Sospan, My plus 4 has the ITG cold air intake kit as supplied by williams. It takes air from above the radiator through the grill but... the filter canister is mounted directly above the exhaust manifold, almost touching it in fact,...... and yes it gets blooooody hot. Were I to want to install a hot water system for making tea on the go it's where I'd have chosen to fit it. I'll have to see about raising the mount and shielding it but for the love of God who the hell thought that was a great installation option........ might be good in northern Canada winter though gloomy
