Guys
Can someone confirm if there should be thick insulation matting on the underside of the engine compartment /bonnet mine is a 2.5 1988 Lux there is no signs of it ever being applied .
Thanks
Brian

Mine doesn't have any, nor does it appear ever to have had it (a '92 S2).

I recall contemporary reports that 924s in dark colours in the US and other hot climates suffered fuel injection problems...maybe early 944s were fitted with underbonnet insulation?

TBH I'd be glad of something to deal with the condensation that drips off the u/s of the bonnet and on to the servo and strut mounts....

Hi Brian,
I believe, like Graham, that the insulation was dropped on the later cars. My 924 had it, but the 944 (1992 S2) doesn't and never has had. Actually, on the 924 it was a pain because it dries out with age and gradually changes into a powdery deposit which gets all over the engine bay. There are lots of threads on Rennlist about the best way to remove it, which is not easy and always messy. I'd say you're best off without it!

Cheers,

My 85.5 had it.

As said above, I had it on one of my 924S models and it became brittle with age and flaked off all over the engine, horrible messy stuff to remove. Your better off without it![]

A 1988 car probably never had it. It was around then that Porsche stopped fitting it.

My '91 S2 has only a small square (about 5" a side) of insulation approximately above the AFM. Otherwise no insulation or glue residue, etc. to indicate insulation had ever been installed.

Just for info my 87 'S' had it but my 89 Turbo doesnt, and looks like it never did.

Hi Brian,

Which probably means you could pay 50% less at Porsche []

One of my clients manufactures these for many vehicles. I will check with him if they have done any 944's or 924's previously
