These sensors were a direct fit, my gas mileage went up, and my check engine light turned off. Definitely worth the money.

Worked Great on my LS Swap

Wouldn’t go to ready status. Volts fluctuated around .45 and couldn’t achieve closed loop. Swapped with Bosch sensors, and the difference was staggering. Goes to show that cheap O2 sensors are almost never worth it. Both bad.

product is not compatible with my '04 GMC 4.8L as stated. Connectors were different. Gave 3 star because refund was hassle free.
