The Sparco 4.25 litre plumbed in electrical fire system. Part number 014772EXL.
This is the largest of the Sparco plumbed systems we carry, and capacity is the reason to choose it. More extinguishant means a longer discharge, and in a big cabin or a car with a large engine bay that is what you want. Some regulations also specify a minimum capacity by vehicle type, so read the wording rather than assuming a smaller bottle will do.
Specification
A steel bottle filled with AFFF foam based extinguishant, electrically activated, approved to FIA Technical List 16 and to MSA standards, for closed cockpit saloon cars.
AFFF is effective on fuel fires, which is what you are actually protecting against in a competition car. It leaves a residue that needs cleaning up, which is a problem you would be glad to have.
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, because this is the most expensive thing to get wrong in a build.
Check the packaging as well. A 4.25 litre bottle is a substantial thing and it has to be mounted where a belted in driver can reach the actuator, with an external pull for a marshal. Both are scrutineered, and so is bottle orientation.
Most regulations that require a plumbed system also require a hand held bottle. Tell us the class and we will make sure you have both.
