NGK Iridium, it’s what I get about everytime.
Recently got the following parts: Racingline VWR Springs 034 Motorsports strut mounts, new bearings and bump stops Rear strut mounts with new hardware and bump stops Deautoled LED license plate OEM Autodimming rear mirror with wiring harness APR boost tap NSP boost gauge with vent Hella oil level sensor Oil pan w level sensor European Headlight Switch APR Coilpacks Spark Plugs NGK BKR8EIX R LINE CENTER CAPS
Just changed mine out for the second time 2012 w/ 172k. Misfire engine code. NGK iridium. Getting 10 more mpg. Best 50$ I’ve spent in a long time
Iridium will last longest. Grab them if you race or run the piss out of that bike but for all intents and purposes a plain old NGK is plenty adequate for everyday riding and then some.
Ngk have been pretty reliable motor craft is pretty good too but I've seen good life spans for both.
Very broadly, only use NGK, Denso, Bosch, or Champion.
according to my halfords e- receipt i last used cr8 iridium plugs, no complaints here.
NGK all day, compared to all others they’re just made better, I bought Bosch platinum for a VW and the OE came out were NGK, after 50k they were still visually a better manufactured plug. Example- the plating on the Bosch threads was rougher.
That’s curious….. if you look closely at the end of the shorter plug you can see another set of threads, it looks like there an insert threaded onto that spark plug. It would appear that it wouldn’t be sitting where it needs to in the combustion chamber so that may explain your misfire.
I also just put in a set of NGK BKR7E's and gapped them a little large (.034) seeing as the ones I pulled out were at .043 That did nothing and the issue is still persistent.
