Don't buy the cheap ones as they don't work, the ones for £42 on the website burger put up can be bought at Wirral spares brand new for £20+vat (similar if not better) we have a set and they are excellent.
They need to be thick ones, your car will start instantly with those so no need to rev the car they are connected to and no waiting times.
Thanks a great help much appreciated
To be honest I can't see why you would need the 5 meter ones. I'd go for the 3.5 from euro parts and tap in parts 25 which will bring them down to £15ish then free delivery. Sorted
sorted now thanks everyone
