spark plugs for 1150RT


Recommended Posts

You're probably going to get some different opinions here. I run Autolite 3923's as do a lot of folks (from what I hear). They're 2 bucks.


However, I've tried probably 6 or so different types (including the OEMs) as I was experimenting with surging issues. Unlike many reports across the internet, I noticed/felt almost no performance/surging differences based on the plug. YMMV.


I believe BMW specs NGK BKR7EKC.
