When has everyone change the sparkplugs on your N55? I'm around 42000 now miles and wonder if I need to do swap them out soon.
I change mine every 30K or so with NGK 97506. 2 steps colder on the N55. Gap = 0.020" as I generally run pump fuel and meth PI. 0.018" if I run high concentrations of E85. FBO e90 N55, Pure S2, Meth PI.
SO, does an oil catch tank help reduce this?
Think I will install one on my N55 and see. Can't hurt, right?Actually it does help slow down the build up, especially on n54 engine. Some said not so much on n55. I installed one ~2 months ago, I haven't been putting lots of mileage on my car (roughly~2k miles), I'll check this weekend to see if anything. lol
