Bosch 96315 OE Fine Wire Double Iridium Spark Plugs – Pack of 4

Bosch 96315 OE Fine Wire Double Iridium Spark Plugs

Experience ignition precision and long-lasting performance with Bosch OE Fine Wire Double Iridium Spark Plugs. Built for modern gasoline engines, including those with Gasoline Direct Injection (GDI), these plugs combine an ultra-fine wire design with iridium electrodes to support efficient combustion, smoother starts, and durable operation. They come pre-gapped and feature nickel-plated rolled threads, making installation straightforward right out of the box. This pack of four is designed to help you replace all plugs at once to maintain consistent ignition behavior across cylinders.

Key benefits at a glance

• 360-degree laser-welded ultra-fine wire iridium firing pin delivers better ignitability and enhanced durability, potentially reducing ignition voltage requirements by up to 24%.
• Iridium center electrode and iridium ground electrode inlay support consistent spark performance and longer wear life, claimed to be up to 4x longer than standard copper plugs.
• Nickel-plated rolled threads resist corrosion and do not require anti-seize, simplifying installation and minimizing threading issues.
• OE-matched design ensures proper fit, form, and function for modern engines, including those using GDI technology.
• Factory pre-gap means you can install the plugs without additional gap adjustments, saving setup time.
• Packed as a four-pack to enable balanced replacement across all cylinders for uniform performance.

Installation and maintenance tips

• Confirm your vehicle’s compatibility using the fit guide or checker before installation.
• When replacing, install all four plugs to maintain even ignition timing and combustion quality.
• Follow standard torque specifications for your engine to avoid overtightening or under-tightening.

Real-world use scenarios

In daily driving, these plugs may contribute to crisper throttle response and steadier idle by promoting precise combustion. On longer trips or when demand on the engine increases, the iridium construction is designed to help resist wear, supporting reliable starts and smooth engine operation over time. While results can vary by vehicle and driving conditions, the design aims to provide durable performance and consistent ignition for modern powertrains.
