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.
