Sounds like a cooling plate for your Rad! that traps cool air for your radiator so if it is , dont.
Post a picture up so we can see for definate
ive got a black platic sqare that sits next to my rad,
i think its like a blockoff plate thingy, as the ek9 chassis has two rad, where i only have one...is it thins ur on a bout mate?
ok i wont remove it but i don't get how that could make the engine bay get hotter. and by the way its not on the radiator its next to it. and its also colour coded with the car which i think it also makes it look nicer when you see it from the front bumper. i just never knew it could heat things up.
thanks for your commence tho
