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 catalytic converter set for my 2010 Jeep Wrangler is outstanding. Sturdy build, perfect fit, and it's kept my engine running clean and efficient.

I’m really impressed with the quality of these connectors. They fit perfectly, are durable, and have made my 2007 Mountaineer run smoothly.

I'm extremely satisfied with the quality of these injectors. Sturdy and reliable, they've made my 2012 Mule run smoother than ever.

Excellent resolution for the Check engine Light.

Installation was a breeze, thanks to the kit's comprehensive design and clear instructions.

The new ignition module was installed without major issues, though the spark plug wires were uniform in length, unlike the original OEM part which had one longer wire to reach the farther spark plug. With this replacement, the wire barely made it to the distant spark plug, while the coil for the closer one had to be looped over the engine. Another challenge was connecting the reverse plug and another connector the module's male terminals were round, while the snowmobile's connectors had square holes. This made the connection difficult, requiring some wiggling to fit the round pins into the rectangular slots. Despite these minor fitment issues, the snowmobile started on the first pull and is running smoothly with the new module. Hopefully, it will prove durable over time.

These Magneto Stator Rectifier Gasket Set totally exceeded my expectation. They provides a reliable power upgrade to my bike's electrical system. The only problem is it takes too long to get it. But anyway, it works great.

Fit well

This product works well. When I installed this eliminator, the B2 catalytic converter for my 2016 3.7L Ford PIU was priced at $1,400. I had previously installed the same part on my 1998 4.0L Jeep Wrangler, and it has been performing great. Only time will tell if it holds up long-term, but I hope I can find replacement cartridges if needed. The delivery was delayed by two days due to the UPS-to-USPS handoff.

Definitely would buy again if ever needed. Plug and play, no programming needed.
