Intake Leak After Air Filter Change: Causes
Key Takeaway
Changed the air filter and now have codes? You probably created an intake leak.
Why Air Filter Changes Cause Intake Leaks
| Mistake | Result |
|---|---|
| Airbox clips not latched | Unmetered air enters |
| Filter seated incorrectly | Gap in airbox seal |
| Intake tube popped off MAF | Massive unmetered air |
| MAF connector bumped loose | Sensor can't read airflow |
| Cracked airbox (forced open) | Permanent air leak |
Fix
1. Open the airbox and re-seat the filter.
2. Ensure ALL clips are latched tightly.
3. Check the intake tube between the airbox and throttle body.
4. Verify the MAF sensor connector is plugged in.
5. Clear codes and test drive.
