Overview
The Holley LS1/2/6 Ultra 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. Plenum top is machined for a standard "large" 6-1/8" x 3-1/8" burst panel. SFI approved burst panels, burst panel frame sets, and gaskets may be purchased from various manufacturers such as Allstar Performance or Specialty Fasteners The Ultra 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. The 300-623 Ultra 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.

- Designed for GM LS Gen III and IV engines equipped with GM LS1/2/6 (cathedral port) cylinder heads

Nice sink caddy
Color: Gold, Color: Gold
It was exactly as described- looks nice on my counter. I haven’t bought the scrub brush I want yet to put in the taller space but it def dries fast anytime water gets on it. I like the look on my counter space. It’s not flimsy, I like the color of the gold.

Effective!!
Color: Black, Color: Black
This caddy keeps my sink organized. It absorbs the water when I place my sponges on it and its super easy to keep clean. I squeeze as much waster as I can from the sponges so it doesn't wear out. I've had this a little under a year and it has held up exceptionally well.

Perfect for beside any sink even dorms
Color: Black
I bought this for my son for his dorm room for his sponge for washing dishes and for him to put his dish soap and his hand soap for everything that he could keep it all tidy because he’s actually quite organized and he actually really liked it and it looked very neat. It’s easy to clean. It wasn’t too big everything fit perfectly for the Myers hand soap, and dish soap. The color is neutral almost masculine is gray and black. And there is no issue of it falling because he kept it on a side table away from the sink so that nobody else would use it so it would be just his.
So It was altogether and kept everything organized. He really liked it.

Less mess, more style!
Color: Gold, Color: Gold
So happy with this purchase! I was a tiny bit wary buying an item without any reviews yet, however I saw that the other caddies from this brand all had many positive reviews and seemed to be good quality. The diatomaceous earth base of this caddy elevated this option to me, so I went for it. I've had it out for a few days and am extremely happy that I went with this option! It absorbs water super quickly, so there are no more rings and residue left on the top of my sink, and it makes my countertop look that much more cute and put-together. Heads up it is a little deep compared to some other trays/caddies; I knew this ahead of time so planned to put it directly to the side of my sink so that it did not overlap. I think the size is worth it, since it accommodates about 2 soap products and has plenty of adjustable room for bottle brushes, sponges, drain stoppers, and whatever other items you need. Overall, I highly recommend!

Sturdy and does the job well.
Color: Black
Very stable. Have a narrow ledge on my sink and it balances great without falling. Holds all my sponges and brushes and dish soap. Hasn’t rusted and I’ve had it for a while now. Looks nice on my sink. Keeps my counters dry and my sponges mold free.
