Over on another car list I noticed a product, new to me, that some people were using to protect their Italian Irreplaceables that might work very well under the hood of our V12’s - and really - maybe any of our irreplaceables — which made it hard to choose a forum in which to post this.
$200 to $400ish?
FireSlayer appears to be a similar competitive product.
It looks like a PEX tube pre-charged with extinguisher agent and installed to the hood around fire prone areas. If a fire starts, and gets the tube in any spot to 240F or 120C, the tube explosively releases the agent blowing out the fire and chokes it with the chemical released inside. Routing would be important given the temps under hood.
No affiliation. Thought I’d pass along the info.
