Peugeot air filter
I have just serviced my Peugeot 308 renewing the pollen, oil, air and fuel filter but I have noticed that the car is louder than it was before. The air filter i took out was different to the new one which I have checked to make sure it is the correct one which it is.
This could be accounted for simply by the fact that the old air filter was dirty and therefore restricted the airflow into the engine, but the new air filter is clean. However, now that you have the old one out of the car, you can take it to a Peugeot dealer and compare it to the standard Peugeot replacement for the car.
