Product Details

The Bosch MHK100940 is a high-quality front (upstream) oxygen sensor designed as an OEM replacement for Land Rover vehicles. This sensor is positioned before the catalytic converter and plays a critical role in monitoring exhaust gas oxygen levels to optimize engine performance, fuel efficiency, and emissions control.

Key Features:

  • OEM-quality oxygen sensor with exact-fit design
  • Plug-and-play installation with no splicing required
  • Heated sensor with 4-wire configuration
  • 22mm hex size for proper installation
  • Stainless steel construction for durability and corrosion resistance
  • Factory-tested to meet strict quality standards

The front oxygen sensor, also known as the pre-cat sensor, measures oxygen levels in exhaust gases as they exit the combustion chamber. The engine control unit uses this data to adjust the air-fuel mixture, ensuring optimal combustion at the ideal 14.7:1 ratio. This results in improved fuel economy, reduced emissions, and better overall engine performance. Oxygen sensors should typically be replaced every 60,000 miles to maintain peak efficiency.

Technical Specifications:

  • Manufacturer Part Number: MHK100940
  • Sensor Position: Front/Upstream (Pre-Catalytic Converter)
  • Thread Size: M18 x 1.5
  • Hex Size: 22mm
  • Connector Type: OEM-style plug
  • Wire Configuration: 4-wire heated sensor

Bosch invented the oxygen sensor and has been the industry leader in O2 sensor technology for over 40 years. Every Bosch oxygen sensor is manufactured to exacting OEM specifications and undergoes rigorous functional testing before leaving the factory to ensure reliable, long-lasting performance.

very easy page to navigate and great price, I ordered a second shipment of the same item, best price in town, thanks.

so far so good waiting for merchandise

Quick easy site to use

Placed an order with Adam on Monday, Nov 28th (#601). Very satisfied with Adam's technical knowledge and received my product on Nov 29th. The product is exactly as he represented and, because of this great customer service, I will place future orders.

Recommended by a fellow RegalGS member. Cheaper than Amazon. I haven't had the opportunity to put them on yet, but everything looks good.

Extremely easy to use your website. Everything came in as new condition and in a very quick manner. Thank you!!

Product was cheapest I could find and shipping was super fast. Not sure how you could go wrong with them.

There.was a bit of miscommunication between sales and shipping departments, but my order was filled and shipped as stated. Very low price, in fact the lowest on the net, and I did alot of research. Other than the shipping issue, I'm very satisfied and will buy more parts from them soon. Thank you!!!

Wow, cheapest price I could find anywhere. AND, it shipped the same day. Amazing service. Thanks Autoplicity!

After seeing that Autoplicity was in good standing with the BBB and had favourable reviews reported elsewhere I placed an order on a Sunday evening. On Monday morning I already had a confirmation email and order number. On Tuesday I was notified that my order had shipped. Their price of $477 on the part I ordered was about $30 cheaper than Summit Racing, who I usually do business with, and the cost of shipping and handling was only a few dollars more. I haven't recieved the part yet but have no reason to think I won't be totally satisfied with the transaction.
