Iridium plugs
« on: December 26, 2023, 05:04:52 PM »
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.

Hi Bucket, I'm running NGK CR7EIX Iridium IX Spark Plugs in my ST1300 and have never had an issue with them whatsoever in the 3 1/2 years since I installed them.
From my experience it's cheaper to buy them from the UK (even with shipping costs) than buying them in Oz.

I got mine from here: https://www.driven2automotive.com/shop/ngk-cr7eix-7385-spark-plug/
Cheers  :beer

Wherever you end up purchasing them from, just be aware there are a lot of fakes out there...  :cuss

Thanks for the replies, looks like the '7's' might be the go by the sounds of it. I had a set of '8's' lined up through Amazon from the USA at a good price, $65.11 AU delivered. I'll have a hunt around for the others now. Just for reference, I also found these on Amazon.  https://www.amazon.com.au/NGK-Iridium-Spark-Plugs-CR7EIX/dp/B0042LRMHW/ref=sr_1_2?crid=1K63EYC9BWNNJ&keywords=NGK+CR7EIX+Spark+Plug&qid=1703826630&sprefix=ngk+cr7eix+spark+plug%2Caps%2C278&sr=8-2

Cheers Bucket...  :beer

Just be aware that Amazon was one of the companies reportedly selling fakes, as was eBay...

Thanks for the heads up about Amazon. I was looking closer for some sort of guarantee about being genuine, but couldn't see one. I haven't ordered yet but will make further enquires.
