• OE Fine Wire Double Iridium design for performance and durability
• Iridium center electrode firing pin for precise spark delivery
• Laser-welded tapered ground electrode with iridium alloy inlay
• Preset 1.1 mm gap; do not gap before installation
• Resistor plug with ceramic insulator and tapered seat
• Thread diameter: 14 mm, reach: 25 mm, hex size: 16 mm
• Heat range 8 with standard ground configuration

Product Details

The Bosch OE Fine Wire Double Iridium line is engineered for vehicles that call for an iridium-style OE replacement with a fine-wire firing tip and durable electrode construction. Bosch 96301 uses an iridium center electrode paired with a platinum-iridium and nickel-yttrium ground tip, helping maintain consistent spark quality under demanding ignition conditions. This spark plug is a direct-fit choice for many Chevrolet Colorado, GMC Canyon, Chevrolet Malibu, and Buick Envision applications, along with other GM platforms listed in the fitment data. Bosch 96301 is also referenced under previous catalog number 9611.

Common Symptoms This Part Addresses

• Rough idle caused by worn spark plug electrodes
• Hard starting from weak or inconsistent ignition output
• Misfire codes related to degraded spark plug performance
• Reduced throttle response from inefficient combustion
• Fuel economy loss tied to aging ignition components

Installation Notes

• Install only on vehicles listed in the fitment data for Bosch 96301.
• Do not gap the plug; the gap is preset from the factory.
• Verify the tapered seat and thread specifications match the original plug.
• Use the correct torque procedure for the cylinder head material and plug design.
• For service planning, confirm the original center electrode material is iridium where noted in the fitment notes.
