Left them in. Will consider replacement at 50k klms.
I would like to apologize to anyone I have NOT offended. Please be patient. I will get to you shortly.

Why would you not replace them when the manufacturer states to do so at 12K miles? They're cheap. Takes less than 30 minutes to replace.

You could take them out and have a look then decide whether they need replacing.
Carpe Diem!

Did someone say that BMW spark plugs were cheap.
Current motorcycle collection: 2002 Yamaha FZ1; 2005 Triumph Bonneville T-100; 2011 Royal Enfield Bullet 500; 2009 BMW F650GS; 2016 BMW R1200RS; 2011 Zero S 16.6 kWh

If you want cheap, the spark plug used in my Royal Enfield is $2.50. I bet your BMW plug costs more than that.

Zitat von MrVvrroomm im Beitrag #3 I'd really love to hear BMW's take on why they feel that's necessary. Iridium plugs are reckoned to last at least 10x longer than normal ones. I've read on other forums that users are even considering them to last the lifetime of the vehicle. I'm not advocating that, but 12K miles? Crazy.

Zitat von MrVvrroomm im Beitrag #3 At 12k miles I replaced my left one only because the right side was replaced when the cylinder was repaired following my accident. On inspection it did not need to be replaced but just to "keep them even" I replaced it. I did not need to replace them at 24k miles either but I suspect that I did since I had got them at a good price and had not done anything to the bike for a while prior to that. Point is, the manufacturer says to change every 12k miles but I think that is overkill since the plugs are still good and would only need cleaning (that is, if the bike is running properly in the first place).

Zitat von Grumpy Goat im Beitrag #8Zitat von MrVvrroomm im Beitrag #3 Replacing the plugs at 12k in a water-cooled, fuel-injected engine with electronic ignition seems more than silly. Right up there with a 12k plug replacement on a diesel. Old Forum Orphan |

Zitat von Mr. 36654 im Beitrag #9 Especially when you see how clean the plugs are when removed. I guess BMW requires this change to ensure best possible emissions.

I have to feel that it is all about $$$ |

Zitat von MrVvrroomm im Beitrag #11 For the same type of plug? Could you post the link? I still have 8 sitting on the shelf from when I bought the bikes. The shop gave me a discount on maintenance items, so I stocked up.

Zitat von Lee im Beitrag #13Be careful though, apparently there are fakes iridiums around. Eg: http://www.ngk-sparkplugs.jp/english/techinfo/fake/index.html https://www.driven2automotive.com/blog/how-to-spot-fake-ngk-cr9eix-iridium-ix-spark-plugs-2018/
