Are OEM Mazda Oxygen Sensors Better Than Aftermarket?

If you're looking for a new oxygen sensor for your Mazda, you might be considering an aftermarket replacement. Read on to learn about some excellent reasons to stick with a genuine OEM Mazda O2 sensor, and find some pointers on where to find high-quality OEM parts at the best prices.

OEM Oxygen Sensors Are Designed And Engineered For Your Vehicle

Your Mazda engine relies on precise data from the oxygen sensors to ensure the best fuel economy, peak engine performance, and low tailpipe emissions. The engine ECU is programmed and optimized for the original OEM oxygen sensors. Every Mazda O2 sensor is engineered and calibrated to work best with specific Mazda engines.

OEM sensors are sized to fit tight clearances and plug directly into the factory harness without modifying the connector. Some companies do supply OEMs directly. However, their own branded aftermarket parts may not necessarily be an equal counterpart to the OEM version. In a nutshell, aftermarket oxygen sensors can be hit or miss in terms of quality, reliability, and fit.

OEM Oxygen Sensors Cost Less Over Time

The reliability of aftermarket O2 sensors can be spotty, at best. Oxygen sensors are subjected to high heat and environmental stress over their lifetime. This is why quality engineering and manufacturing of these sensors are crucial. Searching online, it doesn’t take long to discover that aftermarket O2 sensors can be troublesome and unreliable.

We often have good intentions by trying to save money on inexpensive parts. The harsh reality is that we often end up spending more money over time. Frequently replacing a cheap part ends up costing much more than buying a high-quality, reliable part that lasts. 

OEM Oxygen Sensors Are Easier To Buy

Finding the correct aftermarket oxygen sensor for your car can be complicated. There are countless aftermarket manufacturers, and you’ll need to spend a lot of time researching prices, warranties, and reviews for all of the O2 sensors available. Aftermarket manufacturers assign their own part numbers across their product lines. You’ll need to identify your old part and cross-reference their part number with the OEM part number to ensure the correct purchase. The aftermarket part number may cover many applications and not be an exact match for your vehicle and engine.

Purchasing a genuine OEM Mazda oxygen sensor is as simple as searching our website or giving us a call. If you have the part number of your current O2 sensor, we can immediately identify the exact replacement. If the part number has changed, Mazda has likely improved the sensor to perform even better than the original. OEM Mazda oxygen sensors come with a full 12-month warranty. Should you need a warranty claim during that time, simply give us a call.
