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 low height to aid the packaging of a plenum mounted air-to-water intercooler in a top-feed configuration. The 300-620 top-feed plenum entry configuration is designed to allow the included Hi-Ram 105 mm plenum top to be fitted to a low-profile base intake manifold. 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.

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
  • Modular design allowing the use of the included top-feed plenum entry
  • 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
  • High volume fuel rails and mounting hardware included with ¾”-16 o-ring ports (8 AN)

Clean up dirt you didn’t know you had
Style: Steam Starter
This floor steamer is perfect for quick cleanups! It’s incredibly lightweight and easy to maneuver around furniture without any strain. I love the easy-change pads—they secure firmly but pop right off when you're done. While the water tank is on the smaller side, it heats up almost instantly, so refills aren't a big deal. The only real downside is the lack of an "off" switch; you have to unplug it to stop the steam, which is a bit of a hassle. Aside from that, it’s a powerful, no-fuss tool that really gets the job done!

meh!
Style: Steam Starter
I used to have a bissell steam cleaner for floors and it took a second to heat up and once it did, it steamed continually and I could turn it up or down or off. Sadly, it started to leak so I purchased this one. This is not at all like the one I had. It doesn't steam continually and the only way to turn it off is to unplug it. It doesn't clean as well as the one I had. I'm not a fan of this one. But sadly I threw away the box so now I'm stuck with it. It says you have to pump it to have it steam, almost like an iron for clothing, it steams for a second then stops.

Best steamer on market hands down
Size: Standard, Size: Standard
If you want to really deep clean your home then this will be your best friend. Comes with several different attachments which is great. It’s light weight so not heavy to carry around. So easy to put together or change attachments. They give you a measuring cup for the exact amount of water you need with a funnel so no mess putting water in. Heats up super fast which is awesome. Like i said light weight but strong steamer. The first thing i used it on was my oven which is 8 or 9 years old. From cooking especially holidays there was grease etc on it. I used the oven cleaners that say removes grease with one wipe Nope it those products actually ruined top of my stove made it dull and even other parts almost a rust look which I am not happy with. Wish I knew about this amazing machine before I ever used the store bought oven cleaner. Like I said it comes with several attachments ones for steaming your floors amazing. An attachment for grout also did an amazing job I was shocked my shower looks brand new my floors look brand new also. Another attachment is for steaming shower doors, walls, furniture and clothes works awesome. Another attachment for hard to reach places super amazing. Oh and the handle can come apart so you can make it long for when your steaming floors then make it smaller to carry around to do all the other steaming you want to do. Best part is that it didn’t break the bank the price was well worth it. I first saw this steamer on TickToc like with other items I have bought. But my go to place to see if these items are on Amazon cause Amazon is my go to place to shop, also the prices are always cheaper and you can get it in 2 days or other things I bought within hours. Where tik tok it takes weeks to get and always more expensive. So thank you Amazon for being an amazing company. If i could give more stars for this steamer I would give it a 20 star that’s how great it works. One thing I forgot to do was take a picture of my stove before but I did after. You can see where those store products ruined areas I mentioned. That was not caused by this amazing product.

Great all-in-one steam cleaner
Size: Standard
The Schenley 19-in-1 Steam Mop is super versatile and easy to use. It heats up quickly and the steam is strong enough to clean floors, grout, and bathroom surfaces without any chemicals. I love how easily it switches to a handheld steamer—feels like multiple tools in one. The build is sturdy and it maneuvers well. Overall it’s a great value and works really well.

Great Lightweight Steam Mop!
Size: Compact, Size: Compact
I’m really happy with the Schenley Steam Mop. It heats up in about 15 seconds and is ready to go almost instantly. It works well on my hardwood and tile floors, removing everyday dirt without needing any chemicals. It’s lightweight, easy to maneuver, and I love that it stands on its own. The washable pads and adjustable steam modes are a nice bonus. The water tank is a bit small, but for regular cleaning it’s perfect. Great value and very convenient for quick, effective cleaning!
