Replacement Spark Plugs for MINI Cooper R52 Convertible (2005-2008)
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)

What's the Difference in Aftermarket and OEM Spark Plugs?
There are many benefits to using OEM spark plugs, including:
- Longer service life
- Greater spark plug efficiency
- Greater energy with ignition sparks
- Higher wear resistance
- Better resistance to chemicals in the combustion chamber
- Greater resistance to material erosion
- Perfect flame dispersion front on all sides
HOWEVER....often time, aftermarket plugs are from the same manufacturer as the OEM (Factory Original Replacement part), they just don't carry the MINI Cooper official brand. (This is specially true with Mini Mania's Aftermarket Spark Plugs.)
Either way... we promise you're getting the best MINI Cooper Spark Plugs for sale on the market.
All current MINI models have spark plugs located at the bottom of a deep well - this requires special 'extended' spark plug sockets. On the R50, R52 and R53 models, we recommend using a six point 5/8" deep well spark plug socket to reach the deep set spark plugs on your MINI. (This socket has a 3/8" drive, is 5" long, and equipped with the expected rubber insert.)
We also recommend the use of 'locking extensions' so the socket does not get stuck on the plugs.
