brian -r Posted September 8, 2020 Report Share Posted September 8, 2020 Just a heads up for anyone thinking of trying BUR6ET plugs part no NG-3172. The batch I recently bought came with just the threaded post and no bulb shaped top apparently this is the way they are supplied now, Fortunately I have some spare screw on tops so my leads will still fit Brian Quote Link to post Share on other sites

iain Posted September 8, 2020 Report Share Posted September 8, 2020 Have you checked with NGK? Seems very odd. Who was the source? Iain Quote Link to post Share on other sites
Crawfie Posted September 8, 2020 Report Share Posted September 8, 2020 I got mine from the Green Spark Plug Company. They arrived without the screw tops also. Quote Link to post Share on other sites
RogerH Posted September 8, 2020 Report Share Posted September 8, 2020 I've given up on NGK plugs on the 4A. They lasted between 500 & 1000 miles - useless. I'm now using Champion L87Y and they get to 5000+ miles. Roger Quote Link to post Share on other sites
brian -r Posted September 8, 2020 Author Report Share Posted September 8, 2020 These plugs came from a local branch of Wilco factors and not discounted , so I would have thought they should be genuine. Who can be sure these days, only time will tell. In the meantime an e- mail to NGK has been sent Brian Quote Link to post Share on other sites
Andy Moltu Posted September 8, 2020 Report Share Posted September 8, 2020 Mine too came without the screw tops. Presumably whatever the intended fit meant doesn’t use them. Quote Link to post Share on other sites
OldBob Posted September 8, 2020 Report Share Posted September 8, 2020 I just bought some in cardboard boxes and they have screw on caps included. Bubble pack ones usually don't from what I have seen. Bob Quote Link to post Share on other sites
Tim D. Posted September 9, 2020 Report Share Posted September 9, 2020 Just out of interest. How often do people change their spark plugs? Quote Link to post Share on other sites
John Morrison Posted September 9, 2020 Report Share Posted September 9, 2020 Likely every two or three years, used to be 10,000mls recommended. OR, if there is aproblem! John. Quote Link to post Share on other sites
Lebro Posted September 9, 2020 Report Share Posted September 9, 2020 (edited) I have had no problem with NGK plugs, done at least 7000 miles by now. Bob. Edited September 9, 2020 by Lebro Quote Link to post Share on other sites

qkingston Posted September 9, 2020 Report Share Posted September 9, 2020 Hi Roger, you not used the Champion L82C as recommended by Green Spark Plug, any reason for that? Regards David Quote Link to post Share on other sites
Charlie D Posted September 9, 2020 Report Share Posted September 9, 2020 My daily driver is a Fiat Grande Punto. Apart from oil and filter changes I do virtually no routine maintenance. It now has 175,000 on the clock. (I bought it with 5,000) I eventually changed the spark plugs after 145,000 miles (No… not a misprint…) simply because I thought that if there was a misfire it might kill the catalytic converter.The plugs that came out looked perfect, and I’m sure they could have gone on for a few more thousand miles. Really was a case of “If it ain’t broke…” Charlie. Quote Link to post Share on other sites

trchris Posted September 9, 2020 Report Share Posted September 9, 2020 I use NGK plugs (BP6HS) with out a problem in the 4a I usually obtain them from Euro car parts at least then they should be genuine and a good price when you use the discount code the part number if any ones interested is 408991390 Chris Quote Link to post Share on other sites

Hi David, I have used NGK plugs since 1998 when the car got back on the road and they appeared to last well. In 2018 when touring Ireland I found that a newish set of plugs would have trouble when applying power in second gear at low speed.. Fit new plugs and the problem disappears until 500 - 1000 miles later. In late 2018 I fitted Champion L87 and they keep going for a lot longer (4000 - 5000 miles) before the same problem. Back in late 2015 I overhauled the engine and fitted a Newman PH1 cam shaft that appears to work well. Somebody posted on here a couple of years back that they had heard that new plugs have a thinner/reduced glazing on the ceramic and thus they do not like our wet engines.

Z320 Posted September 9, 2020 Report Share Posted September 9, 2020 (edited) Never any problems with Bosch spark plugs, the car came with WR8??(short electrodes), without any reason I swapped to WR78, to one with the 4 electrodes (X or G). Total 30,000 miles + Only to buy from NOS, but there are enough of them out there. Ciao, Marco Edited September 11, 2020 by Z320 Quote Link to post Share on other sites
stuart Posted September 9, 2020 Report Share Posted September 9, 2020 I never have any problems with genuine NGK plugs, reading above about the ones supplied without the end caps and the reply from NGK seems to show the fake plug problem is still going on.
