I notice you have a newer LT, did you notice any performance difference?LAF said:Don't know about experience but I did the 12k and used the NGK and don't seem to have any issues.
I ran them in a high compression V-Twin and they were fine there also.
That iridium is tuff stuff.
I don't think plugs or fuel or air filters need changed at 12,000 based on what I saw on mine at 12000. I will do it while my warranty is intact, but after that I will run the plugs, and air filer 24,000. I will hold judgment on the fuel filter after I do my 24K. At 12k I could not get any dirt out it no mater how hard I tried.
I am not one who believes spark plugs give any performance gain. No matter what the hype. Even guys who Index Plugs say it is more for them, then performance.SmokinJoe said:I notice you have a newer LT, did you notice any performance difference?
BTW I did my air filter @ 12K (way to soon), fuel filter AND metal quick connects @32K. (just for preventive maintenance.) Now time to do the air @ 40K....

I question the single ground on the NGK as compared to the split ground on the Bosch.
