Holley EFI Expands Lo-Ram Intake Manifold Lineup

The Holley LS1/2/6 Lo-Ram intake manifold kits are designed for GM LS Gen III and IV engines.

Holley has announced the expansion of their Holley EFI Lo-Ram intake manifold platform. They’ve released a huge assortment of upgrades, service parts and more. For starters, a new black-finish is available for both top-feed and front-feed LS1/2/6 applications. They’ve also released a 105mm snout upgrade for front-feed models (300-621) allowing customers to attach an LS 4-bolt 105mm throttle body. A re-designed throttle cable bracket is also available for this snout. Holley EFI engineers finished it all off by releasing a ton of service parts for customers wanting to mix-match their new lo-ram intake.

Lo-Ram Manifold Kit – LS1/2/6 Top-Feed (Black Finish)
The Holley LS1/2/6 Lo-Ram intake manifold kits are designed for GM LS Gen III and IV engines equipped with GM LS1/2/6 (cathedral port) cylinder heads. These intake manifolds will work with OE or aftermarket cylinder heads. The Lo-Ram intake manifolds are designed for forced induction (supercharged or turbocharged) engine applications and a 105mm throttle body (Part # 112-581). The base intake manifold is designed with a low height to aid in the packaging of a plenum mounted air-to-water intercooler for top-feed configurations.

105mm Throttle Body Adapter / Throttle Cable Bracket (Front-Feed)
The 105mm throttle body adapter allows the adaptation of a four-bolt LS 105mm throttle body onto a front-feed Lo-Ram intake manifold (300-621). The new snout is sealed with a 3/32 o-ring for a perfect boost-ready installation for your next power-added build.
Meanwhile, the optional throttle cable bracket is designed for 105mm throttle bodies and allows for throttle pedal adjustment as well as installation of a nitrous plate. It allows the use of factory 98-02 Camaro/Firebird throttle cables such as GM Part # 12563339.
NOTE: Throttle Cable Bracket is sold separately.

Lo-Ram Manifold Base & Rail Kits
The Holley LS1/2/6 Lo-Ram intake manifold kits are designed for GM LS Gen III and IV engines equipped with GM LS1/2/6 (cathedral port) cylinder heads. These intake manifold and rail kits will work with OE (Original Equipment) or aftermarket cylinder heads. Manifold bases are available for both top-feed and front-feed applications and allow for maximum customization when used with other available plenum tops. Bases are finished in either black or satin for customers looking to spice up their engine bay.
The front-feed manifold base can be used in conjunction with plenum top part # 300-604 and 105mm snout part # 300-606. These will aid in fabricating custom inlet configurations for power-adder combinations.

Fuel Rail Kits for Lo-Ram Manifolds
These replacement fuel rail kits are designed for the top-feed and front-feed Lo-Ram intake manifolds with a single injector per cylinder design. Finished in black anodizing, the high volume rails include the mounting hardware and have 3/4″-16 o-ring ports (8AN). Two sets of brackets are included, a set for long (usually standard length) fuel injectors and a set for short (like Pico or LS7) fuel injectors.
