Solved my P0042 permanently. The spacer positions the sensor perfectly to mimic catalytic converter readings. No more annoying CEL during emissions tests.
Amazed by the shipping speed! This O2 sensor spacer for my Tacoma showed up promptly, snugly wrapped, and ready to use right away.
This universal O2 sensor adapter spacer with mini cat is of great quality. It's sturdy, installs easily, and effectively fixes codes like P0420. So glad I bought it!

Price is great and they work ok

Purchased this kit for a china pit bike I got for free.

Fast Delivery, Good Packaging

Engine light is now off.

Fit very nicely, it fit like a factory one and the craftsmanship it very detailed. Would highly recommend Walker products.

Everything worked very well. Before attempting installation, be sure to check if the wrist pin is installed in the piston and connecting rod. I will continue to purchase parts from this brand.

Easy swap, works flawlessly on my bike. This replacement has outlasted the OEM starter.
