Does anyone know the size specs length x width x height of the 997 radiator? I think it is part number......

99610603775

Is there a similar size but better efficient unit available (but with the same attachment brackets and hose locations?

I have a GTB1 Cayman with a 997.1 front bumper and want to upgrade my cooling, with hot air out the smile slot.

I think I have all of the necessary hoses and forward GT3 rad bracket, but I guess I am looking for the best radiator I can find

Thanks for your help!

 

CSF makes one

So does PWR (good stuff, very high quality):

If you have all the hoses including the smaller breather hose, CSF 7053 would work, if you just have the main inlet/outlet hoses you could use CSF 3553. CSF 7053 is the high performance version.
