Cold air intake lead to loss power going uphill

[Faboy]

Hi. I have the Ford Focus MK2 Duratec 2.0. When i installed the K&N cold air intake kits, everything was fine until i was going uphill. I can feel that the car was losing power ( vs the stock intake ). What do i have to do to solve this issue. 

Thanks guys

Rip it off, it's pointless, spend the money on changing the OEM paper filter every 10k.

Did you reset the ECU after installing it?

How to reset the ECU btw

Remove the negative battery lead for about 30-45 mins then the ECU will relearn and adjust for any changes.

You need a good cold air feed as it will back off the power as it heats up I had a ramair and in the winter it's great in the summer I switched back to the stock air box
