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.
