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 lower overall height to fit under a stock or mildly modified hood in the front-feed configuration. The 300-621 Lo-Ram front-feed plenum entry was configured to provide a very low profile modular intake manifold suitable for turbocharged or centrifugally supercharged engines. 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 be coupled to the supercharger or turbocharger being used
  • Modular design allowing the use of front-feed plenum entry
  • Intake design facilitates custom inlet duct and throttle body placement
  • Low height to fit under a stock or mildly modified hood in the front-feed configuration
  • Front entry plenum flange allows design & fabrication of special throttle body adapters or inlet ducts for custom installations
  • Clears 4th Gen Camaro and C5 Corvette cowls and hoods without modification
  • High volume fuel rails and mounting hardware included with ¾”-16 o-ring ports (8 AN)

Great toy for puppies!
Color: Turtle
I love this turtle. My toy poodle puppy has boundless energy. She loves this thing. It keeps her busy so I can get laundry and other things done. I am buying a second one for when the first one loses its charge😂

It broke within the week
Color: Turtle
The toy was ADORABLE, it worked very well for the first week. And then it broke. I bought two for my puppy and my 8 year old shih tzus. It stopped vibrating and just made loud grinding and squeaking noises. I would recommend this toy if it lasted longer.

Offers tons of activity
Color: Turtle
My 70lb dog LOVES this turtle toy, was worth the price. He will play and play until he’s exhausted. We have to give him breaks from it. We use the second setting which is just for movement, no music. The only aspect I don’t like is that he will inadvertently press the button when he’s biting the toy, changing the setting and sometimes has turned it off. The velcro is super strong, which is good but makes it difficult to open. Battery life is decent, lasted a few days with him playing with it an hour or so each evening. I like the auto shut off after 30 minutes of no movement.

Great toy for a dog who is not afraid of noises
Color: Crab
My puppy loves this thing! She was confused at first but now she plays with it daily. I just let it jump and sing the first time. She looked at it with the cutest head tilt. It is a bit loud so if you have a dog that's scared of noises this might be the right toy. Now when she picks it up, I turn it on and she gets so excited! The different songs make the toy less annoying for me, lol. Honestly, anything to tire out a 4 month old puppy. She is very entertaining to watch.

What a fun toy!!!
Color: Turtle
This is the first toy in a very long time my 10yo GSD wants to play with. She actually brings it over for me to turn on. It is loud and wiggly... She goes nuts for it! So far good quality with shaking and light chewing. Very easy to turn on and off. Great value for the play enjoyment of my sweet girl, gets her up and moving.
