To be honest I wouldn't trust a stealer to replace the "standard" ones, they told me they did mine twice and it was in 9 times, they said they had done the gearbox one but the battery hadn't been removed !!! not sure what magic potion they used to changed that then !!! it started at 7k and when I had done 60k and it ran out of warranty it was still there and they said they had changed em and now me warranty was up there wa snowt they could do !!!, not convinced they changed anything other than their flavour of doughnut for that day !!!.
Bought the K-Tec one and it went and never came back !!! how odd !!!
Most stealers = thiefs IMO..... find a good indy who you can trust....
