Hiff 44 Stub Stack
Hiff 44 Stub Stack
The MED aluminium stub stacks have been extensively tested on our 110 Superflow flow bench to optimise the elliptical radius on the stub stack. The result is improved air flow to the carburettor and a proven increase in performance – on a wide range of different engines and rolling roads.
Combined with the genuine ITG air filter, this offers an unbeatable package for the single HIF44 1.75-inch SU carburettor. The filter base plate is laser cut from lightweight aluminium, while the specially-designed ITG filter with full radius sides gives an easy fit within the standard bulkhead.
Whereas many aftermarket air filters have a solid plate opposite the carb mouth, the ITG design offers maximum airflow through an open-style foam filter.
On a 1293cc Road Competition engine with the MED HT camshaft, the HIF44 Stub Stack System gave an extra 4.2bhp @ 5800 RPM over a cone filter.
