Have a K&N induction kit on my MY98 uk scooby at the moment but getting to the stage where I am getting tired of the noise, I have a high flow panel filter sitting in the shed but have been hesitant to fit it as I am not sure what degree of power loss there will be putting the std airbox back in with a panel filter over the induction kit.

Mods are VF28 turbo

full HKS downpipe / hiper system

Boost controller running 1 bar 1.2 for fun mode

got standard filter box with green filter running 300+ bhp no problem and no noise. believe standard air box is good upto 350 bhp.

The O.E. air box with a K+N pannel filter has a lot going for it. It will not be a restriction on your set up.

 

Thanks harvey,

off to the shed to dig out the o.e airbox it is then
