Only 2 real choices for oil coolers. FI or Z1. Get a 34 row cooler. Forget about a 25 row if you track. The FI kit for the newer Z's has the block off for the factory cooler. Get the thermostatic plate too. The plate stays 90% closed until the oil reaches a predetermined temp then opens up to 100%. The reason the plate stays 10 % open when cold is so that you always have some oil flowing through it. It preheats the oil in the cooler so that cold oil coming into the engine when the plate fully opens does not cold shock engine parts.
Stay away from the Mishashitymoto cooler. It has been known the fail.
