O2 Lambda Sensor Renault Clio Megane Dacia Duster 1.6 K4M 8200495791 AKAS

The AKAS O2 Lambda Sensor is a precision 4-wire heated replacement for Renault Clio III, Megane III and Dacia Sandero, Duster equipped with K4M 1.6-16V petrol engines, replacing OE 8200495791.

PETROL ONLY - not compatible with diesel engines. This oxygen sensor measures exhaust oxygen concentration to provide precise air-fuel ratio feedback to the ECU - critical for optimal combustion, fuel efficiency, power delivery, and emissions control on the K4M 1.6-16V engine. Premium high-temperature construction with anti-carbon and anti-corrosion coating ensures long service life. Plug-and-play 4-pin OE connector. Backed by a 6-month limited warranty.

1. 4-Wire Heated O2 - Precise Air-Fuel Ratio Control This is a 4-wire heated oxygen sensor measuring exhaust oxygen concentration for precise air-fuel ratio feedback to the ECU. Essential for optimal combustion, fuel efficiency, power delivery, and emissions compliance on the K4M 1.6-16V engine. Replaces OE 8200495791.

2. Exact OE Match - Renault/Dacia K4M 1.6 16V Petrol Only Precision direct-fit sensor for Renault Clio III (2009-2013), Megane III (2009-2016), Dacia Sandero (2009-2016) and Duster (2010-2016) with K4M 1.6-16V petrol engines. 1:1 OE dimensions, 4-pin OE connector, M18x1.5 thread - no modification, splicing, or adapter needed. PETROL ONLY - not compatible with diesel (K9K dCi) engines.

3. Fast Light-Off & Precision - Restores Performance & Clears CEL Integrated heating element brings the sensing element to operating temperature in under a minute, ensuring accurate oxygen concentration readings even during cold starts and short urban trips. Fast-response signal module transmits reliable oxygen data to the ECU, restoring optimal combustion, improving fuel economy, restoring power and throttle response, and clearing check engine lights (P0130/P0135/P0171/P0174 series) caused by a faulty or ageing sensor.

4. Premium High-Temp Construction - Anti-Carbon, Long Lifespan Premium high-temperature alloy probe with oxidation-resistant outer shell delivers reliable performance under harsh exhaust conditions. Anti-carbon-build-up and anti-corrosion surface treatment resists erosion from hot exhaust fumes, carbon deposits, and oil/PCV impurities - significantly prolonging service life vs. uncoated cheap sensors that fail prematurely from carbon fouling. Waterproof/dust-proof integrated sealing and anti-vibration internal circuit ensure consistent performance.

5. OE Quality at Aftermarket Value - 6-Month Warranty Manufactured to strict OE specifications with dependable detection accuracy, rapid signal feedback, solid high-heat tolerance, and anti-vibration capability - performing comparably to the Bosch/NTK OE sensor at a fraction of Renault main dealer cost. Backed by a 6-month limited warranty covering manufacturing defects. For South African Renault/Dacia owners - where Renault Clio/Megane and Dacia Duster/Sandero are popular affordable vehicles, and oxygen sensor failure is a common cause of poor fuel economy, rough idle, reduced power, and failed emissions/roadworthy tests.

OE Cross-Reference

Primary OE: 8200495791

Note: Verify original OE number, engine code, and sensor position (upstream vs downstream) before purchase.

1.6L PETROL ONLY - VERIFY COMPATIBILITY: This sensor fits ONLY Renault Clio III, Megane III and Dacia Sandero, Duster with K4M 1.6-16V petrol engines, replacing OE 8200495791. NOT compatible with diesel (K9K dCi), NOT with other displacements, NOT for other OE numbers. Check original OE number and engine code before purchase.

VERIFY SENSOR POSITION: This vehicle may have multiple oxygen sensors (upstream/pre-cat and downstream/post-cat). Verify the exact position (Bank 1 Sensor 1 vs Bank 1 Sensor 2) and connector type before purchase. Upstream and downstream sensors are NOT interchangeable.

4-WIRE HEATED - VERIFY CONNECTOR PIN COUNT: This is a 4-wire heated oxygen sensor. Ensure the connector has 4 pins before installation. Do NOT substitute with a 1-3 wire unheated sensor or a 5-wire wideband AFR sensor - they are electrically and functionally different and will cause incorrect readings and persistent check engine lights.

PROFESSIONAL INSTALLATION: Recommended for proper torque (30-45 Nm), correct cable routing away from heat sources and moving parts, and clearing of diagnostic trouble codes (DTCs) after replacement. Allow exhaust to cool completely (30-60 min) before servicing. Do not over-tighten. If the mounting bung thread is damaged or carbon-fouled, clean/repair before installation.

WARRANTY: 6-month limited warranty covering manufacturing defects under normal use. Does not cover improper installation, drops, contamination, water ingress, use on incompatible vehicles/engines, wrong position, modification, or normal wear. This is an aftermarket replacement part - not affiliated with or manufactured by Renault, Dacia, Bosch, or NTK.
