Changing plugs at 10k is a total waste of time and money.
My 2021 V7 E5 (850) has iridium-tipped plugs and yet the maintenance schedule requires changing them every 10,000 km (~6200 mi). This doesn't make sense to me. If you're going to change them that often, then why use iridium tips? Any insight will be appreciated.
I can understand the 5000mile change spark plugs of yesteryears. Plain sparkplugs, leaded fuel, poor airfiltration ( yes that means you K & N), weakish coil output etc.Todays iriium plugs are brilliant and rarely wear or fail.Using these also greatly reduces wear on the threads that hold the plug in, just remember the anti seize. A mk 3 lemans in heavy rush hour traffic in 34 deg heat spitting a live spark plug agaist your leg IS a learning experience and an unwanted distraction.I recently removed the iridiums from my sons car at 80, 000 km as the manual called for change, all were a good colour all had the standard gap, no they didnt have antiseize OEM fit from new. They could have gone back in with no issues.So if you run them maybe pull them every 40,000 km and have a look, change if gap is expanding or theres damage.

On my V7 Stone, the plugs look pretty grotty after 10 to 12K miles. Gap noticeably widened, ground wire rounded, all kinds of brown crap on insulator. I’m not going to file the ground square, or try to re-gap it. I change them. They are cheap. And sure enough, it runs better with fresh plugs. In my opinion, you can save money not changing the oil filter so often. Once every second or third oil change (12 to 18K miles) is fine. Same for air filter. Unless you live 20 miles down a dirt road, I’d run the air filter for 30 to 40K miles. In contrast, I like good spark.
