Great for gdi engine especially my 2019 accord. Way cheaper

I I have a 1931 Model A Ford that was running poorly. I put a bottle of this through and it made quite a bit of difference.

2013 VW GTI kept setting off the P0304 code - misfire on cylinder 4. Changed plugs and coils - kept on getting the same light. Tried this stuff before I replaced injectors and guess what? No more lights. Worth trying if you are having misfires. May not be the solution but it's a good, cheap way to start finding the cause.

After walnut blasting intake valves about 6 years ago, and installing an air/oil separator I've used this product at least once every year and so far has maintained gunk away. No rough idle problems nor check engine codes. Always pumped after MAF before the turbo inlet. This is a must have for GDI vehicles.

I have a GDI Accord with the 2litre turbo. It's at 44k miles and there's no hiccups yet, but I know these engines will always carbon up if you don't get an methanated water injector installed in the intake manifold. I had my garage administer this before and oil change and my car feels smoother that I ever remembered. I also run Redline oil which has high phosphorous and magnesium, but jeez louise this stuff works wonders.

Works great and easy to use. Helps keep my car running smooth.

If you feel comfortable doing so, follow the professional instructions and add the fluid through a vacuum line (I used the brake booster). Make sure to use short bursts-let the engine rpm come back up before spraying again-you don't want too much liquid in the intake.

Worked like no other! It really broke up the build up and engine feels like has little more power

Mini Coopers are notorious for high carbon buildup due to their GDI engines. This isn't a replacement for a walnut blast which is the best way to clean the buildup, but at a range of $400-$800 to have one done, using the CRC GDI IVD Intake Valve Turbo Cleaner helps delay the inevitable. I have a 2012 Mini Countryman S All 4 and I loosen up the hose clamp and slide the straw under the hose, just past the Mass Airflow Sensor as shown in my picture, keeping the hose full connected. This allows the spray to flow through the turbo first, then into the intake valves cleaning both the turbo and the intake valves. This works so much better if there is second person who can keep the car idling between 2000 and 3000 rpms while spraying. Without the second person, I placed a brick on the peddle to keep the idle around 2500 rpms during the process. It takes about 20-25 minutes of spraying in short bursts, so you don't stall the engine. After emptying the can, shutting off the engine and letting it hot soak for a couple of hours, I'll take it on the interstate to blow it out, the engine felt smoother, yet I never got the smoke show of carbon getting blown out the exhaust like you'll see with seafoam. I found out the smoke show is hit or miss with CRC, yet it doesn't mean that it's not working if you don't get the show. I know this won't clean the intakes fully, yet it helps keep my car running smoother until I'm ready to commit the money to the full cleaning. There are plenty of videos on YouTube that will show you how to use the cleaner.

2012 kia soul GDI. engine valves were making loud noise. i thought is was the end of the engine. removed the air intake while engine was warm. sprayed and watched carbon disappear. ran much better. pulled the injectors and one was clogged. used to clean injector tip. CRC GDI IVD Intake Valve Turbo Cleaner.

Used this on a Hyundai Veloster with 98,000 miles on it. Completely fixed an rattle I'd been having at high RPM in high gears.It's very difficult (almost imppssibpe) to use with just one person, because the engine needs to kept running at 2000RPM while spraying, and spraying it makes the engine want to stall.But with one person spraying and another on the gas pedal, it only took about 10 minutes to fully empty the can into the air intake. After waiting the requisite hour (was really more like 2) I started the car and took it for a drive.When I hit about 40mph, there was a series or ominous sounding noises, a plume of nasty white smoke, and then the engine was running better than it ever has in the time I've owned the car.So, a little bit scary to use but seems to have worked great.

I was skeptical but decided to try this in my 2015 Kia Forte5 1.6l turbo GDI. I followed the instructions to the letter, inserting the product through the intake while my wife assisted holding the car at 2K RPMs. Waited the hour and the I could definitely feel the engine respond much better. Gas mileage and the idle seems to be better as well. I will use this every 10K miles as indicated.

I have a 2013 mazda3 and it hasn't been cleaned probably for 75k miles. After following instructions and cleaning intake, I started my car and went to go drive at highway speeds for 10 minutes. After the first bellow of smoke I immediately had lost most engine power, my check engine came on and was blinking, my DSC light tuned on, and I was running rich and has a misfire in cylinder 4. After getting it home and attempting another drive, after the second bellow of smoke, same thing happened. Went home, cleared codes, and went out for a third drive. Third time was fine. Car is back to normal, no codes, and runs better imo. Throttle seems to be more responsive or so. I'll be buying this often!

Very good

This stuff works great! I was getting a P050D error on my Autel after my check engine light came on. Code was for Cold Start Rough Idle and is caused by cylinders misfiring. The expensive solve is a replacement of spark plugs and fuel injectors, but I figured I'd give this a try, along with a bottle of Tecron in my gas tank.I followed the directions which were pretty easy, and a couple days later my check engine light went off!So glad I didn't have to go the route of replacing the fuel injectors! Will be using this stuff every 50K miles or so from now on!

It was easy to use. Just remember to do an oil change after using.

If you own a Car with GDI / Direct Injection, This stuff actually works and will be something I do, every time I change my oil.

Buen producto

Wow. Just plain wow.
