    Keeps the old beater out of the shop
    By  One Crank to Another,  a  Verified Buyer  from  MD  on  May 23, 2017
    My old truck has needed new injectors for a few years, but the repair costs more than the vehicle. PI clears the check engine light and literally gets it firing on all cylinders again.
    Bottom Line
    Yes, I would recommend this to a friend.

    Works just fine
    By  Mr. HoneyDo,  a  Verified Buyer  from  Stafford, VA  on  April 30, 2017
    Not sure how well it worked as I put it in the wife's car. She didn't complain about anything so it at least didn't make anything worse. I really like AMS products and this is another quality item. Will purchase again.
    Bottom Line
    Yes, I would recommend this to a friend.

    Deep clean
    By  Eriction,  a  Verified Buyer  from  Phoenix AZ  on  February 10, 2017
    Smoothed out the idle and throttle response improved. I don't recommend using this all the time, but I think it is a must with every few oil changes.
