If you're dealing with engine issues on your Mercedes, this air intake temperature sensor might be exactly what you need. It replaces OE numbers 0005428418 and 0075421318, and it fits a ton of Mercedes-Benz models from 1994 up to 2021. We're talking A220, AMG GT series, C-class models, CL500, and many more - definitely check the full fitment list to make sure it works with your specific vehicle. The sensor is black plastic with 2 pins, measuring about 50x18mm, and it's built to be wear-resistant, corrosion-resistant, and able to handle high temperatures without deforming. Installation is pretty straightforward if you're comfortable working on cars - it's a direct replacement for your old or faulty sensor. This is an aftermarket part, so it's not OEM, but the quality seems solid and it comes with everything you need for installation. The air charge temperature sensor plays an important role in your engine's performance - it helps the ECU adjust the air-fuel mixture properly. If yours is failing, you might notice poor fuel economy, rough idling, or check engine lights. Replacing it can often solve these issues and get your Mercedes running smoothly again. The package includes just the sensor itself, so make sure you have any necessary tools handy for installation. For the price, it's a pretty affordable fix compared to dealership parts, and it could save you from more expensive problems down the road.
