Frequently asked questions

Why use a firewall bulkhead?
It seals the firewall, stops hoses chafing on sheet metal, and lets you split the A/C and heater lines into engine bay and cabin sections so the unit can come out without cutting hoses.

Does it suit your electric A/C kits?
It suits most hot rod heat and cool setups. Message us with your kit and fittings and we will check before you order.

How do I fit it?
Mark the plate on the firewall, drill or hole saw the port holes, seal the plate and bolt it through.
