20k Service & NGK Spark Plugs

anybody use NGK spark plugs in their RG? Oreily sold me some NGK, DCPR7E for my 10RGC 96". I have 20k miles and stock plugs are Champion and still look good, runs good.

Going on a 1400 mi road trip in 2 weeks and wondering if I should change plugs out and if NGK acceptable.

since my post found this cross reference chart.

I always replace my OEM plugs with the same every year. NGKs should be fine if they are in the appropriate heat range. The only negative comments I ever hear about plugs is about some of the fancier, more costly plugs like the E3 spark plugs. Some folks rave about the standard Autolite plugs.

i used to use the autolite 4164s in my bike. can't say that i ever had any problem with them, but when i bought my 2010, and was researching tuners, jamie at fuelmoto recommended staying with the stock plugs (and not the se) because of the spark knock sensor in our bikes. the ecm looks for a certain resistance value, and aftermarket plugs, may or may not, meet this value. so based on his recommendation, went with the powervision, and stock plugs.

I understand the concept of reality, but find it too confining for a way of life.

I run the NGK's in mine, no issues. I try not to run Champions(who makes the HD OEM plugs) in anything, had nothing but bad luck with Champions for years.

OEM and Autolites seem to work great for many. Other plugs may give you pinging and knock issues due to the ion sensing. Some will even cause a check engine light to come on.

2011 RGU with more money then sence in it.
Oh and its black because blacks faster.

I've seen more than 1 good engine builder/tuner recommend the NGK as not messing with the ion sensing. I normall run the DCPR8 plug, which is one heat range cooler. Cooler plug means less chance of the plug itself causing a pre-ignition issue.

I bought and installed the NGK Iridium plugs last spring. I've had people say I shouldn't have, but I have had no issues at all. Any reasons I shouldn't have?

Our old saying is the NGK stands for No Good Kind. That being said I have run them plenty of times without issue. Old mechanic joke.
