5.0 out of 5 stars I'm a mechanic, works great!
Tried this in a 1.6 Hyundai Gamma II GDI engine that they put in the Kia Soul's. (Yes, Hyundai makes a lot of Kia's parts, including that engine). The proper way to clean intake valves on a GDI (direct injection) engine is to REMOVE the intake manifold and walnut-blast the back side of the intake valves. BIG JOB, and not always necessary. I inspected the intake valves with a borescope BEFORE and AFTER I used this product. It cleaned the intake valves very well! I've long used CRC products, and this will be another one I recommend every oil change, because, why NOT! Keep those valves as clean as you can, it will improve gas mileage and prolong the life of your engine. It will prevent carbon build up. NOTE: If your intake valves are too dirty, you will need to remove the intake manifold and clean the proper way. But this product works well, especially if you have a new car and begin using it right away at least every 10,000 miles, or every 2-3 oil changes. On the Kia Soul, I removed the brake booster vacuum line and sprayed the CRC direct injection intake valve cleaner into the system that way. SECOND NOTE: DO NOT SPRAY CRC INTAKE VALVE CLEANER IN THE AIR CLEANER/FILTER BOX, IT WILL DESTROY YOUR MAF (MASS AIR FLOW) SENSOR.
5.0 out of 5 stars It works very well on Hyundai GDI.
Read the instructions well! Understand what you need to do.I used this multiple times and it works well. Price is creeping up but I needed a bunch, Bolo was cheaper then autozone.
5.0 out of 5 stars Helps!
I used this this weekend on my 2001 car with 65,000 miles on it, it also has a mpi type of injection instead of the gdi as it is commonly used on. The car did not smoke white once during it's use spraying the production in as some have mentioned but it did idle rough as soon as I disconnected the air intake hose from the throttle body. I don't think the spray itself made the car idle any worse. But when the spraying was done, removed it and reconnected air intake hose and it immediately idled smoothly again and then I shut it off and let it sit for the time required. After that time I took it for a drive which was still smooth, but after a while of driving the check light flashed a few times off and on and then went out. Sometime thereafter the big cloud of white smoke came out of the exhaust and then nothing else out of the normal. Now today, a day later I noticed the car is idling as smooth as it did when it was new and also is very hard to hear running it is so smooth and starting is better too. I have to guess that it did work. It has increased take offs and overall power so I suspect it will affect the gas mileage too, when I check that.Thank you.
4.0 out of 5 stars Works fine on 2006 Lexus IS250 (no engine damage detected per oil analysis)
I did two successive treatments at about 1,000 miles apart, then I changed the oil. Just before I changed the oil, I sent an oil sample to Blackstone Labs for analysis. No engine damage was detected in the analysis (see report in photo).I'm docking one star off this product because it's a bit scary to use. The first time I used it: the engine knocked, pinged, misfired, and the check engine light came on during the test drive. The light turned itself off after a few restarts and 50 miles of driving. The second time I used the product, when the engine knocked, pinged, and misfired, I pulled over to the side of the road, put the car in park (or neutral), and revved the engine a few times (not exceeding 3,500 rpm per instruction). This cleared out the excess (lots of smoke came out the tailpipe) and I did not get a check engine light.To keep the engine at 2,000 rpm while spraying, I built a rig using Reach 'n Spray and some bicycle brake parts (see photo). That way I can spray and sit in the driver's seat. Originally, I used a fuel line to extend the straw to the vacuum port (see photo), but the Technical Support Staff at CRC advised me to spray directly else the solution may not atomize properly which may lead to engine or catalytic converter damage.Here's the instruction:1. Warm up the engine2. Spray in 1-second bursts and 1-second rests while keeping RPM at 2,000 until can is empty3. Rev engine 3 times not exceeding 3,500 RPM, then idle for 1 minute4. Shut engine off and wait 1 hour5. Start engine, rev engine a few times not exceeding 3,500 RPM to clear out excess, and drive at highway speed for at least 10 minutes. (If the engine runs rough, pull to the side of the road, put the transmission in park or neutral, and rev engine a few times (do not exceed 3,500 rpm per instruction) until no more smoke comes out of tailpipe, then continue driving at highway speed.) If your engine continues to run rough, repeat the above procedure to clear out the excess solution. Do not put a heavy load on your engine or drive at highway speed until the knocks, pings, and misfires are gone (you may damage your engine).I sprayed through a vacuum port closest to the throttle body. By spraying through that vacuum port, I keep the spray atomized and avoid accidentally spraying the MAF sensor. Do not spray the MAF sensor as this could trigger a check engine light or damage the MAF.Here's my understanding: CRC GDI IVD Cleaner uses polyether amine (PEA) as detergent. This detergent needs a heat soak to help emulsify with the carbon. Then when heated the emulsion vaporizes and goes into the cylinder and out the exhaust. The cleaning process is slow: if you have 100,000 miles on your engine the average amount of carbon removed from your valve is about 10-20%.I plan to do this cleaning procedure before every oil change.NOTE Lexus IS250: For better distribution of cleaning solution to all cylinders, use the EVAP port or the PCV port on the air surge tank (upper intake manifold) to shoot in your cleaner (see Photo with ports labeled). The Toyota ACIS (Acoustic Control Induction System) divides the air intake into upper and lower paths. You want to shoot the cleaning solution before the divide. Only the EVAP and PCV ports are before the divide. All other ports connect to the upper path, so the lower path is not cleaned. When spraying into the EVAP port, temporarily use a 5/16 inch diameter hose to bridge from the EVAP VSV to the UNUSED vacuum port (see photo).WARNING: You can damage the engine if it hydrolocks. Be sure to maintain 2,000 RPM and spray in short bursts. For added safety, you can rev the engine 2-3 times every 30 to 45 seconds to prevent puddling of the cleaning solution in the intake tract. The EVAP (PURGE) or PCV ports are the recommended ports to use (other ports may not distribute the solution properly causing engine or catalytic converter damage).
