For 01-04 Toyota Sequoia Tundra Upstream Downstream 02 O2 Oxygen Sensor New 4Pcs

Poor fit on Gen 1 Tundra
The front sensors fit my '03 tundra, but the downstream rear O2 sensors did not fit at all. they look similar out of the box, but the spacers were too large to accommodate the heat shields and the sensor head is a bit longer than the old OEM sensor. I altered the heat shields with my grinder and installed them anyway, but it's a poor fit, and the trouble codes are back on all 4 sensors. Disappointed
