This is actually an X-post from the 145/146 forum, but I'd like to read your opinion too.
As we all are aware, Golden Lodge spark plugs are hard, almost impossible to get hold of these days. That got me thinking: what to replace them with?
It's been almost 125.000 km since the car rolled off the production line, and after a few misfires here and there, I think it's time to change the plugs.
What brand should I look into? NGK, Bosch, Champion? I've asked everywhere, and all I got was a spark plug that looked nowhere near the GL 2HL.
This is a picture of 2HL plug, I'm guessing it's a quad tip or something:
and everywhere I've asked, they offered me spark plugs with that thingy on the tip:
something like this.
And that confuses me a little. 2HLs are designed to sit as close as possible to the piston head so the mixture is ignited without a misfire. Won't that thingy hit the piston? I've used Golden Lodge 2HL on my previous boxers, never ever tried anything else.
Need help, and it will be appreciated.
