As said most people don't feel the need until 280-300hp...But if the car goes on track oil gets silly hot.
Some people mount them on inner wing with an air feed since space is so hard to come by at the front. A 10 row cooler won't need another pump IIRC...
That ad though the only thing worth money is the fittings, the cooler looks battered. Get a nice Mocal with strong piping and you're sorted.
