Description

This DENSO Air / Fuel Ratio Sensor fits your 2012, 2011 Acura RL (Upstream) and is perfect for a tune up or performance upgrade.

• REDUCE EMISSIONS: The DENSO Air/Fuel Ratio Sensor (AFR) is one of the most sensitive components on your car engine. The sensor measures the air-to-fuel mixture in the exhaust stream under a wide range of driving conditions and sends information to the engine management computer to make adjustments based on driving conditions. This sensor reduces fuel consumption and emissions, and maximizes catalytic converter life by keeping the air-fuel mixture at an optimum ratio
• MAINTAIN ACCURACY OVER TIME: This DENSO AFR sensor provides much finer control of air/fuel mixtures in varied operating conditions and enables the fuel injection and engine timing to work more efficiently. Tarnish-proof platinum electrodes extend the life of the sensor while the DENSO aluminum-oxide trap layer prevents damage to the electrode. Damage-tolerant stainless steel construction, watertight housing, and a porous PTFE filter prevent particulates from seeping into the casing
• RELY ON QUALITY AUTO PARTS: From the development of direct ignition coils to revolutionizing the concept of the aftermarket performance spark plug by using platinum and iridium, DENSO is often on the front lines of product advancement
• TRUST IN DENSO: The automotive industry has recognized the DENSO commitment to quality through such prestigious awards as the Deming Award for Quality, the J.D. Power and Associates Chairman’s Award, and numerous supplier awards for quality
