Lately there have been just a few firms which have launched twin plenum consumption manifolds for LS engines. This design is nothing new, in truth the cross ram intakes of the Ramchargers Mopar days had been actual pioneers within the design, and a number of other Mopar manufacturing unit choices got here with an consumption that had related designs. Within the case of those new twin plenum intakes for LS Engines, every half of the engine is fed by a special plenum and runners, with their very own throttle physique and every part. The airflow potential is HUGE and which means large energy can be attainable. These new choices from Holley’s Sniper division positively have the wow issue coated, and so they make actual energy as effectively.
Right here’s all the data from Holley.
Holley/MSD is happy to announce the discharge of Sniper EFI Twin Plenum Consumption Manifolds.

It concurrently solves two issues frequent to lesser intakes: elevated airflow and even dispersion to all consumption ports.
100% TIG-welded, Sniper EFI Twin Plenum Consumption Manifolds are good for naturally aspirated setups and twin-turbo functions that must construct torque from low- to mid-range all the best way to 7,500 RPM and past. Their extraordinarily lengthy runners (12.75”) develop loads of low-end torque and, coupled with the twin plenums and throttle our bodies, enhance energy throughout all the RPM spectrum. They’re obtainable for each LS1/2/6 engines and LS3/L92s and are available your selection of a silver or black-anodized end and your selection of a 92mm or 102mm throttle-body opening.
