A-Premium Iridium Platinum Spark Plugs for Mini Cooper 1.6L L4 — Pack of 4, Fine-Wire Durability

A-Premium Iridium Platinum spark plugs (pack of 4) are precision-engineered ignition components for 1.6L L4 Mini Cooper engines, combining an iridium tip with a platinum core for reliable firing and extended service life.

These spark plugs are designed specifically to match the fitment and performance needs of various Mini Cooper and Cooper Countryman/Paceman 1.6L engines (engine codes including N14B16A, N16B16A and N14B16C). The fine-wire iridium tip improves ignition consistency while the platinum core supports durability; combined they offer a balance of stable combustion, long replacement intervals, and OEM-compatible dimensions.

Will these plugs fit my Mini Cooper 1.6L engine?

Yes — the A-Premium pack of four is intended for a range of 1.6L L4 Mini Cooper models across model years listed in the fitment data. Check your engine code and the plug thread/reach specifications to confirm exact compatibility before ordering.

• Compatible with Mini Cooper 2007–2015 (various N14/N16 engine codes)
• Also fits Cooper Countryman and Paceman 2011–2016 variants where specified
• Matches thread diameter 12.00 mm and reach 26.50 mm for correct seating
• Hex size: 14 bi-hex — use the proper socket for installation

How do these iridium-platinum plugs affect ignition and fuel burning?

The iridium center tip provides a small, durable contact point that helps create a stronger, more concentrated spark, while the platinum core contributes to steady performance over time. Together they promote consistent combustion cycles, which can help the engine run smoothly under varying loads.

• Fine-wire iridium tip reduces required voltage for a reliable spark
• Platinum core resists wear and maintains the electrode profile
• 5000 ohm resistance built in to help suppress electrical noise
• Specified gap 0.027–0.031 in helps ensure consistent firing

What are the measurable specs I should know before buying?

Dimensions and electrical resistance matter for fit and function: these plugs have a 12.00 mm thread diameter, 26.50 mm reach, and a 51 mm insulator height. The integrated resistor is rated at 5000 ohms, and the electrode materials are iridium for the tip and platinum for the core.

• Thread diameter: 12.00 mm for correct engine threading
• Reach: 26.50 mm to match combustion chamber depth
• Insulator height: 51 mm for proper boot clearance
• Hex size: 14 mm bi-hex for trusted tool compatibility

How often should I replace these spark plugs?

A-Premium iridium-platinum plugs are built for longevity; replacement intervals are much longer than traditional copper plugs. For routine driving conditions, plan on inspecting and replacing them in the 80,000–100,000 mile range, or sooner if diagnostics indicate misfire or poor combustion.

• Recommended service interval: 80,000–100,000 miles under normal use
• Replace earlier if the engine shows misfires, rough idle, or check engine lights
• Use proper torque and anti-seize practices during installation
• Verify gap remains within 0.027–0.031 in when installing

Who this is for: drivers and mechanics who need direct-replacement spark plugs for Mini Cooper 1.6L L4 engines and want longer service life than standard copper plugs. These are appropriate for DIY installers who can confirm engine code and measurements, as well as professional shops seeking a cost-effective iridium/platinum option for routine tune-ups. Always cross-reference your vehicle’s service manual and engine code before purchasing to ensure exact fitment.
