Show original supplier description

This ignition coil is designed to deliver a 10% stronger spark compared to OEM units, helping to maintain peak engine performance without the need for any ECU remapping or tuning. This coil is also explicitly compatible with 2020+ Toyota Supra models (B46/B58 engines) and 2014+ F5X Mini Cooper vehicles. The product is sold individually, and customers must ensure they order the correct quantity based on their specific engine's cylinder count. It is designed to directly replace OE part numbers: 12138643360, 12138678438, 12138647463, and 12137619385.
