How to Clean Cold Air Intake Filter

An automobile air filter’s job is to let clean air into your engine, where it may mix with atomized fuel to generate power. The dust, grime, and other airborne particles clog up your air filter as it is utilized. In order to preserve vehicle performance and MPG, you’ll need to replace or clean your air filter when this occurs. Continue reading to learn how to clean your unclean automotive air filter and restore your vehicle’s ability to breathe.

Filters (oil vs. dry)

The most noticeable distinction between the two kinds of air filters is that one is oil-coated and the other is not. This relates to the cleaning process: owing to re-oiling, oiled air filters need an additional step. Oiled air filters are made up of multiple loose layers coated with sticky oil to trap particles and optimize airflow. Dry filters clog more quickly than oiled filters, but they’re also easier to clean. If your air filter is oil-coated, don’t use soap and water on it.

Tools Required

• Bucket

• Cloths with microfiber

• Screwdriver

• Vacuum

Materials Required

• Dishwasher liquid

• Water should be warm.

  • Air Filter must be removed
  • Vacuum the Air Filter.  Shake off bigger bits of material by tapping the air filter several times.
  • Wash the Filter

• Gently swish the water-filled air filter.

• Run warm water over the air filter to completely clean it.

• Shake extra water out of the air filter by tapping it.

• Make sure the air filter is totally dry by laying it flat in the sun. Before replacing, make sure the air filter is totally dry.

Symptoms of a Failing or Bad Cold Air Intake System

If you witness or feel loss of power and acceleration it means there is something wrong. Fuel economy and high idle which is not normal plus the light of check engine that keeps going on are also major signs of bad cold air. Because cold air is substantially denser than hot air, it is more conducive to engine induction. As a consequence, the engine will be capable of producing greater power. A issue with the cold air intake usually manifests itself in a few symptoms that warn the driver to a possible problem that should be addressed.

1. Reduction in engine performance

An engine air filter is also used in the cold air intake, which may reduce power, acceleration, and fuel economy if it becomes clogged or unclean. A clogged air filter might also make it difficult to start the car in more severe circumstances.

2. Excessively high or surging idle

An unusually high idle is another sign of a possible issue with the cold air intake system. A high idle speed might signal a vacuum leak.

3. Check Engine Light comes on

The Check Engine Light may illuminate if any of the sensors placed in the intake detect any faults, alerting the driver to a concern. The Check Engine Light may be triggered by a variety of issues, including vacuum leaks and defective sensors.  It’s an important component of the formula for achieving the desired pedal-induced pleasure. Air, on the other hand, is not formed in the same way. In terms of combustion, the quantity of oxygen in air is crucial. More fuel may be burnt when the air contains more oxygen (which can be supplied through a nitrous system). However, without using nitrous, you may enhance the quantity of oxygen in the air that enters the intake.

The Benefits and Disabilities


 It is not only located outside of the engine chamber, but also at a low elevation. This is a two-pronged advantage. For starters, since heat raises, hot air from the engine compartment, brakes, or any other heated component is avoided. Furthermore, since colder air is denser and denser air is less dense, this filter is positioned to draw the densest air possible. The more gasoline that can be burnt and the more power that can be created for improved engine performance, the denser the air becomes.


The cold air inlet gets denser air than the standard one. It is, however, often more costly since it is longer and requires more complicated routing. As a result of the increasing complexity, installation becomes more complicated and time consuming. The cold air intake system’s most advantageous feature might also be its most dangerous flaw. It’s because of the filter’s placement, to be more exact. For colder, denser air, a low-placed filter outside the engine compartment is ideal. It doesn’t matter how healthy your diet is if you drink a lot of water. Your car’s engine might hydrolock if it ingests a substantial volume of water.

Will a cold air intake increase the noise level in my vehicle?

Yes. A cold air intake will make your vehicle’s sound louder and more forceful. A cold air intake, on the other hand, alters the sound of your vehicle’s engine rather than making it louder. This is a highly gratifying sound that makes your automobile sound even more aggressive and speedy. While it is advised that you replace your car filters on a regular basis, cleaning certain filters may help them last longer. However, since cleaning filters becomes less and less efficient with time, all filters must eventually be replaced. It’s best to get them changed by a mechanic at this stage.

Will my engine be harmed by a cold air intake?

The simple answer is “yes.” You may lessen the possibility of these concerns by installing, caring for, and maintaining your equipment properly. Knowing the warning symptoms of an issue can also allow you to intervene before more severe harm is done.

Is it possible to get Hydrolock from cold air intakes?

Without splash shields and fender lines, driving with a coil-air intake will create complications. A cold-air vehicle is probably not for you if you can’t avoid driving through water that is more than 6-8 inches deep.
