The Sparco SP-305, a 3.9 litre electrically operated plumbed in fire system. Part number 014778EXL3.
The extra capacity is the reason to choose this over the 2.5 litre SP-205. More extinguishant means longer discharge, and in a bigger cabin or a car with a large engine bay that matters. Some regulations also specify a minimum capacity by vehicle type, so check the wording rather than assuming the smaller bottle will do.
Approved to FIA Technical List 16, with environmentally friendly AFFF extinguishant, complete with mounting bracket and straps.
What to check first
Technical List 16 systems are accepted in a great many series and not in all of them. A number of championships now require FIA 8865-2015, which sits on Technical List 52 instead. Read your own regulations before you order.
Where it has to go
The bottle is 346mm long and 130mm in diameter, which is a substantial thing to find room for and noticeably bigger than the 302mm by 110mm of the 2.5 litre. That difference is worth measuring for, because it is the usual reason someone ends up back with the smaller bottle.
It has to be mounted where a belted in driver can reach the actuator, with an external pull a marshal can reach. Both are scrutineered, and so is bottle orientation.
Alongside it
Most regulations that require a plumbed system also require a hand held bottle in the cabin. Tell us the car and the class and we will make sure the whole arrangement satisfies your scrutineer rather than most of it.
What is the difference between mechanical and electrical systems?
How you set them off. A mechanical system fires by pull cable from the cockpit, an electrical system fires from a button that can sit anywhere and adds an external trigger point for marshals more easily. This is the electrical version. Both plumb into nozzles around the engine bay and cockpit.
Is it accepted by scrutineers?
It carries FIA Technical List 16 Approved status. Extinguisher requirements are set per discipline, including capacity and whether a plumbed system is required, so check your regulations for the exact requirement and ask us if you want us to match a system to your series.
Does it need servicing?
Yes. Extinguishers carry a service date and need periodic servicing to the manufacturer schedule, which scrutineers do check, so factor a service into your running costs and note the date on the bottle when it arrives.
Can I install it myself?
A competent home builder can: the work is mounting the bottle securely, routing the plumbing to the nozzle points, and rigging the trigger. The instructions cover the layout, and we can advise on nozzle placement for your car if you tell us what you are building.
