Hi..
I'd spray anything on the intake runners that is ant-corrosion and won't
eat at the rubber pieces at the plenum end.

I have used a lot of 'Corrosion Block'  a nice aluminum /boat/aircraft
treatment juice in a spray can too.

I have never had *anything* ignite from engine heat that  was sprayed
and left on the engine.
'possible' I suppose ..
but highly unlikely.
Use common sense of course ..like don't cover an engine in engine oil
then go driving.
but no ..never any issue at all in that regard.
