- Improve Fuel Economy: Marsflex oxygen sensor helps optimize fuel efficiency by providing accurate real-time data to your engine’s ECU, ensuring the ideal air-fuel ratio (14.7:1). Over time, old sensors degrade, causing incorrect fuel mixtures (too rich or too lean). Replacing them with a high-precision Marsflex sensor restores proper combustion, potentially improving fuel economy by 5-15% while reducing emissions. For best performance, we recommend replacement every 60,000–80,000 km

For a quarter of the price from a big box auto parts store I managed to include all of my maintenance parts in the budget for just the o2 sensor. Had a terrible hesitation on acceleration with misfire cels, once installed there was an immediate night and day difference. Gti is running as it always had again. Will need to replace the downstream sensor as well but the immediate improvement is enough for me to buy from this store again. Thank you!

Had a code P2197 , Bank 2 sensor 1 O2 sensor stuck lean. Replaced with this sensor and truck running good again.
Will need a 22mm offset o2 sensor socket to make installation go smoother.

I got put on and need the picture if have Ford f150 it going to have a challenge it’s few inches shorter, it can be do and you need to zip tie it the best you can way from the hot exhaust.. the extra 3 inches makes a difference, I will repost in 3 to 4 weeks let you about the durability..
I do like the adjustable rubber pieces around you to zip tie and secure it well.
The value will come in time .
It was easy to use and replace.
