Overview:

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 the 105 mm throttle body part number 112-581 or similar models. The base intake manifold is designed with a low height to aid the packaging of a plenum mounted air-to-water intercooler in a top-feed configuration. The 300-620 top-feed plenum entry configuration is designed to allow the included Hi-Ram 105 mm plenum top to be fitted to a low-profile base intake manifold. The short runner, low-profile base intake manifold intended for forced induction applications was conceived to package with an air to water plenum mounted intercooler with a shorter overall height than possible with other existing intake manifolds. The 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.

Features:

  • Designed for GM LS Gen III and IV engines equipped with GM LS1/2/6 (cathedral port) cylinder heads
  • Designed for forced induction (supercharged or turbocharged) engine applications with peak power at 7000-8000 rpm depending on the application. With forced-induction and the short runner length the engine rpm at which peak power occurs is more likely to
  • Modular design allowing the use of the included top-feed plenum entry

Cute!
I actually ordered these as mascots for a pb&j food bank drive at work. They're cute, well made, and a big hit with associates and customers alike. I do believe my dog would've loved them had I allowed him to play with them..

So cute
I have a 1.5 yr old cavapoo & cockapoo. They love the little squeaky toys that, esp my cockapoo. He likes to run around making them squeak. These ones are a little bit bigger than some of the others they have. I knew they would be. He still runs around with them, there’s just no squeaking. My husband loves peanut butter and jelly, I had to get them. They’re super cute! Made well.

I thought these are Cute My dogs didn't think so
These are cute and would work well for medium and larger dogs.  Not dogs under 25lbs.  The toys are to big for their little mouths and they can't get a hold of them to play with them.

Fun little ball!
Fun little ball! Glad I got the football version the regular ball would be a choking hazard for my Great Dane. The ball rolls and shakes on the floor which at first was scary, but now she loves it! She nudges it all over the floor to keep it moving, keeping her entertained for a bit.
