Bosch OE Fine Wire Double Iridium Spark Plug 9601
Bosch 9601 is an OE Fine Wire Double Iridium spark plug built for direct-replacement ignition service on a wide range of GM, Buick, Pontiac, Cadillac, Oldsmobile, and select Ford applications. It uses a fine-wire iridium center electrode and a laser-welded tapered ground electrode to promote consistent spark delivery, stable combustion, and long service life.
OE Fine Wire Double Iridium Design
The Bosch OE Fine Wire Double Iridium line is engineered around OE-style fit and electrode durability. This plug uses an iridium-alloy center firing pin, an iridium-inlay ground electrode, and a tapered ground tip design to improve ignitability while maintaining the long-life characteristics expected from an OE replacement spark plug. Part number 9601 is a resistor-style, 4-cycle spark plug with a preset gap; do not gap it during installation.
- Fine-wire iridium center electrode for precise spark initiation
- Laser-welded tapered ground electrode for durability and stable firing
- Preset gap; do not adjust before installation
- Resistor design for ignition system noise control
- OE-style replacement for select Chevrolet Silverado 1500, GMC Sierra 1500, and Buick applications
- Compatible with tapered seat applications using a 14 mm thread and 16 mm hex
Detailed Product Overview
Bosch 9601 is designed for vehicles that originally used iridium, platinum, or copper/nickel spark plugs, depending on the application. The double-iridium construction helps maintain electrode integrity under repeated heat cycles, while the ceramic insulator and nickel-yttrium/copper core materials support consistent performance. This spark plug is a direct-fit ignition service part for many 1995-2014 GM platforms, including Chevrolet Express 1500, Chevrolet Silverado 1500, GMC Savana 1500, GMC Sierra 1500, Buick LaCrosse, Pontiac Grand Prix, and related models listed in the fitment data.
