first impression when i got this sensor i was pretty skeptical cause my engine had been acting up and i needed a fix fast it arrived quickly and installing it was straightforward no tools or expertise needed which i appreciate as a beginner with cars it started working right away and the engine seems to run better now with less fuel consumption most likely but its not a huge difference very subtle honestly i dont notice anything dramatic just that the problems i had are gone for now i guess it does its job but i wouldnt say its amazing just decent if youre in a pinch it might help but dont expect miracles overall its okay not great not terrible
- Pros: it fit right into my cummins engine without any hassle which was a relief and it seems to be holding up well so far no issues with wear or anything which is good for keeping things running smoothly
- Cons: kinda meh on the performance though it does what its supposed to but i was expecting a bit more maybe it doesnt make the engine run as dreamy as advertised and the installation while easy didnt wow me just basic stuff
