Oil Cooler HELP!

[Gatorman199]

I am looking to purchase an oil cooler for my 2001 300ex. The engine is stock, i got a pipe, ket kit, and air filter only engine diff's. What is a good brand to buy for a 300ex, around how much and does the oil cooler just snap on in a quick few min?, and is this a good idea to go on a basically stock bike?

All air cooled four strokes need oil coolers. I have them and yes they are easy to install. Can't tell you the price on here.
