Bosch 8110 OE Double Platinum Spark Plugs - Pack of 4, Pre-Gapped for OE Fit and Long Life

BOSCH 8110 OE Fine Wire Double Platinum spark plugs deliver extended service life and consistent ignition for compatible gasoline engines. These Bosch OE double platinum plugs combine a fine-wire platinum firing pin with a platinum ground inlay and corrosion-resistant threads to maintain gap integrity and resist wear over time. Engineered to match original equipment specifications, they arrive pre-gapped and ready to install, making them a straightforward upgrade when you want reliable starts and steady engine performance without extra preparation.

How do these plugs last longer than standard copper spark plugs?

The double-platinum construction reduces electrode erosion so the spark gap stays stable for many miles. Platinum is harder and more chemically resilient than copper, which slows wear from repeated sparking and combustion by-products.

• Fine-wire platinum firing pin and ground inlay minimize gap growth.
• Laser-welded construction prevents electrode separation and corrosion.
• Designed to deliver up to three times the service life versus copper plugs.

Will installation be quick and safe for my vehicle?

Yes — each plug ships pre-set to the correct gap so you can fit them directly from the box. Nickel-plated rolled threads resist corrosion and reduce the chance of galling, so removal and future servicing are easier.

• No anti-seize required thanks to nickel-plated threads.
• Pre-gapped at the factory to match OE specifications.
• Compact design fits modern gasoline engine electrodes and ignition systems.

What performance benefits should I expect after switching to these Bosch plugs?

Replacing worn plugs with double-platinum Bosch units helps maintain consistent ignitability and combustion stability, which supports smoother idling and reliable starts. Because the gap is more durable, ignition quality remains stable over longer intervals between changes.

• Improved corrosion resistance for dependable spark delivery.
• Reduced gap erosion for consistent firing characteristics.
• Meets OE fit, form, and function for compatible models.

Which cars are these Bosch 8110 plugs compatible with?

These spark plugs are designed for a range of late-model gasoline vehicles; compatibility depends on engine type and model year. Always verify fitment with your vehicle’s parts lookup or Bosch fit checker before ordering to ensure correct thread size, reach, and heat range.

• Common compatible brands include Nissan, Infiniti, Hyundai, Kia, Scion, Suzuki.
• Often used in V6 and four-cylinder engines shown in manufacturer fit lists.
• Pack of four covers many standard four-cylinder tune-up jobs.

Who is this for?

This pack of four Bosch 8110 OE double platinum spark plugs is ideal for DIY mechanics, independent shops, and fleet managers who need OE-quality replacement parts that reduce maintenance frequency. Choose these plugs if you want an easy, drop-in upgrade for cars that specify double-platinum electrodes, prefer pre-gapped parts for fast installation, and value corrosion-resistant threads for simpler future removal.
