.....cheers for the plug.................had mine fitted for over a week now.......£57 it cost.............purposefully let it run low on fuel and drove down back roads with the fuel light on and then the final test was going round the round about at jct 60 off the A1..................had the back end of the car out and it still didn't cut out,stutter or anything else..............so it's upto u really...........i asked about and had a mixed response (and also a lot of arse lickin' bandwagon jumpers on here......) but then i asked my tuner and he said he's had no problems with the copied ones...........
