Description

The Bosch 17025, also known by part number AWP-8004, is a genuine OE brand wideband lambda oxygen (O2) sensor designed for precise air/fuel ratio monitoring. It employs the advanced LSU 4.9 sensing element, ensuring accurate readings for optimal engine tuning and performance. This sensor is specifically compatible with HP Tuners CORE Engine Harnesses (COR-HAR-001 and COR-HAR-002) and EFI Connection Brand Harnesses for HP Tuners CORE ECUs. It is important to note that an HP Tuners CORE ECU requires two lambda sensors for operation, and this listing provides only one. The Bosch 17025 is a direct replacement for Holley part number 554-155 and is suitable for use with aftermarket high-performance wideband kits. Its reliable and durable construction ensures consistent performance and optimal fuel efficiency for your vehicle.
