2008/R56/N14 Cooper S Spark Plug Recommendations

Hello,

Picked up my 2008 Cooper S last weekend and looking to get my hands dirty this coming weekend.

I noticed that the air filter and spark plugs hadn't been changed in a few years by the main dealer, so I am going to do them anyway for preventative maintenance.

Should I be opting for one spark plug over the other? Was looking at NGK Iridium ones?

I picked up a 14mm thin walled 12 point spark plug socket and aware of being very careful not to cross thread. The Haynes workshop manual is a little vague, so any other tips?

Thanks,

Marcus

Hi,

Just a follow-up question regarding the spark plugs - is gapping still necessary?

Do new plugs come with the correct gap or is it better to always double check this?

Thanks,

Marcus
