HOAVEED LSU 4.9 Wideband O2 Sensor 5-Wire – AEM/X-Series Compatible, Bosch 17025 Replacement

HOAVEED's LSU 4.9 wideband O2 sensor is a direct-fit 5-wire UEGO replacement engineered to work with AEM 30-4110, 30-0300, 30-0310 and X-Series AFR controllers while replacing Bosch 17025/0258017025.

This high-temperature oxygen sensor provides fast, stable air-fuel ratio readings for tuning, diagnostics, and performance monitoring. Built around Bosch LSU 4.9 sensor technology, the HOAVEED unit is manufactured to match the electrical and physical characteristics required by mainstream wideband controllers, making it a straightforward swap on many vehicles and aftermarket AFR systems. It’s offered with a 12-month warranty and designed for repeated duty in hot engine bays.

Will this sensor plug into my AEM X-Series or AEM wideband controller?

Yes — the HOAVEED LSU 4.9 is wired and calibrated to the same standards used by AEM for the referenced models, enabling plug-and-play installation without controller reconfiguration in most cases. Confirm connector type and cable length before ordering to avoid fitment issues.

• Compatible with AEM part numbers 30-4110, 30-0300, 30-0310 and X-Series AFR inline controllers
• Uses the 5-wire LSU 4.9 electrical layout expected by AEM devices
• Check sensor plug style and lead length for your installation

How does this replace Bosch 17025 or 0258017025 sensors?

This HOAVEED unit matches the physical thread size, heater circuit and signal wiring used by Bosch 17025-style widebands, providing equivalent function in most systems designed for that Bosch part number. It’s intended as an OE-style spare that restores accurate AFR feedback without modifying the controller harness.

• OEM-style thread and hex size for standard wideband bung installations
• Equivalent heater and signal connector layout to Bosch 17025
• Designed for direct replacement—no additional adapters required in typical setups

What vehicles is this unit compatible with?

The sensor fits many popular gasoline engines where a wideband Bosch-style LSU 4.9 is used, including various Ford, Honda, Toyota and BMW models across model years listed by manufacturers. Always verify the original sensor type and wiring in your vehicle or aftermarket harness before purchase.

• Common fits: Ford Escape, Fiesta, Focus; Honda Accord, Odyssey; Toyota Camry, Corolla, RAV4
• Also used in many BMW models (e.g., 128i, 328i, 335i, 525i, X3, X5) and some Chevy applications
• Works broadly with engines requiring a 5-wire LSU 4.9 wideband sensor

How durable and maintenance-friendly is the sensor?

HOAVEED builds this wideband with high-temp materials and robust internal components to tolerate repeated thermal cycles and exhaust exposure. Routine checks of the plug and wiring for corrosion or damage are recommended to maintain accurate AFR readings and longevity.

• High-temperature resistant construction suited for engine bay environments
• Stable long-term output thanks to LSU 4.9 design and quality materials
• 12-month warranty covers defects—contact seller for replacement or refund

Who is this for: This HOAVEED LSU 4.9 wideband oxygen sensor is aimed at tuners, performance enthusiasts, and mechanics who need a reliable Bosch-style 5-wire UEGO replacement for AEM wideband controllers or direct Bosch 17025 swaps. It’s ideal when you require accurate AFR data from an aftermarket controller or want an OE-like spare without custom wiring. Be sure to confirm connector type and cable length for a smooth installation on your specific vehicle or logging setup.
