AEM's wideband UEGO air/fuel ratio sensor kit includes a Bosch 4.2 LSU Wideband UEGO sensor, connector plug, pins and plugs, and mild steel O2 bung. This kit is designed to be an installation kit for a sensor used with an AEM wideband air/fuel UEGO controller.

These sensors have a laser-etched, calibrated resistor in the sensor’s connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor’s output. The wideband sensor is laboratory-calibrated at the Bosch factory, accurate to 0.1 AFR and never requires free-air calibration when used with an AEM wideband AFR controller.


Features:
  • Accurate to 0.1 AFR
  • Never requires free-air calibration when used with an AEM Controller and connector plug.
  • Specifically designed for use with AEM Wideband UEGO controllers
  • Includes sensor, weld-on bung, connector, wire seals and pins

This starter was sold at a great price. I was kinda Leary on buying it at the price advertised at but went with it. It bolted right up and have had no problems with it.

If you have a 2001 Dodge Ram 2500 24v 5.9 Cummins, buy it.! But read my review to the end.
Style: 17548N
So far, so great.! Put this in my 2001 Dodge Ram 2500 24v 5.9 Cummins. Bolted right up and fit perfectly. The small ground wire placement was different, a post and screw, instead of a post bolt and nut. But no problem there. I'll tell you what, I've never heard my engine turn over so quickly. This bad boy is torquey and fast.! Says it has a year warranty, and I will immediately update if there are any changes whatsoever.! The main reason I wanted to make this review, is because of how few reviews this has. And trust me, buy this starter, and rebuild your old ORM one for backup. The Delo starters are cheap to rebuild, and last forever.! I highly recommend buying, and i hope your luck is as good as mine.!?

Perfect fit for my 2018 Civic—easy, affordable, and worth it
Size: 9.5" x 10.9" x 2.1"
I’ve bought this cabin air filter multiple times for my 2018 Honda Civic, and it’s consistently great quality. It fits perfectly and is super easy to install—takes just a few minutes to swap out, and I always do it myself. Way cheaper than going to a shop or dealership. The airflow is smooth, there’s no smell at all, and it keeps the inside of my car feeling clean and fresh. No weird odors, no dust blowing in—just a solid, dependable filter that does its job well. This is the only one I’ll keep buying.

Do it mayne
Size: 9.5" x 10.9" x 2.1"
Good quality and fit but find it funny that the instructions with the air flow are on the side. I assume that would be facing out and was annoyed when I tried to close and it didn’t fit. Probably should have read the directions. Still would recommend
