Holley Sniper EFI Dual Plenum Intake Manifold 92mm Black (GM LS1/2/6) 820242

Holley continues to push the envelope of intake design with its latest offering. The unique look of this intake will surely stand out from the crowd!

Our latest release of fabricated "Dual Plenum" intake manifolds for GM LS1/2/6 and LS3/L92 engines. This unique design of utilizing two plenums solves two common problems experienced with many intakes increased airflow and even dispersion of air to intake ports.

The use of one tapered plenum to accommodate one bank of cylinders accomplishes both problems. The entire volume of incoming air is distributed to only four cylinders and the tapered shape of the plenum help increased air velocity directed to each of the intake runner ports.

Our dual plenum design features extremely long 12-3/4" runners to develop low-end torque making this intake an ideal "street" intake.

These intake are finished in our familiar silver and black anodized finishes for durability and good looks. Our 3/8" fuel rail kit include a laser engrave Sniper logo and are capable of supporting 750+ horsepower.
