Volvo S80 2.4T Trying Out An Open Cone Filter

I wanted to try an open filter, to hear the induction sound and the blowoff sound. I went with a big velocity stack type filter. Although it sounded nice, I already reverted it and went back to the original airbox.

Volvo S80 2.4T CAI Intake Modification

Decided to mod the intake flap to a more direct version, which should aid in forcing air into the airbox. Performance could be better, although right now I dont have the means to measure this.

VW Golf MK3 GTI Airbox Modification

The best airfilter on the Golf MK3 GTI platform is the original airbox with paper filter. But you might miss out on induction noise, something so desired on any naturally aspirated (NA) engine 🙂

There are ways to give you some induction noise, namely:

  • Drilling the airbox
  • Removing the snoot to the side of the car
  • Fitting a (Bonrath) Powerrohr / roar

I bought myself an extra airbox and removed the snoot + drilled extra holes on the cold side of the car.
