Why upgrade your coil packs

Ageing coil packs are a common cause of rough idle, hesitation, cold-start issues and poor fuel economy. Refreshing them around every 40,000 to 60,000 miles helps maintain strong, reliable spark and protects engine health. This uprated unit offers a robust solution for daily driving and spirited use.
