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 manifold and rail kits will work with OE (Original Equipment) or aftermarket cylinder heads. The 300-624(satin) & 300-624BK(black) top-feed intake manifold kit provides two injectors per cylinder for hi-volume fuel demands, flexible fuel supply strategies, and dual-fuel capability. The top-feed, short runner, low-profile base intake manifold was conceived to package plenum mounted intercoolers for high-boost turbocharged or supercharged induction systems with a shorter overall height not possible with other existing intake manifolds. The plenum top is configured to be fitted with 105 mm throttle body part number 112-581 or similar models. The dual fuel injector 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. Available in satin and black finishes. Holley Lo-Ram intake manifold kits include all the sealing o-rings, plugs, and fasteners required for the installation of the kit.

Features:

  • Designed for GM LS Gen III and IV engines equipped with GM LS1/2/6 (cathedral port) cylinder heads
  • Provides best performance for forced induction (supercharged or turbocharged) engine applications with peak power at 7000-8000 rpm, depending on the application
  • Dual-injector, separate-passage, high-volume fuel rails with mounting hardware, dual-fuel capable, 8 AN o-ring ports
  • Low height to aid the packaging of a plenum mounted air-to-water intercooler in a top-feed configuration or to fit under a stock or mildly modified hood in the front-feed configuration
  • Available with both as-cast satin and black power-coat finishes

My dog's favorite toy
Not the best quality but my dog loves them so what choice do I have? The queaker breaks instantly. I have to buy one every couple months because they get kind of deformed after a while. Would be nice if they offered a discounted 3 pack.

Right size for medium size pet.
He loves it. It is soft and he has not tried to destroy it. Squeaks and just the right size. Medium size dog. Very satisfied with this purchase. He loves toys that squeak. Not too big and fits perfectly in his mouth.

Can’t live without it!
I always keep one on hand in case it gets lost. Very durable and sustains a lot of chewing. It is a constant companion and play toy (thrown in my face at 1:30 a.m. as a hint it’s play time). He sleeps with it. Puts it by his bowls as he eats and drinks. Take outside for walks and play. Greets me when I come home with it. Greets guests with it. Has MANY other toys he will enjoy but nothing like a pacifier! He’s had one for years (he’s 9). One baby I’ll never take it away from. And since he’s a Shih Tzu- don’t think I have to worry about orthodontia. Highly recommend give it a try - despite mixed reviews - all dogs are not alike.

Last thru our entire teething stage
I absolutely love this. I got this when I first got my puppy (miniature dachshund) for when she started teething. It lasted her entire teething stage and she chewed on it everyday. If her teeth were really bothering her I shoved it in the freezer like the baby teething rings for about an hour and then gave it to her. There's only a few parts where her teeth cut it but it wasn't anything major or concerning. I definitely recommend for smaller breed dogs. It's somewhat smaller so I don't think it would be to great for bigger dogs.
