    Description

    This is  (1) O2 sensor adapter / extender 18mm thread size for sale
    This 35mm long gas saving extender works by moving the sensor further away from the exhaust flow by installing it with your front o2 sensor, the sensor and ecu would lean out the A/F(air fuel) ratio enough to save 5%~7% on your gas bill.
    Easy 10~15 mins installing job, comes with instruction and tech support
    These also might help
    to get a correct reading to prevent trouble code by
    gaping out
    the oxygen sensor away from your catalytic converter,
    header, or test pipe to reduce
    exhaust flow
    but If you want a for sure fix, I also have the correct longer / angled version, please contact me and I'll list those for your need
    Vehicle with V6 V8 V10 Engine and Dual Exhaust will need Two (2) units
    This is a clearance sale due to minor defects, price is cheapest best deal any where!!
    I ONLY ACCEPT PAYPAL and I do not ship outside of U.S.A
