HOAVEED LSU 4.9 Wideband O2 Sensor — 5‑Wire UEGO, AEM X-Series Compatible, Bosch 17025 Replacement

HOAVEED LSU 4.9 wideband O2 sensor is a 5-wire UEGO replacement engineered to plug directly into AEM 30-4110, 30-0300 and 30-0310 X-Series AFR controllers and replace Bosch 17025/0258017025 for reliable air-fuel ratio monitoring.

This wideband oxygen sensor uses Bosch LSU 4.9 technology in a universal-fit package designed for tuners, performance shops and OEM replacements. It offers fast response, stable readings across temperature ranges, and a form factor intended to match common OE and aftermarket harnesses. The sensor suits a broad range of gasoline engines — from compact Fords and Hondas to BMW inline-sixes — when paired with a compatible wideband controller.

How does this sensor work with my AEM X-Series AFR controller?

The HOAVEED LSU 4.9 outputs a UEGO signal compatible with AEM X-Series and similar wideband controllers, allowing your gauge or ECU to calculate accurate air-fuel ratios. Wiring follows the standard 5-wire LSU pinout so installation is typically plug-and-play when the connector and lead length match.

• Direct compatibility with AEM 30-4110, 30-0300, 30-0310 and X-Series inline AFR units.
• Standard 5-wire LSU 4.9 pinout for heater, ground, reference and signal connections.
• Replaces Bosch 17025/0258017025 dimensions and thread form for OE-style fit where applicable.
• Works with most controllers that accept Bosch LSU 4.9 sensor signals.

What vehicles and applications will this wideband sensor fit?

This sensor is built as a universal fit but matches many specific OE applications where Bosch 17025-style sensors were used. It’s often chosen for engine tuning, performance monitoring and replacing failed aftermarket or factory wideband sensors in a wide range of cars and light trucks.

• Common fitments include Ford Escape, Fiesta, Focus and various Toyota and Honda models (Camry, Corolla, Accord, Odyssey).
• Compatible with many BMW models that used LSU 4.9 sensors across 2006–2013 model years (e.g., 128i, 328i, 335i, 525i, X3, X5).
• Also used with aftermarket setups on turbocharged or naturally aspirated engines requiring accurate AFR feedback.
• Confirm connector type and sensor lead length before purchase to ensure proper fit.

How durable and reliable is the HOAVEED LSU 4.9 sensor under engine conditions?

The sensor housing and internal components are designed for high temperatures and vibration typical of engine bays. Materials and construction aim to meet or exceed OEM durability so you get consistent AFR readings over time without premature failure.

• High-temperature resistant materials for the sensor tip and heater assembly.
• Robust wiring and connector designed to withstand heat and flex in engine compartments.
• Targeted long-term stability from Bosch-based LSU 4.9 measurement chemistry.
• Backed by a 12-month warranty for replacement or refund if the sensor fails.

What should I check before ordering to avoid fitment issues?

Many customers select the wrong wideband sensor because of differences in connector style and cable length. Verify both the plug type and the physical length of the sensor lead on your existing unit to ensure the HOAVEED LSU 4.9 will mate correctly with your harness and controller.

• Compare connector shape and pin count to your current sensor plug.
• Measure lead length from threads to connector to confirm reach to your controller or extension.
• Confirm your controller expects an LSU 4.9 (not older LSU 4.2 or different family sensors).
• Check thread size and bung compatibility for direct-in-place replacements.

Who is this for: This HOAVEED LSU 4.9 wideband O2 sensor is suited for vehicle owners, tuners and shops that need a Bosch-style 5-wire UEGO sensor compatible with AEM X-Series controllers. It’s a practical choice for replacing worn wideband sensors on common passenger cars and performance builds, provided you confirm connector and length compatibility before ordering. The included 12-month warranty adds a safety net for installation and early-life failures.
