Hi all, the brain is starting to get into gear for an upcoming big trip and my thoughts are turning to servicing. While I'm pretty sure I'm on top of filters and oil, plugs are causing me a bit of a problem. I'm looking at fitting iridium plugs, most likely NGK, but have to decide between cr8ehix-9 or cr9ehix-9. Has anyone had first hand experience with either? i'm leaning towards the 8's for their allrounder ability but am open for change. Thanks.
Update, just found another thread where they recommend cr7ehix-9. the use of my bike indicates to me that the 8's would be a better choice but again, am open to change.
