JLM Petrol EGR & Air Intake Cleaner

JLM Petrol Air Intake & EGR Cleaner has been specially developed for cleaning the soot accumulation and other deposits in the exhaust gas recirculation system (EGR).

  • Quickly cleans exhaust gas recirculation system (EGR)
  • Dissolves rust, dirt and (soot) deposits
  • Optimizes the air supply to the engine
  • Improves power and acceleration
  • Reduces smoke from the exhaust
  • Stops irregular idling
  • Prevents the engine from stopping

Combustion engines must meet increasingly stringent environmental requirements and emit less harmful exhaust gases, such as nitrogen oxides (NOx). One of the solutions to reduce the emission of harmful gasses is by using Exhaust Gas Recirculation (EGR).

  1. EGR works by capturing dirty exhaust gasses and redirected them to the combustion chambers in the engine.
  2. These damaging gasses are mixed in the engine with fresh intake air. As a result, the quantity of oxygen in the intake air decreases and the combustion chamber is filled with gas, which does not undergo a chemical reaction.
  3. The heat generated during combustion has to be dissipated over a greater mass and consequently the combustion temperature drops.
  4. NOx occurs in particular at high combustion temperatures, but, because the combustion temperature drops through the application of EGR, the quantity of NOx also drops.
  5. Nonetheless, a drop in NOx means the chemical reaction causes soot. This is where EGR cleaners come in.

Continue operating a safer, cleaner engine with JLM Petrol Air Intake Cleaner & EGR Cleaner. It removes the harmful soot, allowing your EGR to work at full capacity. Stop your engine from deteriorating and avoid pistol rings and oil scraper rings from seizing up. If they do, the seal on the cylinder will be less effective and your engine will heavily consume oil.


Follow this guide for a safer, cleaner air intake and EGR:

  1. First, warm the engine.
  2. Second, remove the flexible hose in the air intake system.

    1. Find the air intake system between the turbocharger/intercooler and the air intake manifold (this cleans the air intake manifold and inlet valves).
    2. Or, locate it before the turbocharger (this cleans the air intake system before the turbocharger).
    3. Or, find it before EGR valve (cleaning EGR valve), depending on which part you want to clean.

  3. Please note, it’s important that you:

    1. Do not spray directly through the intercooler.
    2. Remember that when applying JLM Air Intake & EGR Cleaner the engine rpm can increase or decrease and diesel knocking may occur. This is due to the addition of liquid, and the change in the air/fuel ratio.

  4. Start the engine, and let run at idle.
  5. Spray the product in short intervals of 1 to 2 seconds into the air intake manifold. After each pulverisation the engine rpm may increase or decrease; wait for engine rpm to stabilise before spraying again.
  6. If during application the engine rpm decreases, accelerate a little to avoid stalling of the engine (up to approximately 2000rpm)
  7. If the engine rpm increases during application or diesel knocking occurs, leave the engine idle during application. Do not accelerate!
  8. On some vehicles, the application is easier with the use of the additional extension tube.
  9. Continue until half of the product in the aerosol is consumed.
  10. Let the engine run at idle for 2 minutes

  11. Stop engine and re-connect air intake hose.
  12. Start the engine and accelerate the engine approximately 5 to 10 times; do not exceed 2500rpm, or drive for 3 to 5 miles to help the release of all the carbon in the system.
  13. Allow the engine to idle again for at least one minute before stopping the engine.


These instructions will help you to carry out a thorough EGR cleaning procedure. However, if you have any doubts, we advise you to stop using JLM Air Intake Cleaner and ask us or a professional car mechanic for advice.
