Hallo,
Going to be fitting maniflow manifold without a K&N Induction kit (funds!! & the original exhaust has a hole before the CAT so had to be replaced)
The standard air filter box will be retained but has a K&N air filter element inside.
Seeing as you cannot fit the original hot air box to the new manifold (I presume) should I leave the hot air intake flap as is or just remove the vacuum tube and plug it like you would with a K&N air induction kit??
Anybody had experience??
Thanks
