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)

Very nice if you aren't too pick on actual color.
Size: Single Pelt/2 ft x 3 ft, Color: Blue
Colors may vary. I really liked this, it was the perfect size and that perfect combination of soft and fluffy, but not being "too fluffy" and looking like a shaggy dog that needed a haircut. My only complaint was the color. Supposed to be blue, and I know monitors and lighting distort stuff but this was an obvious turquoise/teal. Much much greener than I was looking for. I could have made any variant of an actual blue work from powder baby to practically navy, but not this. I had to return, but other than the color, this seemed to be a very nice rug. Sad the color was so off.

Verified Real Sheepskin, High Quality, Looks Great
Color: Black, Color: Black
I was initially a little skeptical of the “real sheepskin” claim, so I really appreciated how much effort the seller put into transparency and verification. This console cover comes with a detailed information sheet explaining how to identify real vs faux sheepskin using a burn test, and it also includes samples of both genuine and fake sheepskin so you can see the difference for yourself. That alone gave me much more confidence than most listings. To verify the actual product, I carefully tested a very small, hidden area on the backside of the console cover itself. While the hair did briefly ignite (which initially gave me pause), everything else aligned with real sheepskin: The smell was unmistakably burnt hair, not chemicals or plastic The fibers did not melt like synthetic material The burned area turned into soft, powdery ash, not hard or plastic like beads Comparing my results to the included info sheet and photos, it clearly behaved like genuine sheepskin. Based on the smell, texture, and burn behavior, I’m fully convinced this is real. The cover itself is very soft and well made. The black color is a true black (not faded or grayish), and it adds a nice upgrade to the interior. My daughter mainly wanted it for the look and the softness, and she’s been very happy with it. It fits well on a standard center console and has stayed in place during regular driving. This should work nicely for most SUVs, sedans, and crossover vehicles that have a center console between the seats. This was for a 2019 Acura RDX. Overall, this is a quality product, and the seller’s claims about authenticity were accurate. I really respect that they give customers the tools to verify it themselves. Highly recommend.
