• Manufactured to match OEM thread size and heat range for direct replacement.

How do A-NAFTULY iridium plugs affect fuel efficiency and performance?

Their 0.6mm iridium fine-wire center electrode promotes a stronger, more focused spark that helps achieve cleaner combustion and can improve throttle response. Laser-welded construction reduces electrode erosion, which helps maintain ignition consistency and may support steady fuel economy over time.

• Fine-wire 0.6mm iridium tip for concentrated spark energy and efficient burn.
• Laser welding ensures a stable electrode bond and reduced wear.
• Designed to maintain ignition performance across many miles, helping consistent MPG.

What are the durability advantages of iridium and platinum in these plugs?

Iridium alloy offers a much higher melting point and harder surface than conventional alloys, which resists electrical and thermal wear. Combined with a platinum-enhanced design, these plugs are built to last longer between service intervals compared with standard copper plugs.

• Iridium center electrode is significantly harder and more heat-resistant than platinum alone.
• Platinum elements help stabilize firing characteristics and reduce erosion.
• Longer electrode life reduces frequency of replacements and service downtime.

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

The product ships as a set of four spark plugs, sufficient for a typical 4-cylinder BMW engine. A-NAFTULY includes a 12-month warranty and customer support to assist with fitment questions or replacement concerns.

• Pack includes 4 A-NAFTULY Iridium Platinum spark plugs (97506 / SILZKBR8D8S).
• 12-month worry-free warranty backed by A-NAFTULY customer support.
• Installation guidance and fitment references included to verify vehicle compatibility.

Who is this for: These spark plugs are suited for BMW owners and DIY mechanics who want a durable, OEM-compatible ignition upgrade for 2.0L L4 engines (model years 2012–2018). They are ideal if you seek longer-lasting electrodes, consistent combustion, and a direct-fit replacement that follows factory specifications without aftermarket modification.
