Bosch FR7NPP332 Spark Plug

Bosch OE Fine Wire Double Platinum Spark Plug

Bosch FR7NPP332 is an OE Fine Wire Double Platinum spark plug built for steady ignition performance and extended service life. It uses platinum on the center electrode and a platinum inlay on the ground electrode to reduce gap erosion and maintain consistent firing characteristics.

Compatible With BMW 128i, 323i, 325i, 325xi, 328i, 328i xDrive, 328xi, 328xi, 328xi, 328xi, 528i, 528i xDrive, 528xi, 530i, 530xi, X3, X5, Z4, and Saab 9-3 applications listed below. Bosch FR7NPP332 is a direct OE-style spark plug choice for drivers replacing factory double platinum plugs on select BMW and Saab engines.

• OE Fine Wire Double Platinum construction
• Platinum center electrode tip for durability
• Platinum ground electrode inlay to help limit wear
• Resistor design for stable ignition performance
• Preset gap; do not gap before installation
• Flat seat, 14 mm thread diameter, 16 mm hex
• Heat range 7 with ceramic insulator

Product Details and Design

The Bosch OE Fine Wire Double Platinum line is engineered around original equipment spark plug specifications. FR7NPP332 uses a fine-wire platinum firing pin at the center electrode and platinum at the ground electrode, which helps preserve the gap over time and supports consistent spark delivery. The plug also features a copper and nickel-ytttrium core structure, a standard ground configuration, and a 6000 ohm resistor for controlled electrical performance. This makes it a practical replacement for BMW and Saab engines that call for a double platinum plug with a preset gap.

What This Spark Plug Helps Address

• Hard starting caused by worn spark plug electrodes
• Rough idle from inconsistent ignition output
• Misfire conditions related to plug wear
• Loss of fuel efficiency from degraded spark quality
• Service intervals shortened by rapid gap erosion
