Why do BMW change the plugs on a 2010 twin cam at 12,000 miles, but on earlier engines 24,000?
Is it to keep service prices high and to make even more cash for the dealers?
Please tell me why!
I had a 12,000 done in March and kept my old plugs, they look like new, so I'm not changing again till 36,000
Had an 18,000 done last w/end and asked the dealer why they change them at 12 and not 24? "It's in the service schedule"....but there's no need!!!!!!
Well at £44 and about £36 for labour it's a rip off and totally unnecessary in my opinion, if the plugs had worn electrodes change 'em, but NO, they were spotless.
No doubt someone will tell me why, but as far as I'm concerned it's bollox!
