Ok as I'm selling my car I no longer need this. I was goin to fit it to my m50 to keep the oil cool. So its basically m3 oil filter housing with the outlets for the pipe work and the oil cooler. Will need 4 New o rings these cost a few quid from eBay. Excellent upgrade for your m50 or m52 and its just a direct fit. Normally cost about 100 quid for just the oil filter housing. I'll sell the lot for 125 posted.
