Suit Single GM LS 102mm Throttle Bod

Part Number: HO300-123BK

The Holley GM LS1/LS2/LS6 Modular Hi-Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing LS1/LS2/LS6 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost.

It is a keeper for sure!
Style: Steam Mop
This is about 100% better than I ever imagined. It has every feature I want and none of the stuff I don't want. It has a SUPER long cord, it heats up quick and works exactly as it is supposed to. I steam cleaned everything from my stained concrete floors, THE ENTIRE COUCH, and low pile area rugs. Love this thing and SO MUCH cheaper that the competing brands.

Great and affordable cleaner
Color: White
Just got my B&D steam cleaner. I really like it. It is quiet and makes quick work of cleaning the floors instead of scrubbing with a mop. It works great on my floors especially the wood and flat surfaces. I tried it on the ceramic floor and it definitely helped! The problem now is the grout, the cleaner can’t really reach that. This cleaner is light and easy to use. Yes, the cord is short but the extension cord helped a lot. If you order one, make sure to order extra pads because you go through them quick and it only comes with one.
