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

A-Premium Iridium Platinum Spark Plugs Pack of 4 are precision replacement plugs engineered for 1.6L L4 Mini Cooper engines, combining an iridium tip and platinum core for long life and consistent ignition.

This set of four fine-wire spark plugs from A-Premium is designed as a direct-fit upgrade for many Mini Cooper and Cooper Countryman/ Paceman 1.6L L4 applications (multiple naturally aspirated and turbocharged engine codes between 2007–2016). With an iridium center electrode, platinum core and a tightly controlled electrode gap, these plugs aim to deliver reliable starts, steady combustion and extended service intervals compared with conventional copper plugs. Built to the listed dimensions and thread sizes, they match OEM-style reach and hex tooling for straightforward installation.

Which Mini Cooper models and engine codes do these plugs fit?

These A-Premium plugs are compatible with a range of Mini models using 1.6L L4 engines. They cover several model years and both naturally aspirated and turbo variants when matched to the correct engine code.

• Fitment examples: Mini Cooper 2007–2008 (N14B16A), 2009–2010, 2011–2015 models including N16B16A and N14B16C turbo codes.
• Also fits Cooper Countryman and Cooper Paceman 2011–2016 where 1.6L L4 engines are specified.
• Reference numbers indicated: compatibility with 97968 and ILZKBR7B8G-style plugs.

What are the key technical specifications and why they matter?

Understanding the physical and electrical specs ensures correct fit, safe installation and reliable performance under varied driving. The materials and resistance are chosen to balance longevity and stable spark delivery.

• Center electrode: iridium tip for wear resistance and precise spark location.
• Core material: platinum for thermal stability and extended life compared to copper.
• Electrical resistance: 5000 ohms to match modern ignition systems and suppress interference.
• Physical dimensions: 12.00 mm thread diameter, 26.50 mm reach, 51 mm insulator height, 14 mm bi-hex for common tools.
• Gap range: 0.027–0.031 inches, factory-set tolerance for proper combustion.

How long can I expect these plugs to last and when should they be replaced?

Iridium and platinum combinations are selected to stretch service intervals versus standard plugs. Replacement timing depends on driving habits, fuel quality and operating conditions, but recommended intervals give a practical maintenance target.

• Suggested replacement: every 80,000–100,000 miles for optimal performance and longevity.
• Inspect sooner if you notice misfires, rough idle or increased fuel consumption.
• Always check gap before installation and use proper torque per vehicle manual.

Will these plugs install easily and what tools or checks are needed?

The plugs are manufactured to match OEM thread and hex sizes, so installation is straightforward with basic hand tools and standard precautions. Proper gap, thread engagement and torque are important to avoid damage and ensure correct sealing.

• Use a 14 mm bi-hex socket and a torque wrench to vehicle manufacturer specs.
• Confirm the 0.027–0.031 inch gap before fitting; adjust only if necessary and per instructions.
• Apply anti-seize only if recommended by vehicle guidelines; avoid over-tightening to protect threads.

Who is this for: Drivers and independent technicians who own or service Mini Cooper, Cooper Countryman and Cooper Paceman models equipped with 1.6L L4 engines and who want a durable, OEM-compatible spark plug option. These A-Premium iridium-platinum plugs suit owners seeking longer intervals between changes, stable ignition under varied load, and a direct-fit replacement that matches factory dimensions and resistance requirements.
