As a CAR enthusiast, I've tried my fair share of exterior car accessories. Based on my experience, the Standard Motor Products ALS238 Sensor is a game-changer .It's incredibly easy to install and provides accurate readings of various engine systems. i've noticed an improvement in my car's fuel efficiency since using this sensor. The only downside is that it`s a bit pricey compared to other options on the market. Overall, if you're looking to up your automotive game, this sensor is a must-have!
