Denso 09-09 Subaru Impreza/08-09 Subaru Legacy GT Limited/08-09 Subaru Legacy GT spec.B/08-09 Subaru Outback Air- Fuel Ratio Sensor 234-9035

• Tarnish-proof platinum electrodes provides longer life and maintains accuracy
• Quick-response planar zirconia element can quickly detect oxygen concentration
• Measures A/F ratios from approximately 12:1 to 19:1
• Increased performance by mapping a/f ratios throughout rpm range
• Reduces emissions by keeping the air-fuel mixture at an optimum ratio
• Reduced fuel consumption and maximizes catalytic converter life
