Description

The LS3 Ultra Lo-Ram intake manifold offers versatility with options for single or dual injector provisions and a burst panel flange, catering to boosted combinations while ensuring hood clearance.

Engineered for GM LS Gen III and IV engines equipped with LS3/L92 cylinder heads, these intake manifolds are compatible with both OE and aftermarket cylinder heads. Tailored for forced induction (supercharged or turbocharged) engine applications, the Ultra Lo-Ram is optimized for peak power at 7000-8000 rpm, application-dependent. The plenum flange boasts a 105mm opening, accommodating throttle body part number 112-581 or similar models.

The base intake manifold features a lower overall height, facilitating a fit under a stock or mildly modified hood in the front configuration. The LS3 Ultra Lo-Ram is specifically designed to provide a very low profile modular intake manifold, making it suitable for fabricating special throttle body adapters or inlet ducts for custom installations. Options include single or dual injector provisions and a burst panel flange.

Fuel rail kits include two sets of brackets for long (usually standard length) and short (such as Pico or LS7) fuel injectors. Additional features include:

Front entry plenum flange allowing design and fabrication of special throttle body adapters or inlet ducts for custom installations
Clearance for C6 Corvette cowls and hoods without modification
High volume fuel rails suitable for eight and sixteen injector configurations
Mounting hardware included with 3/4-16 O-ring ports (8 AN)
Billet options for the top and throttle body adapters are available separately.
