Fixed my emission issues right away. The sensor reads accurately and has held up through 3,000 miles so far. Fast shipping and good packaging.
The delivery of this NOx sensor was outstanding. It reached me promptly, securely wrapped, and ready for immediate installation.
I'm amazed at the shipping of this sensor for my Mercedes-Benz ML and GLE. It got here in no time, and the packaging ensured it was free from any damage. Excellent service!
The customer service is awesome. They answered all my questions about the Chevy NOx sensor quickly and clearly.
Good quality, 3 months still working great. Truck runs very smooth now and no check engine light. Very pleased.

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

Impressed by the quality of these mirrors for my CBR600F4! The build is solid, they look sleek, and installation was a breeze. Highly recommend!

Impressed by the sun visor for my Highlander! Solid build, the gray color matches well, and the light is a handy addition. A great buy!

The BMW charge pipe hose got here in no time, securely wrapped and ready to install. Great service!

I’m amazed by the quality of this adapter. It’s sturdy, easy to install, and has kept my check engine light from coming back on.

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.
