Rated 4 out of 5 by Lucas from It works but will need to be used regularly I bought a can of this Liqui-Moly Diesel intake decarb recently and used it on my 35,000km old diesel Audi SQ5. My intake manifold, intake pipes, and throttle plate already had a good 5-6mm of oily sticky mess stuck to the walls. I did find the Liqui-Moly product to be effective at breaking down the oily muck, but it did still require manual cleaning with brushes and towels etc to be properly clean. I will use this product on a regular basis from now on (eg twice a year) which i believe will make it more effective as simply a spray cleaner. If your car has 100,000km+ on it i doubt this spray on its own will do much.

Rated 5 out of 5 by Josh from Does as it says 2010 1KZ Hilux with 290k kms. I started the process by stripping off the top half of the intake setup and cleaning them conventionally. While they were off I was able to scoop as much as I could reach with a teaspoon out of the intake manifold and then reassemble. I now proceeded to use the intake cleaner knowing everything between the egr and the manifold was already spotless. I used two cans before I noticed the rev ups were not apparent anymore. After reinspection with a camera, I could see that the intake manifold had now indeed been cleaned of the buildup. I now notice quicker pickup, more power and no more smoke when you put the foot down. Thumbs up... great product.

Rated 5 out of 5 by Hilux 4x4 from A must have 4x4 Ok this product is a must for any diesel motor i have a 2013 toyota hilux sr5 its 90 thousands k's it had a slight tappet sound under load. A ryco crank case kit had just been fitted to help with the common problem off oil getting into the intake side so i decided to have tje throttle side all cleaned with the Liqui-Molly Diesel Engine intake Decarb I must say after it was cleaned i am amazed 1 it runs better motor is quieter 2 alot smoother under acceleration 3 no more tappet type noise So for anyone with a 4x4 or diesel car from my point off veiw you should use this product to stop all that carbon building up in your intake AAA+++

Rated 4 out of 5 by H.H. from good but not for clogged EGR i used one bottle before removing the manifold our of the car to assist the impact of the product on my EGR. after i removed the manifold i noticed no much difference on the clogged EGR valve, so i removed the solid residuals using high pressure water pump and cleaned the manifold out side the car and then return it back and did another round of decarb for the rest of the valves. i did notice a some improvement after the second decarb, but still i believe without removing the manifold it will not be possible to clean the EGR valve. this product can be used for regular preventative maintenance but not as a complete cleaner for the manifold. the conclusion, if you have a blocked or lot of carbon residuals, you need to clean it properly first then use this product every service to make sure things are running smoothly and you will not run into the same clogged issue later.
