I changed the spark plugs on my Vee with 50,000 km soon after I purchased it. When I balanced the TB's, I found that spark plugs where not that accessible, so I decided to change them for iridiums (CR8EIX)
While I know that they are gonna last forever, I would have changed them back for new CR8EK with dual electrode if I didn't got a PC3. The dual electrode helps when the engine is in very lean condition.
My recommendation would be to stick with CR8EK or another multiple electrodes if not retuning the FI.
