Andial or Garretson intercooler upgrade & engine bay seal insulation
 

I have a couple of questions:

1) If I upgrade my OEM intercooler to an Andial long neck,do I need to remove the OEM air filter box? Would the Andial fit with the air box in? I see lots of air intake modifications when these oil coolers are upgraded, but want to make sure before I buy this IC.

2) Engine compartment insulation- I removed the heating system and heat exchangers for headers. Work perfect. Still, now I have some holes in the engine bay that remain after these ducts were removed, leaving some areas for heat convection from headers/ exhaust performance muffler and K27 turbo to potentially ascend(hit air always goes up!) into the engine bay/ intercooler/ a/c interaction.

Car runs very nicely in FL summer heat(90's) weather at 190°, raises to 200-210° in traffic jams but I have a front oil cooler, so never higher than that. My car is black,and want to stay away from those orange/ red or related silicone materials. Prefer black or related.

I am thinking on "sealing" those gaps/ holes with foam, rubber or related (fire retardant of course), any suggestions and where to get these?

Thanks, Carl

Carl,
Got your PM asking the same as above.
The reproduction Andial/Garretson IC shrouds that install within the rear wing are $138 + S&H.
No, you do not have to modify or remove the air filter housing.
Close up the holes in your engine's sheet metal, and cap the old heater ducts on the engine and chassis. Doubtful you'll find large rubber seals that will fill the old heater duct holes or will last in the het. Foam?!? Thin sheet metal is easily cut with tin snips, paint black and secure to the engine's tins.

Thanks.

On the foam possibility, as it allows air / Water through but will prevent convection of heat into the engine bay, do you recommend any particular type, maybe a/c quality or like, as they should be fire retardant.

Still, I believe the thin metal option/ painted black is the best/ longer lasting one.

Search for my new posting (911/ 930 Engine bay seal) on the Technology 911 forum following your instructions. Thanks.

Will get back to you when ready for the intercooler. Thanks again, Carl:)
