Why Is It Important?
What Happens Without Timely Filter Replacement:
Air Filter
| Problem | Technical Consequences |
|---|---|
| Clogged filter | Engine “suffocates” → rich mixture → 5–15% higher fuel consumption |
| Damaged filter | Dust enters cylinders → abrasive wear → compression loss |
| Dirty MAF sensor | Incorrect airflow readings → unstable operation → Check Engine errors |
Fact: 1 gram of dust inside an engine can remove up to 0.1 mm of metal from friction surfaces.
Cabin Filter
| Problem | Technical Consequences |
|---|---|
| Clogged filter | Weak airflow → fogged windows → reduced visibility |
| Bacteria & mold | Allergies, coughing, headaches |
| Evaporator icing | Condensation blockage → ice formation → AC stops working |
Fuel Filter (Especially Diesel!)
| Problem | Technical Consequences |
|---|---|
| Water in filter | Injector corrosion → uneven spray → smoke & knocking |
| Clogged filter | Fuel pressure drop → power loss → engine stalls under load |
| Injector wear | Contaminants pass through → abrasive damage → injector set replacement 2000–6000 PLN |
Economics: a 50–100 PLN filter protects components worth 2000–10000 PLN.
Tips
- Replace filters according to schedule
- Carbon cabin filters are better for allergy sufferers
- Do not save money on diesel fuel filters
