Nissan Skyline R33 GTS RB20E
Uprated High Flow, High Capacity Filter
If you are tuning your RB20E engine you need one of these high flow, high capacity Fuel Filters. Hesitation under acceleration can often be a blocked or inadequate fuel filter.
Cars running higher horsepower will benefit from the larger capacity reservoir of the fuel filter which means there is more fuel reserve to call on under wide open throttle conditions near maximum revs. This is the same reason to change to a larger capacity fuel rail, but this filter is an inexpensive and worthwhile alternative until you actually need one.The extra fuel capacity in the filter gives your fuel pump more time to provide extra fuel under severe acceleration- you can see the difference in size between the stock and the larger capacity filter in the second picture.
