i decided this weekend that i wanted to install an oil cooler on the teryx. i bought an empi cooler with fan that i used to run on my baja's, a sandwich adapter from weller racing, about 12 foot of oil line, and the needed fittings. i have right at $300.00 for the complete kit. i hooked the fan up to a switch. when i filled up with oil, it took 3 quarts of amsoil synthetic! i run my oil level right at the middle of the low/high on the dipstick. thats a full quart of added capacity! stoked about that! the whole assembly fits right under my cooler rack with about an inch to spare in height. here are a few pics....
