Runners are precision cast and ported to assure proper air flow

The Pro-Filer Spreadport HITMAN Series of intake manifolds have transformed the market forever. The HITMAN Series features a Tunnel Ram with your choice of dual or single carb top plate and the ULTIMATE Single Plane.

Each manifold is designed to take your power curve to higher levels without costly hand porting. They are truly revolutionary! Our tunnel ram design is lighter weight than most fabricated units and the solid cast design helps to reduce resonance, which effects high RPM horsepower.

The cast, pre-ported runners have been designed to eliminate airflow restriction and produce more power. The dimensional consistency is far better than fabrication. Also fits other brands of spread port heads (18°, 14°, 12°).

Available in 9.8 and 10.2 deck heights with either a single or dual carb top plate.
