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
  • 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
  • High volume fuel rails and mounting hardware included with ¾”-16 o-ring ports (8 AN)

Fun Toy for Active Dogs
My dog enjoyed playing with this toy and stayed entertained for a long time. It moves well and keeps pets curious and active. Easy to use and good quality for the price.

Durable Interactive Dog Toy with Bluetooth Sounds – Perfect for Dogs Who Love Cat-Style Toys
This interactive dog toy is surprisingly durable and very engaging, especially for dogs that love cat-style toys. My dog is obsessed with cat toys and also always wants to destroy something, so this toy is a perfect match. The Bluetooth sound feature makes it even more fun and interactive. Pros • Very durable main body made of hard plastic; my dog hasn’t been able to destroy it • Great for dogs that like “mouser-style” toys • Bluetooth feature lets you play animal sounds or music (I use Spotify dog playlists) • Three different modes and very easy to switch • Interactive and mentally stimulating • Comes with two replaceable ropes, which I’m really happy about Cons • The ropes don’t last long for strong chewers • The top part where the rope is attached can be chewed Overall Honestly, if there weren’t any parts my dog could destroy, he probably wouldn’t find the toy interesting. That’s why I’m actually happy it comes with two ropes that I can attach and replace. The ropes are inexpensive and easy to swap out, so it’s not really a downside for us. Overall, this is a fun and clever toy that keeps my dog entertained. 🐶

Great for 2 Days…see comments
So it’s great toy and had our dog entertained immediately. However probably won’t last very long with medium to large dogs that gets obsessed with killing every toy you give them. Our Pitt mix loved this until she ended it by chewing through the heavy plastic ring that keeps the ropes connected. Without the noted ropes attached, the toy cannot move around. Basically ending the fun. Would be great to start a puppy or smaller dog on. It has multiple modes and is noise and proximity activated. Our dog was obsessed but sadly it was no match for her. 3 stars only because it didn’t last more than two days with our dog.

Good but not tough
My dog loved it but he figured out how to open it pretty quickly. I think I’m doomed to never find an interactive dog toy that can survive my golden

Obsessed, crappy rope
My pitbull mix is obsessed! I was worried he might break it, but he has used it everyday for the past week and we've had no issues. The reason I docked a star is because the rope it comes with lasts minutes. I'm still trying to figure out a good solution of what to tie onto the top. Regardless, he loves it without anything on it, but he chews on the connector piece so I'm worried he will break it if I let him go.
