i need to replace the oilcooler on my 99 e300 which comes to the cost of about 400 dollars. so was thinking of just adding a jegs universal cooler or something from pick n pull from another car... my question is what size/rating does everyone think i need to be equiviliant/or better to the stock cooler?

was thinking this might work http://www.jegs.com/i/JEGS-Performance-Products/555/51700/10002/-1?parentProductId=1032938
