This chart lists replacement spark plugs that are MINI factory original replacements or the NGK equivalent of the same plugs. Modified MINI's may require different plugs.
Spark plug technology has come a long ways and the modern plugs last a lot longer than in the past. However, they DO wear down and can impact your engine's efficiency. The factory might recommend a 100,000 mile interval for replacements but most MINI owners replace them much sooner. Since a worn spark plug can affect your fuel efficiency, we recommend you inspect them regularly and replace when they start to show signs of wear.

ALWAYS torque the spark plugs to the proper torque setting:

• 27 Nm or 20 ft-lb for Gen 1 MINIs (R50 R52 R53)
• 23 +3 Nm or 17+2 ft-lb for Gen 2 MINIs(R55 R56 R57 R58 R59 R60 R61)

All current MINI models have spark plugs located at the bottom of a deep well - this requires special 'extended' spark plug sockets. On the Gen 2 2007+ models, the spark plugs are Bi-Hex so the standard hex socket will not work. Take a look at the Spark Plug Socket part numbers to see what you will need. We also recommend the use of 'locking extensions' so the socket does not get stuck on the plugs.

Great list !!!! Nice reference info.

Thank you !

Don, Thank you for your continuing knowledge, advice and support for enthusiasts. I have benefited from all of your posts here and on your website. Thankfully, you did not offer a spark plug installation procedure which has been erroneously posted in other posts and advised against by NGK.
Below is a quoted paragraph from the NGK website. Years ago I read it and since then have never used anti-seize during spark plug installation and never have a problem.
"Five Things You Need to Know About Spark Plugs
1. Anti-seize: NGK spark plugs feature what is known as Trivalent plating. This silver or chrome colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. This coating also acts as a release agent during spark plug removal. NGK spark plugs are installed at the factory dry, without the use of anti-seize. NGK tech support has received a number of tech calls from installers whom have over-tightened spark plugs because of the use of anti-seize. Anti-seize compound can act as a lubricant altering torque values up to 20 percent, increasing the risk of spark plug thread breakage."
For brevity on this post, the other 4 items can be looked up by readers of this post.
Personal experience while making repairs of mistakes by DIYers has shown, in more often cases than not, strip threads, cross threads, under or over tighten spark plugs. Too bad for them. Personally observed "certified" technicians not using torque wrenches because they are not in their personal tool kit. Oh well.
Safe travels.
