525 Valve Cover Breathers ( SOLD AS A SET )(NOTE: This is one front and one back)The common misconception about valve cover breathers, is the filter media used in your most common breathers is for filtering air into the engine. This is false. The motor experiences constant blow by, therefore, constant pressure is being emitted from the crank case. As your "filter" clogs up with oil & dirt during racing conditions, the rate at which the engine can relieve the constant pressure slows down. Increased crank case pressure puts pressure

The common misconception about valve cover breathers, is the filter media used in your most common breathers is for filtering air into the engine. This is false. The motor experiences constant blow by, therefore, constant pressure is being emitted from the crank case. 

As your "filter" clogs up with oil & dirt during racing conditions, the rate at which the engine can relieve the constant pressure slows down. Increased crank case pressure puts pressure behind the pistons, causing you to lose power the more the filter media gets clogged. 

Our Breathers are TRUE breathers. They have no filter media and are free flowing. No more clogging, no more crankcase pressure, and no more power loss throughout the race. The pathways inside the breather also allow for you to wash your racecar without ever having to take them off. THATS RIGHT, no more duct tape covering your valve covers. 

Will these breathers gain you power? No, but will they let you keep your power throughout the race? Absolutely!

Great option for a professional looking backdrop
Color: Black, Size: B-102''-3 Panel
I decided to try these wall dividers for my home office space since it does not have a door. I wanted to have my video calls without the rest of the room in the feed to give it a more professional feel. These being on castors make them super easy to move into position and roll off to the side when not in use. They are stable, much more than the folding screens I have tried in the past. That they are connected by the middle piece and not the top/bottom of each other allows you to adjust the positioning to your needs. Overall, this did exactly what I needed and was an affordable option. I also like that they are highly portable: if you want to take them for a booth or event, the poles all disassemble into manageable lengths that easily fit in a car and take very little time to set up again. The only thing I would change is to include a bag to store them in for transportation.

if you are going to be moving them a lot, buy something more sturdy.
Color: Black, Size: Wheel-6 Panel
I use these at our churchc. They are pretty good, not terribly study and the screw that hold the faabric have pulled out in a couple of places. But they wqould work especially well if you were not constantly moving them as we do. They are a bit of a pain to assemble.
