Hey @Desi Gt86,

Welcome to the forums

We have noticed a very slight bump in airflow when using an AFE and K&N drop-in filter.

Remember that the results you see for tests done internationally will probably show a higher hp/kw gained then what we should experience here on our fuel assuming the tests were done on the required octane for the 86 there and 95 Pump fuel here, however it still gives you an idea as to which flows better.

Due to the extra airflow from a drop-in filter, it will cause the car to run a little leaner which will usually result in more power, however a leaner car is more octane dependent for pre-detonation prevention.

As @FT_86_SM_GP said, the K&N will be your best bang for buck. We have found its airflow increase to be similar to that of a AFE filter.

Another advantage, and probably he biggest, is that drop-in filters are usually washable. This means that instead of waiting 30000-45000km (which is far to long for our local conditions IMO) for your filter to be replaced by the dealer, you can wash your filter say every 10000km and simply swap back to stock when its time for a service.
