Product Information

Holley LS Modular Lo-Ram EFI intake manifolds are designed for GM LS Gen III and IV engines equipped with GM LS1/LS2/LS6 (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 105 mm throttle or similar models. The base intake manifold is designed with a lower overall height to fit under a stock or mildly modified hood in the front-feed configuration. The modular design allows the use of front-feed plenum entry, while intake design facilitates custom inlet duct and throttle body placement.

Additional features and specs:

* Cast aluminum construction with satin silver finish
* Modular design allows the use of front-feed plenum entry
* Clears 4th Gen Camaro and C5 Corvette cowls and hoods without modification
* 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 being used
* High-volume fuel rails and mounting hardware included with 3/4 in.-16 O-ring ports (8 AN)
* Fuel rail kits include 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



  • Cylinder Head Configuration:Cathedral Port LS1/LS2/LS6
  • Fuel Injection Style:Multi-port
  • Intake Section Included:Complete
  • Throttle Body Bore Size:105mm
  • Engine Block Deck Height:Standard deck
  • Injectors Included:No
  • Multi-Port Fuel Rails Included:Yes
  • EGR:No
  • Aftermarket Fuel Rail Required:Yes
  • Throttle Body Included:No
  • Supplemental Bosses Cast-In:No
  • Supplemental Bosses Machined:No
  • Runners Included:Yes
  • Runners Removable:No
  • Plenum Material:Aluminum
  • Plenum Finish:Natural
  • Base Material:Aluminum
  • Base Color:Natural
  • Quantity:Sold individually.
  • Notes:Fuel rails are machined for -8 AN O-ring female fittings. Intake manifold features a plenum height of 5.17 in. and is designed for forced induction applications with peak power of 7,000 to 8,000 rpm.
