A picture familiar to many "would-be motorists" - trying to save money on consumables while going through MOT, they do the following. Instead of buying a new engine air filter , they simply shake out the dust and install the old one in its regular place. The incorrectness of such "care" can be explained by the following reasons:
- The filter does not belong to the category of expensive consumables and you should not save on it.
- You will definitely not be able to clean the "honeycomb" of the old filter from stubborn dust and dirt.
Bottom line, poor air flow and the ingress of contaminants into the combustion chamber. Consequences, unnecessary fuel consumption (this is what you need to save on) and serious engine repairs in the very near future.
Buy original
It will be much cheaper to buy an original air filter for your car engine (if you compare prices with a dealership) from a direct supplier of this type of components. As a rule, you can find it via the Internet by creating a corresponding request in the browser's search engine.
