I understand that if you have an aftermarket plenum, an upgrade to a bigger oil cooler is possible. I have a 987.1 Cayman S with an IPD Competition Plenum.

Would both the 996S and 997S oil cooler fit? The 997 cooler is about a half inch taller, but also costs $50 more. Any opinions or experience with either of these? Any thoughts on this mod compared to the 3rd radiator? Tia

996S P/N 996.107.025.57 (Behr 376726111)

997S P/N 997.107.025.00 (Behr 376729621)

This is interesting. I am also curious if anyone else has done this since extra cooling on the oil would be nice. I seen some posts on here with after market coolers but some people reported leaks and other issues. But this one being from a 996 I would trust it more.

Edit: just did a quick search and found an article with the exact conversion, http://www.planet-9.com/reviews/cay...ns/p373-behr-376726111-engine-oil-cooler.html I will probably end up upgrading in the summer.

I have a cup car oil cooler on my 4.0L. The adapter was provided by Vision. No issues fitting or leaks

In the article he upgraded his Cayman cooler to the 996 S cooler. I'd like to upgrade my Cayman S cooler to the 997 S cooler. I'll probably just go ahead and buy it and and will report back if it works.
FYI Oscaroparts.com is selling both parts pretty cheap at the moment, there's a 15% off coupon advertised on their homepage.
