Revainrating 5 out of 5

Keep Your Car Running Smoothly

The ACDelco restriction indicator is a must-have tool for any automotive enthusiast.Its simple design makes it easy to install and its accurate readings make it easy to know when a filter needs to be replaced. The pros outweigh the cons as it can save car owners money in the long run by avoiding costly engine repairs. The only downside is that it's not compatible with all types of filters so be sure to check before purchasing..

Cons
