02 Sensor
Ordered the oxygen sensor and received it in 2 days and at only $30 it was worth the money compared to other websites charging $80+ for the same type of sensor. Was very easy to install even came with anti seize, turned the car on and it worked great! No more check engine light and at half the price worth it. Highly recommend for Hyundai Santa Fe 2.4L 2002
