First, depending on your car model, replacing your cabin air filter is VERY easy. With that out of the way, the shop wanted to charge almost 65 dollars to replace my cabin air filter. Decided to just buy one and do it myself. The only downside of waiting is that the air inside the car is not as fresh/clean when you're running your air. Anyways, you can usually get these kinds of filters between 20-45 dollars from auto part shops depending on the brand and features. I've used this brand and filter for the past 3 replacements on my car and they last just as long and filter just as well from my experience. No issues installing, and does in fact do a good job of filtering outside odors. Highly recommended for the price!

Not good.

Do not fit properly at all. It's loose and wobbly and that is not good.

I purchased the Front Center Console Cup Holder as a replacement and it worked perfectly. The fit was very good and it matched the interior of the car nicely. It feels sturdy and holds cups securely without them moving around while driving. Installation was simple and took just a few minutes. It’s a great solution if your original cup holder is broken, worn out,
