Not carb and choke cleaner! I used to use CRC GDI intake cleaner. Then I tried the expensive STP cleaner with the automatic timed dispenser. I decided to keep the dispenser and see if any other product cans fit. Low and behold... I found that the Lucas Deep Clean GDI cleaner fit on the dispenser while the CRC can did not. Then the Lucas started becoming hard to find and the price went up. I tried this Gumout foaming cleaner and the can actually fits the dispenser! Gave it a shot yesterday. I have rigged a means of connecting the tube to the brake booster hose with an air hose plug. I advise doing on a windy day as this stuff blows out a ton of white smoke that smells as you'd expect. Calm evening so the stuff lingered a bit. I became concerned neighbors would be alarmed. But the can dispensed fully in a shorter amount of time than other cleaners. It immediately set off some codes which I cleared and they haven't returned. I took a good vigorous drive after the treatment and codes never returned. Instructions don't say to turn off car and let sit... just says to idle car for 5 minutes then take a 15 mile drive. I've tried the Mopar foaming cleaner once and I see Amsoil has their Power Foam cleaner which is around $13 a can plus shipping which is probably about $8 under $100. So this Gumout stuff is a good deal and car is predictably more responsive and idles more smoothly, similar to other dedicated cleaners and seafoam I've used in the past. I do prefer the foam vs. liquid as I believe it may do a better job of contacting the surfaces that need cleaning.

Tried this product on my gdi engines to clean the intake valves had a misfire on cylinder one had to clean the spark plugs , didn't make a big difference .

Worked great in my 2018 Mazda CX3. I followed the instructions and went for a 15 miles drive afterwards. I did it outside on the street. The next morning I started the car and later noticed on the garage floor that there were 2 big black spots where carbon and condensation shot out of the exhaust pipes onto the floor. It was a lot. Also the car felt a lot more peppy and the throttle response was better.

I bought this for My 2018 Kia Soul with the 2.0 GDI engine. It has 340,000 miles and it idles a bit rough and I am assuming it's the intake valves being gunked up. I saw a guy on a video saying if your intake valves are really gunked up then they'll need a hand scraping or something like walnut blasting. I tried this STP cleaner anyways and it did not work for my car, how ever I believe these products are for low Mileage engine maintenance to prevent the carbon build up from getting really bad.
