Bosch OE Fine Wire Iridium Spark Plug FR8TI332
Bosch FR8TI332 is an OE Fine Wire Iridium spark plug built for direct ignition performance and long service life. It uses an ultra-fine wire iridium center electrode firing pin to support consistent combustion, stable starts, and reliable engine response in the applications listed below.
Key Features
- OE Fine Wire Iridium design for OE-style ignition performance
- Ultra-fine wire iridium center electrode firing pin
- Platinum-iridium center electrode tip material
- Platinum-iridium and nickel-yttrium ground electrode tip materials
- Resistor spark plug with 5000 ohm resistance
- Projected ceramic insulator for controlled spark exposure
- Flat seat, 14 mm thread diameter, 16 mm hex size
- Preset 1.25 mm gap; do not gap before installation
Product Details
The Bosch OE Fine Wire Iridium line focuses on OE-level ignition geometry and durable electrode materials. FR8TI332 uses an iridium firing pin at the center electrode, along with platinum-iridium and nickel-yttrium materials at the ground side, to maintain spark consistency under normal engine operating conditions. The 8 heat range, projected insulator, and flat-seat design match the specifications called for in the listed Ram, Dodge, Chrysler, and Jeep applications. This part number, FR8TI332, is a direct-fit spark plug for engines that specify a preset gap and OE Fine Wire Iridium construction.
What It Helps Address
- Hard starting caused by worn or eroded spark plug electrodes
- Rough idle from inconsistent ignition firing
- Misfire conditions related to degraded spark delivery
- Reduced throttle response from weak combustion events
- Maintenance intervals where OE-style iridium plugs are specified
