Mulfab radiators every time, why buy a copy of something that's perfect? I have had Peters radiators in my cars since 2002, never had a failure. My 2008 +4 sheared its top outlet on the factory radiator, I have since heard from many other owners that theirs did the same, and the Mulfab radiator is a superb piece of engineering. These items are not cheap so I did not want to risk going to something unknown when there is such a track record of quality products, it helps that they are 20 miles from me as well ;-).
