So, why did I buy this? My car was acting up, and I needed a quick fix. Compared to what I used before, this one is way better—no weird noises or misfires. But honestly, it's just a sensor; it does its job, but I wish it had a bit more oomph. Most likely, it'll hold up for a while, but I'm keeping an eye on it. Not bad, not amazing. 😕
- Pros: This sensor fit perfectly into my Mazda, just like the original part, which was a huge relief. It's incredibly reliable and has kept my engine running smoothly without any hiccops, making it a solid replacement that I didn't have to fuss over.
- Cons: I expected more in terms of durability or some extra features, but it's pretty basic and doesn't offer anything beyond the standard function. It might not last as long as I hoped, given the price point.
