I have a nissan d21 with the Z20 engine with stock carb
Im looking for a performance air filter that will completely replace the stock air box anyone know anyone selling one? Or where to get one and what fits
Just fit the stock airbox from a car that had a bigger engine, like a falcodore or patrocruiser. They will be cheap, have a larger filter area (which is where the lower pressure drop comes from), but will still have a realistic level of filtration, unlike a pod filter.
