Is eBay not an option? Not sure if the H ones will fit as I have no idea what it stands for....

I think the H in CR8EHIX-9 stands for Honda.

So the plug may only fit Hondas as they may have a different pitch of thread.

You got it half-right. The H has nothing to do with Honda. The H is the code for 12.7mm thread reach. See useful plug link below:

Short answer No. They will not fit as there is an unthreaded shoulder on the CR8EHIX9 between the sealing washer and the threads, the CR8EIX do not have the shoulder. See Pictures below
