Single elektrode spark plugs for M50?

[Morgenster]

Hi guys,

I've been looking all over the web and I just can't find a partnr. for single electrode plugs for my M50 (at least not chez Bosch or NGK).
Does anyone have a reference?
The LPG specialists I went to explained to me that the single electrode plugs are way better for avoiding powerloss and backfires.
TIA

Bosch F8LDCR is recommended for my 2.5 M50

Yeah I know those are recommended, but I'm pretty sure those are two-pronged. I need single prong that can be gapped.

I've run across plenty of M50TU (US) engines running the Autolite 3923 plug (about $2 each, USD) and I can honestly say the cars ran great and got superior fuel economy before I changed them out to BMW OE NGK or Bosch plugs with multiple tips. I'm not saying I endorse or use them myself and I did change them just so my customers wouldn't think me a hack, but I was impressed driving cars that had been using the cheap Autolites for quite some time with no problem. YMMV

Can I obtain those autolites in Belgium?
Am I to conclude that there are no single electrode plugs for the M50 manufactured by Bosch or NGK?

Can't find Bosch number that easy... but with above info... you should be able to find one.

Very helpful indeed! Thank you very much!

They work great, its just that tuning my engine in the winter was a pain on them

[Morgenster]

Why was this a pain?
