After seeing how big and heavy the standard heater system / box was I opted for this kit car all in 1, it kicks out about 4.5 kw which is more than the standard car and is only 1.6 kilos and about 1/4 of the size which frees up a lot of space above the front of the tunnel. This will still take the cold air feed from the standard car inlet. I will have just the front panel poking out so will be neat and I can angle it to demise the front screen or I can add a pipe to the bulkhead of it.
