richaras Posted September 28, 2023 Report Share Posted September 28, 2023 Recently fitted a new set of NGK BP6HS. One failed almost immediately with a broken ceramic shroud around centre electrode. Previous set lasted 15000miles and made in Japan. This latest set made in Thailand. Rimmer have replaced one only. Anyone else experiencing problems with NGK? They used to be high quality and some thought better than Champion. Thinking of returning to Champion. Quote Link to post Share on other sites

richaras Posted September 28, 2023 Author Report Share Posted September 28, 2023 Surely not if bought from Rimmer at the TR international? Quote Link to post Share on other sites
stuart Posted September 28, 2023 Report Share Posted September 28, 2023 Well I have on my bench a brand new box of NGK plugs and they’re made in Japan. Supplied by my local motor factors, genuine NGK are made in Japan Stuart Quote Link to post Share on other sites
keith1948 Posted September 28, 2023 Report Share Posted September 28, 2023 If you Google 'how to spot fake NGK plugs' you will find a lot of useful information. NGK traditionally made in Japan but I have read they do have a factory in Thailand. The one you had that was broken may be genuine and just have been damaged when you bought or fitted it. On the other hand it may have been a fake. There is a lot of info on how to tell a fake plug. The boxes are not the same and the writing and stamping on the plugs are different. Just because it came from Rimmers doesn't mean they are immune from fakes. The fakes are widespread unfortunately. I bought some NGK plugs for a MK4 Fiesta not long ago from Halfords and their supplies came from somewhere in Europe. I checked the boxes and plugs and they appeared to be the genuine article. Modern times I'm afraid Keith Quote Link to post Share on other sites

Stuart. I have recently purchased (for my boat engine) some spark plugs from Spark Plugs.co.uk Very helpful people, & definitely do not obtain their stock from anyone other than the original makers or their distributors. Would highly recommend. Bob Quote Link to post Share on other sites
AndyR100 Posted September 28, 2023 Report Share Posted September 28, 2023 I have used the Green Spark Plug Company for some time for NGK’s and never had an issue with their plugs. …… Andy Quote Link to post Share on other sites
Icarus60 Posted October 2, 2023 Report Share Posted October 2, 2023 I have previously purchased NGK plugs, from reliable sources, that were not made in Japan so I asked the manufacture the question, and they have replied as follows: ”Niterra (formally known as NGK Spark Plugs) have for decades had manufacturing sites based all over the globe. The same quality standards that the company has built its reputation on apply across all plants, irrespective of manufacturing site, be it Japan, Thailand, France, India, Brazil, etc... We can assure you that BP6HS has indeed been manufactured at our plant in Thailand.” They also advised me that they have an article (available in the first few pages of their classic downloadable catalogue -https://www.ngkpartfinder.co.uk/assets/Uploads/Classic_May2022-ver3.pdf) that may be useful to classic car owners.

richaras Posted February 13 Author Report Share Posted February 13 Rimmer supplied replacement FOC (for one with broken shroud) but still misfiring with new set NGK (MIT). Rimmer and NGK swear that plugs are genuine NGK. Put old set (done at least 10k miles) NGK (MIJ) back in, guess what, no misfiring. Rimmer have replaced all 4 plugs now but with NGK (MIT). I think I'll try just replacing one old MIJ with one new MIT and test to see if I can identify which of the new MIT is faulty. Can they be all bad? Quote Link to post Share on other sites
