Poor Air Intake

[BerlingoHDI]

Hi All,

i have recently noticed the air intake setup on the 2.0 hdi and to me it seems as though there isnt a way for cold air to be sucked in as the front grille blocks it, any way i have detached the the black plastic from the grille and it as opened up the intake for air to flow in.

i think it has made a slight difference especially in 3rd gear as it seems to rev more freely and a little bit higher, another thing is why is there slits in the intake pipe which seems to me as if it would suck warm air in and would any body recommend taping them up so that it just pulls in cold air from the grille.

Thanks for reading
Matt.
