When you are buying parts for your car, do you buy the cheapest that you can find? That is exactly what I did for years. When I installed new filters, I would choose the cheapest filter I could find and quickly put it in my car. After talking with my mechanic, I found that this was not the best practice when it comes to filters and many other parts. I created this blog to help others understand why the cheapest parts are not always the best parts for your car. Hopefully, you will make the same changes that I did to actually save yourself money in the long run.
