Been a while, but Calor Ayr now at 65p

The Mis-fire returned a couple of weeks ago........traced it down to a couple of coil packs gone south....... While trying to diagnose the problem, I fitted a set of BOSCH Super 4's...........what a crap plug.......... Mis-fired like a three legged horse in reverse. Going back to NGK BKR6EIX...........

Phoned NGK and they tell me that basically they are very similar but the LPG plugs have a stronger core to give a better spark to ignite LPG. They also have a more heavy duty insulation around the cetral electrode. He as...

Hi all.... Currently have BKR6EIX fitted to my 2001 BMW 525i (M54). Fitted for about 35k miles. Over the last week or so I have had a very noticable mis-fire while running on gas.
