Holley LS Modular Ultra Lo-Ram EFI Intake Manifolds

Holley modular Ultra Lo-Ram intake manifold kits feature a design custom-made for LS engines equipped with LS cathedral port cylinder heads, as well as OEM or aftermarket models. They provide an ideal solution for forced-induction (supercharged or turbocharged) engine applications and select throttle bodies—plus the base intake manifold features a lower overall height to fit under a stock or mildly modified hood. The included fuel rail kits come with two sets of brackets: a set for long (usually standard length) fuel injectors and a set for short (such as Pico or LS7) fuel injectors. The Holley LS modular Ultra Lo-Ram EFI intake manifolds best suited for your application also allow the use of front-feed plenum entry.

More product features, items, and notes include:

* Designed for forced-induction engine applications with peak power at 7,000 to 8,000 rpm (depending on the application)
* Intake design facilitates custom inlet duct and throttle body placement
* Allows design and fabrication of special throttle body adapters or inlet ducts for custom installations
* Different finishes available for the best look to match your ride
* Mounting hardware
* With forced induction and the short runner length, the engine rpm at which peak power occurs is more likely to be coupled to the supercharger or turbocharger you use
