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

29 years of riding a Harley, THIS is the best sun protection I have found for long SUNNY day rides!
Size: 6 Ounce (Pack of 2), Style: SPF 50, Size: 6 Ounce (Pack of 2), Style: SPF 50
This is my "Go To" Sunscreen of choice that I find is the best to quickly spray my arms down good before a long Harley Motorcycle ride! I have tried many brands and styles from creams to face specific to lip balm but this one can does it all in my case! I quickly spray my arms ( no rubbing in required ) and a quick spray in my hand and I then rub my nose and ears , face and i'm ready to ride and I am protected! Most times I only apply this product once a day and works better than anything else for my needs. I am light skin but I have ridden lots this Summer and my arms never burn and now have a deep tan as we are entering fall... I made the mistake of trying a store brand that looked like this product but was oily and never used it but once! This Banana boat once sprayed on my arms, I never think about it again as its gone but still protecting my skin! This is the best I have found after 29 years or riding a motorcycle to protect my skin with the least amount of trouble , No strange or tropical smell, NO greasy feel just quick applied lasting sun protection that has proven itself mile after mile! The BEST Sun product I have found!

It is quick to apply and I've never gotten a burn with it. It doesn't leave marks on my clothing.
Size: 6 Ounce (Pack of 2), Style: SPF 50
I've used this product for years. I spray it into my hands to apply so it doesn't go out into the air. I have never gotten a burn with it and it is. so easy to apply. I don't have to worry about white marks in my clothes. It doesn't take long to apply.

Affordable and Effective
Size: 6 Ounce (Pack of 2), Style: SPF 50
It’s really good for the price and super easy to apply. I would recommend having someone help with your back or harder-to-reach areas, because any spots you miss will definitely show if you’re out in the sun for a while. I’ve used this for a couple of years now, and it’s one I keep going back to. If you have more sensitive skin, there may be better options out there, but I personally haven’t had any issues with it so far.

Us it Every Day
Size: 6 Ounce (Pack of 2), Style: SPF 50
This is really a great product and easy to use as a spray. I bike ride every day and my ears/face are exposed to the Florida sun. I use it primarily on my face every day. A moment after a quick spray, the product dries, is not sticky, etc. This will become a recurring purchase.

Good protection from the sun.
Size: 6 Ounce (Pack of 2), Style: SPF 50
Does a good job keeping sunburns away. Spray sunscreen never lasts as long as rub-in sunscreen (ie, the bottles run out quicker) so it seems pricier to cover the whole family, but we keep this on hand for days we'll be outside!
