These are a simple plug and play replacement. Remove the OE coil packs, replace with our higher output versions.