5.0 out of 5 stars Works great on GDI motors
Works great, improves gas mileage, easy to use. Pays for it self over time.
5.0 out of 5 stars Be sure you have a code scanner tool to clear the check engine light
I've used this several times and it does seem to clear out the carbon. It will almost certainly cause the check engine light to come on due to misfires and other codes. If you don't have a code tool to clear those it might make the car go into limp mode and only go maybe 20 MPH. If you can clear the codes this is a good product for direct injection engines. If you can't clear the codes you might consider not using this.
5.0 out of 5 stars smoother, more MPG
made engine smoother and gave more MPG. I was very nervous at first because every warning light came on after treatment and ran very rough. It eventually smoothed out with great results.This actually fixed my issue on the VTC actuator rattle on a Honda engine. did not expect that
5.0 out of 5 stars Super strong cleaner.
This product effectively cleansed my engine, delivering exceptional results. I highly recommend it to my associates and acquaintances. Its superior quality is truly commendable.
Para cualquier motor de Inyección Directa. Gasolina o Diesel
Siguiendo las instrucciones es muy fácil de usar. Asegúrate de aplicarlo por la succión correcta de tu motor, si tienes dudas busca en youtube como hacerlo para tu vehículo en especifico.Lo use hace años en una Mitsubishi L200 2.5 Turbo Diesel, cuando esta tenia 120 mil kilómetros, use dos botes ya que nunca había tenido una limpieza de válvulas y rejuveneció el motor.Y lo acabo de usar en un Subaru 2.0 no turbo con 23 mil kilómetros en el odómetro, y aun con tan pocos kilómetros el resultado de la limpieza de válvulas fue notable. Pienso seguirlo usando cada 20 o 25 mil kilómetros.Si no lo encuentras busca otro producto similar que contenga PEA (Polieteramina) y úsalo de similar manera
It works! But scary!
Tried it this morning and to be honest it was kinda scary to use. As you know any foreign chemical inside the cylinder can and will break your engine.My Kia Rondo was suffering from carbon buildup and I was losing a lot of mileage and power during acceleration. Emptied a whole can of it and waited for 1 hour to heatsoak the carbon. So me and the wifey drove around the block then there it was the big puff of white smoke came out of the tailpipe.I thought well its ok as what the reviewers say but the valve knock and the loss of power scared the heck out of me.I actually smokescreened an entire block around our area and people were looking at me saying that my engine is toast. I was quiet and trying to gather my thoughts on what happened as I looked on the dash and the it threw a CEL which I told my wife about it.we were silent and thinking. Me about the car whereas my wife calculating how much we will spend on a whole engine! XD. I pulled over and revved the engine just to remove the smoke and after that I did some spirited driving in one of our main roads and there was a change in acceleration and the car had power on all gears now. It even did a 5 gear uphill which was impossible to do when you have carbon build up. Gas mileage was unbelievable. I got another liter off my range. it used to be 10l/100km now it became 9km/100km city driving. Also about the CEL it went gone after 50 to 80 km of driving.Final Verdict. 10 out of 10 for how the cleaner worked but if you are scared to do it, I suggest ask a professional mechanic to help you. I still have 1 can left and I will use it after a few years but will take apart the plenum chamber to do a thorough clean. I will not spray it again while the engine is running.

المنتج مفيد لتنظيف الصمامات ( البلوف ) وايضا تنظيف المحركات بنظام gdi والمنتج يعتبر اقوى ب 150 مرة من منظفات الوقود العادية ، انصح باستخدامه
It's ok
Maybe problem with my car, I wasn't able to get it past the throttle body to spray past the maf sensor.I used it, didn't notice a difference tbh. Maybe I should have done it through the vaccum line
awesome
does what it needs to do very successfully
