Essential Factors We Consider
When shopping for spark plugs, always check your engine code. Different Mini models require specific heat ranges and electrode materials.

Budget Planning
Spark plugs are relatively inexpensive but crucial. While budget-friendly options exist, spending a little more on high-quality iridium plugs can save you time and money on frequent replacements. Look for kits that include ignition coils if you suspect a deeper issue with your firing system.
