Just under £500 delivered from P.T.S, you have to ask them about them though, because they dont list them in their catalog or advertisments.
They said they have been using them in their rebuilds on rsts recently and supossed to better than accarlite, but they would say that when something costs 500 quid!,
That why i put this post up, to see if any one is using them, nice to use something different other than mahle.....
