BOSCH 96337 Double Iridium Spark Plug Pack of 4 - Long Life

In this review the BOSCH 96337 Double Iridium spark plugs are evaluated for modern gasoline engines and drivers who want longer service life and reliable ignitability. The bottom line is that these plugs are aimed at owners of compatible Acura, Chrysler, Dodge, Honda, Jeep, Ram, and Volkswagen models who value long-lasting ignition performance and hassle-free installation. They stand out for their double iridium construction and pre-gapped, OE-matched design that lets users install and drive without extra adjustments.

Key Features

• Double iridium electrodes: The iridium firing pin and iridium ground inlay provide enhanced durability and longer service life compared to standard copper plugs.
• Ultra-fine wire firing pin: The 360-degree laser welded ultra-fine wire improves ignitability and lowers voltage requirements for more consistent starts and smoother idle.
• Pre-gapped at factory: Ready to install out of the box with no gap adjustment required, saving time during routine maintenance.
• Nickel-plated rolled threads: Threads resist corrosion and eliminate the need for anti-seize, simplifying installation and future removal.
• OE-matched fit: Designed to meet or exceed original equipment design for modern gasoline and GDI engines, ensuring proper fit and function.
• Pack of 4: Supplied as a set of four plugs to cover typical 4-cylinder service intervals or partial replacement needs.

Who It's For

These spark plugs are best for drivers of compatible models who prioritize durability and reliable ignitability, including many Acura, Honda, Jeep, Dodge, Chrysler, Ram, and Volkswagen vehicles. Owners who prefer OE-matched parts and want to avoid gap adjustments or thread anti-seize will find these especially convenient.

Drivers with older engines that do not require iridium-level performance or those who need plugs for non-listed models should verify fitment before purchasing. Professional installers or DIYers who need a specific heat range not listed here should consult manufacturer fitment details.

Pros & Cons

Pros

• Longevity from dual iridium construction gives up to 4X longer life versus copper plugs.
• Improved ignitability from the ultra-fine wire reduces voltage demand and can smooth starting.
• Factory pre-gap and nickel-plated threads make installation quick and corrosion-resistant.

Cons

• Higher upfront cost than basic copper or single electrode plugs, although longevity offsets this for many users.
• Fitment varies by engine; buyers must verify exact vehicle compatibility before ordering.
