(6 pack) Berryman 2611 Intake Valve and Combustion Chamber Cleaner Kit for Gasoline Engines

Was having constant misfires in my 2016 Kia forte5 lx (GDI engine). I changed the spark plugs and injector coils multiple times and it still kept throwing codes. I even went as far as changing the fuel injectors and i was still getting misfires! I decided to try cleaning the intake valves as a last ditch effort before taking the car to a garage. This kit was very easy to use. Instructions were clear. You can use this by yourself, just hook everything up, push the button on the can and jump in your car and get those rpm's up to 2,000 until the can is empty. I drove the car 10mins as instructed and then let it sit for a couple of hours before driving it again. Took a 2 hour drive and NO MISFIRING!!!! I will never use anything except Berryman!

This is so much easier than other intake valve cleaners for GDI engines. It is well worth the money. The only complaint I would have would be to include in the directions to NOT tighten the throttle body boot too much because it pinches the line and the pressure of the spray pushes the can tube off the U shaped piece when it gets pinched. I immediately noticed a difference when I let it heat soak and then drove it. I smoked out my whole neighborhood and ran gently through the rough rpms until it cleared up and immediately had more pep. Some people experience an check engine code but I did not. I definitely recommend this product.
