If you mount your ignition coil inside of the passenger compartment, you may want to route the spark plug directly through the firewall. An ignition coil bulkhead passthrough can help to prevent voltage leaks from occurring with this configuration. Choose an MSD Firewall Feed-Thru that will provide protection, prevent sparks from getting grounded and keep the passenger compartment protected from engine heat and gases. Search or browse by brand or part category to find the best performance truck parts for your ignition set-up and engine. 4 Wheel Parts is your one-stop shop for Jeep performance parts and truck performance parts.

Why Use a Passthrough?
Routing an ignition coil directly through the firewall reduces the likelihood that a spark will get grounded prior to reaching your engine. Spark plug wires routed in less efficient ways may run a higher risk of grounding or compromised seals that allow heat and noxious gases to enter the passenger compartment. An ignition coil bulkhead passthrough helps to ensure that the spark of the coil reaches the distributor.

Quality Performance Parts
In addition to determining the best wiring solution, you should also factor in the quality of the truck performance components you use. MSD makes high-quality ignition components. Their Firewall Feed-Thru is molded from Rynite and nylon with half an inch of insulation. These performance parts are durable enough to stand up to conditions under the hood of a rig equipped with performance parts.
