Intake Manifolds

AN-8 6061-T6 aluminum hi-flow fuel rail extrusion for the fabrication of custom fuel injection systems. The 5/8" diameter fuel passage provides the flow capacity for high horsepower applications and the volume to dampen fuel pressure oscillations. The...

The Holley GM LS7 Modular Hi–Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet–metal for high–performance applications where induction system height is not limited. Coupling this Hi–Ram intake with the high flowing LS7...

The new Holley EFI Hi-Ram intake provides the ultimate performance with the new GM direct injected Gen V 6.2L LT1 engine. The modular design of this manifold allows easy disassembly for custom porting, multiple tops, or custom induction systems. Each...

EFI fuel rails are machined for –8AN O-ring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system.

1 x 105mm GM LT1 Throttle Valve Top Only. This part fits the GM Gen V LT1 Hi-Ram manifolds only (does not fit LS manifolds).

The Holley GM LS3/L92 Modular Hi-Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high...

Holley EFI is excited to launch four new multi-point fuel injection intake manifolds for the big block Chevy. These new intakes are available to fit oval or rectangular port heads, and 4150 or 4500 style throttle bodies. These Intakes are ideal for...
