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)

Thick, NOT sheer, does not blend or absorb.
The spray is completely white and thick - absolutely NOT sheer in any way whatsoever. Out of the can it is chalky white, heavy consistency and is the same on the skin. Does not spread or rub in easily at all. Streaks everywhere, even after playing or being in water. I wouldn’t say that how it stays on the skin is a testament at all to its SPF protection, I think it’s just whatever sticky ingredients are used to mix with the zinc. Definitely would not purchase again or recommend.

Works
First this is zinc oxide. It is going to keep you from getting burned but will be able to see it. My family has yet to get sunburnt when wearing think brand sunscreen. To me that is what matters the most

Loved it! Buying again!
My husband usually only uses spray sunscreen, it was so awesome to find him a mineral based spray. The spray function on this is really smooth and makes applying really really quick. I will be buying again, this is definitely our staple sunscreen.

This product is not Sheer! Leaves a very visible white cast.
Don’t let this one fool you. Although this is a great brand and it does its job when it comes to sun protection, IT IS NOT SHEER! It left the worst white cast on my brown skinned baby. Left a really white cast on myself and I’m very fair skinned. Only reason I’m giving it 3 stars is because I purchased it because it claimed to be sheer and it is not.
