ThunderSpark® Coils & Coil Boots
The Ignition Coil, or Spark Coil, functions as a transformer that converts a vehicle’s 12-volt power to the 25-30,000 volts needed for combustion. Walker Product’s Ignition Coil Program for domestic and import vehicles consists of Ignition Coil Packs, Coil-on-Plug Ignition Coils, Pencil Ignition Coils and Cassette Ignition Coils. We cover a broad range of engines from rotary, to standard inline 3-cylinder, up to 12-cylinder engines. Our application coverage includes model years 1960 to the current year with over tens of thousands of applications for domestic and import vehicles using ignition coils and coil on plug.
The Coil Boot, or Ignition Boot or Spark Plug Boot, connects the Ignition coil to the spark plug. We offer Ignition Coil Boots both individually and as complete sets so you can get the job done right the first time.
Symptoms of a bad Ignition Coil may include:
- Engine misfires or rough idle
- No start conditions
- Check Engine light on
