I've the 5kg version from JJC in the MG and it was easy to fit. I put one nozzle under the steering column and one in the nearside of the engine bay pointing towards the fuel pressure regulator and the Holley carb.

The only fire I've ever had in 40 years of driving / over 100 vehicles is a dash fire caused by a previous owners bodged wiring. Just glad I'd got a hand held extinguisher to put it out as if a plumbed under bonnet would have been of no use. If you have open throat twin Webbers or similar that backfire, competition car, want it for looks etc then go with plumbed in but otherwise a decent hand held (or two ? ) inside the car would be more useful and far cheaper.

I've recently got one of these which I'm installing in a trackday car. It's the Lifeline version which cost about the same (probably the same under the stickers!)
Nice little kit comes with stickers, pipework, the nozzles (which I believe are the expensive part when you look them up) and 2 pull cables (which aren't exactly cheap either)
The instructions do say 1 for the car and 1 for the bay, I was in 2 minds whether to put them both in the engine bay as I have a hand held one too.

There is some logic to what composimmonite is saying. Handheld is totally portable so you just grab it from wherever you've mounted it, go direct to the fire and put it out. Having something going off automatically under the bonnet is a bit destructive and might not be aimed very well or may not even work. They're not very easy to test are they. And having one go off and unnecessarily ruining your car by covering it in extinguisher foam wouldn't be a happy accident either.
I'd say leave plumed-in for the professional race car builders who've done it hundreds of times before. Try not to get caught up in over complicated gadgetry. It's easy to miss the point sometimes, when you see something shiny in a catalogue.

Why do you want an extinguisher? Is it to save your pride and joy if you have a fire, or save your life if you're stuck in a burning car?
A 2.25l AFFF is a waste of time for the former, irrespective of handheld or plumbed in. While AFFF may be very 'green' it really is hopeless at knocking down a fire. The professional fire crews at work were amazed that the MSA consider AFFF as a suitable agent.
Just to give you an indication of just how much extinguishant you need, a couple of years ago, I was first on the scene of a minor under-bonnet on a Rover 25 (a car I know very well as it is my current rally car). I was there literally 10 seconds after the owner first noticed smoke. I had a 2.5l AFFF and a big dry powder extinguisher (4 or 6kg) in the car, so had a go at tackling the blaze. Completely discharged the AFFF - no effect. Used the dry powder - also no effect. Ran up to the local petrol station and grabbed a couple of their really big foam extinguishers and used those. Still the car burnt. And that was on a car I knew exactly where to point them. In the end the FB came and sorted with a couple of hoses from the fire engine!!
Point being small extinguishers should be seen as being just there to buy you a vital few seconds to get clear of the car. FWIW, I'm just reshelling the rally car and I'm not bothering refitting my AFFF plumbed in system (I bought it before I knew how rubbish they are); I'm currently saving for one of the 'halon replacement' style.
