NGK CR8EIX or CR9EIX
« on: 17 March, 2019, 01:49:05 PM »
Afternoon all,

I have a 2009my 1050 and am in the process of giving it a full service in preparation for the fun season!

I wish to order NGK Iridium plugs but cannot find any solid confirmation of which are the correct plugs and both 8-EIX and 9-EIX come up in online searches.

Can anyone confirm either way, and why one is right but not the other?

I am in the UK if it makes a difference.

TIA

Std plug is CR8EK, so it follows that CR8EIX Is the iridium, oh and that's what NGK list.

 My owners manual said CR9EK.....however, I removed CR8's.....I'm 99% sure they were factory. It has only 9000 miles and everything else looked to be untouched. I'd go CR8.  (2010 model)

My 2008 came with CR9EK plugs from the factory. My 2008 owners handbook and service manual (issue 1, 11/2006) both spec CR9EK as well. Triumph changed to the CR8EK plugs sometime in 2009 I think. The service kits I used for the 12K and 24K services came with CR8Ek's. Not sure why they switched, maybe it had something to do with the piston issues some early bikes suffered. Sometime in 2010 Triumph also issued revised tunes to deal with the E10 fuel sold in the US and other countries.

It all depends upon the jetting/exhaust/ air filter/use of your bike as to which # is best. 8's are a little hot and 9's a little cool for mine. So I use the 9's. I've gotten 40k miles out of each set of those (6 sets on 2 bikes) before showing much wear. Paid about $6 a plug if I remember right.

Thanks for the replies gents.

So the consensus is: CR8EIX.
