Walker Products ThunderSarp Ignition Coil

The Walker Products ThunderSpark Ignition Coil (also called a spark coil) is a direct-fit replacement for the ignition system. It works as a transformer. It takes the 12 volts from the vehicle's electrical system and steps it up to the tens of thousands of volts needed to fire the spark plug. That spark ignites the air-fuel mixture in each cylinder, which supports smooth running, efficient combustion and dependable starting.

Key Features:

• OE-style fit and function: Designed as a direct-fit replacement for fast, straightforward installation.
• OE replacement quality: Built to meet or exceed original equipment specifications for performance and durability.
• Heat and vibration resistant: Durable materials and housings stand up to under-hood heat and vibration.
• Quality construction: Windings and insulation are made for consistent spark output and long service life.
• Reliable spark delivery: Gives consistent high-voltage output for efficient combustion.

A worn or failing ignition coil can cause misfires, rough idle, hard starting and poor fuel economy. Replacing it with a ThunderSpark coil helps restore proper engine performance and ignition reliability. Walker Products is a long-established supplier of ignition and emission control components.
