A-NAFTULY Iridium Platinum Spark Plugs 4-Pack for BMW 2.0L (2012–2018) — 0.6mm Fine-Wire, Laser-Welded

A-NAFTULY Iridium Platinum Spark Plugs 4 Pack 97506 (SILZKBR8D8S) are high‑performance replacement plugs engineered for 2.0L BMW engines from 2012–2018, delivering precise ignition, extended service life, and improved fuel efficiency.

If you own a BMW with a 2.0L L4 engine from model years 2012–2018, these four A-NAFTULY iridium spark plugs are designed as a direct replacement for factory parts. They match OEM reference numbers including 97506, SILZKBR8D8S, 12120039664, 12120040573, and 12127622445, making them suitable for many 320i, 328i, 428i, X3, X4, X5, Z4 and other compatible BMW models. Built with a 0.6mm iridium fine‑wire center electrode and laser‑welded construction, these plugs prioritize reliable ignition, longevity, and efficient combustion without altering engine specifications.

Which BMW models and engines are these spark plugs compatible with?

These plugs are intended for BMW vehicles equipped with a 2.0L inline‑4 engine produced in the referenced years. They fit a range of sedans, coupes, and SUVs listed by the manufacturer as compatible applications.

• 2012–2018 BMW 320i and 320i xDrive
• 2012–2016 BMW 328i, 328i xDrive, 328i GT xDrive
• 2013–2016 BMW 528i and some 2014–2016 428i / 228i models
• 2013–2017 BMW X3 and 2015–2018 X4, X5; Z4 fitment where specified

How do these iridium platinum plugs affect performance and economy?

The 0.6mm iridium fine‑wire center electrode produces a smaller, more concentrated spark, which helps promote a cleaner burn of the air/fuel mixture. That can translate to steadier idle, more consistent throttle response, and potential fuel‑use improvements compared with worn or lower‑grade plugs.

• Fine‑wire iridium produces a focused spark for efficient combustion
• Laser‑welded construction resists electrode wear and maintains gap stability
• Durability helps preserve ignition performance across service intervals

What materials and design features make these spark plugs durable?

The center electrode uses an iridium alloy with a very high melting point and harder surface than platinum, providing stronger resistance to heat and electrical erosion. Combined with precision manufacturing and a platinum ground electrode, these plugs are built to withstand the demands of modern turbocharged and direct‑injection engines.

• Iridium fine‑wire center electrode for long life and heat resistance
• Platinum ground electrode where applicable for consistent gap wear
• Precision laser welding reduces electrode detachment and failure risk

What comes in the package and what warranty/support is offered?

The product ships as a set of four spark plugs—enough to replace all plugs on typical 4‑cylinder BMW engines. A-NAFTULY includes a 12‑month limited warranty and customer support to help resolve fitment or quality questions after purchase.

• Set of 4 iridium platinum spark plugs (reference 97506 / SILZKBR8D8S)
• 12‑month worry‑free warranty and dedicated support from A-NAFTULY
• OEM cross‑reference numbers printed for easy verification

Who is this for? These A-NAFTULY Iridium Platinum spark plugs suit BMW owners and independent mechanics who want a reliable, OEM‑compatible ignition replacement for 2.0L L4 engines (2012–2018). They’re appropriate for drivers seeking longer‑lasting spark plugs with stable ignition performance, and for anyone replacing all four plugs during routine maintenance or when restoring throttle feel and efficiency. Always verify part numbers against your vehicle’s service manual or VIN to confirm compatibility before installation.
