that all well and good if after a accident you are able to get to the car ,and if they do discover it they will just say null and void and then you are in the deep poo ,I used to have something like rover rons fitted , and to be honest yes it did give a bit more power but it was just using more of the black stuff ,oops sorry that's because I am in Ireland still ,but you know what I mean and I got through turbo tubes quickly so have not bothered since and I do not think I will ,but if I do I would tell my insurance ,as they are getting so hot on.:angel:
