Default 740 air intake

Just got a 740 turbo. It's an 87 so to my understanding the thermostat is in the airbox. The flap in the airbox is broken and i have seen air intake kits for sale on a site. So what would i do with the thermostat?
Thanks

you don't want to add heated air to your intake charge, ditch it, don't look back.

The Thermastat was installed for cars in cold weather climates (not sure on the temp it opens) im also 50% sure that its a emissions required thing, cause even turbo cars got them and it seems kind of a waste of plastic and metal.

Remove the metal hose and the thermastat, then either glue or screw the flap shut so only "cold" air enters the Air box,

I have been driving for about 15 years on several Volvos with/out the preheat. Worked fine at -20F in Chicago.

On my current ride it went bad and I had massive ping on anything more than idle - before I could pull it out. Limped home and it seems OK now with it removed. Wonder how many miles I took off AMM, turbo, and other components.

sweet. Thanks everyone. I'll remove the thermostat as soon as i get it home. The flap wa actually glued open but the glue came off. Has anybody had any good experience w/ an aftermarket intake? I was looking at getting this Ultra-Flo Intake.

There are writeups floating around. But the way I've got mine setup is I capped off the hot air pickup side with a paint can lid. Then cut the thermo flapper out of the bottom with a keyhole saw lined up to put a 3" radiator pipe through the knockout directly under and in front of the box.. It passes cali emissions testing w/ flying colors.

You can remove the box altogether and put a cone filter on just before the AMM, then just rig a support for it.
