Bosch 96353 Spark Plug

Bosch OE Fine Wire Double Iridium Spark Plug

Bosch 96353 is an OE Fine Wire Double Iridium spark plug built for modern Toyota and Lexus engines that call for precise ignition performance and long service life. Its fine-wire center electrode, laser-welded ground electrode, and iridium-alloy firing pin are engineered to deliver consistent spark quality under demanding driving conditions.

Key Features

• OE Fine Wire Double Iridium design for stable ignition performance
• Fine wire center electrode improves ignitability
• Laser-welded tapered ground electrode for precise spark delivery
• Iridium-alloy center electrode firing pin for durability
• Iridium-platinum ground electrode tip material for extended service life
• Resistor plug with 6000 resistance rating
• 12 mm thread diameter, 14 mm hex size, flat seat, projected insulator
• Pre-gapped to .8 for applications that specify this setting

Product Details

The Bosch OE Fine Wire Double Iridium line is built around a fine-wire electrode architecture that supports reliable ignition in late-model fuel-efficient engines. Bosch 96353 uses a copper core center electrode, ceramic insulator, nickel ground electrode core, and a J-gap configuration to help maintain consistent combustion characteristics. This spark plug is a direct-fit style for many Toyota and Lexus applications, including Toyota Camry, Corolla, Prius, RAV4, Highlander, Sienna, Venza, and Lexus ES, NX, RX, and UX models listed in the fitment data.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Hard starting caused by worn or eroded spark plug electrodes
• Rough idle from inconsistent spark delivery
• Misfire conditions related to degraded ignition performance
• Reduced throttle response from weak combustion events
• Service intervals affected by plug wear in high-mileage engines

Installation Notes and Tips

Verify engine application before installation using the vehicle’s service information and the listed fitment. Bosch 96353 is a 12 mm, flat-seat spark plug with a .8 pre-gap, so confirm the specified gap and torque procedure for the engine before final installation. Inspect ignition coils and plug wells for wear, oil intrusion, or contamination while servicing the plugs.
