See alot of the 5671 through 5674's used..........
How does the NGK UR5 compare to this and what is the difference as well?
Friend of mine has been using the UR5's in 588's with 14-71 blowers and they have been great other than one engine starts hard every now and then. Once running they are great, hence being curious if he would benifit from a different plug.
Thanks
Jon

It's just the one that starts hard now and then, but it only seems to do it when the engines are totally cold.
If they have been run, then they fire instantly.
