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 300-600 is the lower manifold in the 300-620 complete kit. Offering this separately allows you to select your components individually as you build your system. 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 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.

Maybe the best glove in golf! Wife loves the glove!
Color: White, Size: Medium-Large, Style: WeatherSof Prior Generation, Configuration: Worn on Left Hand
My wife loves her glove! Comfortable, fits well and is pretty durable in the short term use. Time will tell if it’s durability is long term or not.

Part of Your Skin
Color: White, Size: Large, Style: WeatherSof Prior Generation, Configuration: Worn on Left Hand
Golf clubs are worn to steady your grip, keep the grip clean and most of all--keep the club from flying out of your hand. This glove does the trick and even after 18 holes feels invisible--like part of your skin. It is snug but not constricting. The glove is part mesh and has strategic cutouts so that it breathes. I golf for fun and bought this at the suggestion of a very fine golfing friend. It is well made for a good price.

Women's Golf Glove
Color: White, Size: Medium, Style: WeatherSof Prior Generation, Configuration: Worn on Left Hand
Love the classic fit. Some other brands may need to be medium-large, but this medium works well Wore it yesterday. Good grip. Removed glove on each hole before getting on the green. Our current weather is hot and humid. Still fairly easy to remove glove! Soft and lightweight. Worn on my left hand. For weekly use in league play. Would recommend. Also like the extra pad on heel of your hand. Plan to only wash by hand In woollite and drip dry. Wish it came in pink, but bright white looks fine. Price is comparable to other brands i have purchased.
