Now… I’m looking all over for the info I got on the extinguisher. I can’t recall how I asked, but I got the answer here somewhere telling me the factory one will pass tech, despite the slight size issue. I’ll keep digging to try to find the email, or maybe someone of authority can put the answer up in here.
As for the ventilated seats… I’m not 100% sure what you’re asking me.
If you’re asking whether the factory mount will attach to them, then the answer is yes. I’ve got the 18-way ventilated seats and it came with the extinguisher on the passenger side. Whether or not there’s a specific mount for this, I have no idea.
If you’re asking me whether the extinguisher is capable of putting out a fire that’s being fed massive amounts of oxygen by the hurricane-like power of the ventilation coming from the seats… well… I hope I never have to find out. 🙂
