I can't tell you the RPO code right now, but there are water lines that come from your radiator and go the the top of the oil filter, then back to the radiator.

The RPO is KC4. It is only gound on 87 to 90 IROC's and 91 to 92 Z-28's. It consists of two coolant lines that run to and from your oil filter base.

the oil coolers are a rare option, generally packaged with the G92 package (on the Camaros at least)... they aren't really that good of a setup, but if you can get a stock oil cooler and run the lines into an aftermarket cooler.....
