Do you have or want the CP-E alpha intake for the Ford Focus mk3 ST and RS? Do you want to ensure the airbox is only taking in air from the factory front feed?
Then you can upgrade the air box with this optional "Hermetic seal" kit from CP-E which adds 2 plexiglass plates to cover the gaps in the airbox, plus the hardware required to install them.
This fits all the CP-E Focus mk3 Intakes whether for ST, facelift ST or the RS
