Spark Plugs

Me being lazy, was curious if anyone had come across any cunning (lazy) way of getting to the plugs without having to remove the side panels and air box. Can things be loosened and slid around? My side panels are tight to the engine bars, and all of a sudden it gets to be a bigger and bigger job.
There’s someone who sounds like Elvis on YouTube who seems to have cracked it, but his video is rubbish.

There very little room to slide the necessary bits out. Key pieces (airbox) have attached.sensors with short wiring harnesses. You'll need enough room to remove the ignition coils and room to insert the spark plug tool.

I suspect you'll spend twice the time on any workaround than doing it the right way.

(Tip - you'll detach maybe 6+/- wiring connectors. I used multiple colours of nail polish to be establish what goes where upon re-assembly.)

If the pugs are staying in for 60k I'd still recommend pulling them every service to make sure there's no corrosion in there. They sit real deep and if there's problems it's a nightmare to resolve.

If running normal copper plugs, I would stick to a service life of about 20k miles. I've gone longer but the gaps eroded pretty significantly, nearly double what they started at. The vehicle these were in had no issue with firing them, but it does put excessive wear and tear on the coils/coilpacks running huge gaps like that. Going for a longer service life should be saved for iridium/platinum plugs, they are durable enough for significant mileage. I swapped the plugs in my car a year or two back at 120k miles (original plugs) and the looked and measured like they were new.
