With a max overall height of only 10.44\", the Mid-Rise manifold is an excellent choice for street and performance street\/strip applications with a powerband from 1,500-6,500 RPM and limited hood clearance.  It's perfect for a blow-thru or turbocharged application.\nBeing part of the Holley modular intake line means that this intake is not only available as a complete kit with intake, adapter, 92MM top and fuel rails, but all parts can also be purchased separately for a custom intake build. The plenum adapter (PN 300-267) will accept all of the popular Holley Hi-Ram plenum tops as a foundation for custom induction systems.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures and Benefits\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e• Provides great performance to 6500 rpm for street\/strip performance applications while providing the look of a racing EFI intake manifold\u003cbr\u003e• Unique modular design allows the combination of a traditional dual-plane layout with an EFI manifold plenum to produce great mid-range torque without compromising top end power\u003cbr\u003e• Great for supercharged or turbocharged engines\u003cbr\u003e• Power band from 1500-6500 rpm\u003cbr\u003e• May require an aftermarket hood for some vehicle applications.\u003cbr\u003e• Cast aluminum construction\u003cbr\u003e• Intended for use on all GM LS Gen III or IV engines equipped with LS1\/LS2\/LS6 style cathedral port cylinder heads (recalibration of the ECU may be required when using this intake manifold design with OE ECU).\u003cbr\u003e\u003cbr\u003e\u003cem\u003eHolley EFI LS main harnesses have a map sensor connecter designed for use with an LS1\/2 style map sensor.
