602/604 Valve Cover Breathers ( SOLD AS INDIVIDUAL )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!

Love it!!
Size: Iphone 17, Color: Light Blue
I got the Miracase Magnetic iPhone 17 Case in light blue, and it’s excellent. The case fits my 6.3-inch iPhone 17 perfectly and works flawlessly with MagSafe chargers and accessories. The military-grade protection gives me confidence — it’s shockproof, scratch-resistant, and feels very durable without adding unnecessary bulk. I also love that it comes with a screen protector included. The anti-fingerprint translucent matte finish keeps the phone looking clean while providing a nice grip. It’s easy to install, feels premium, and the color is subtle yet stylish. If you want solid protection with MagSafe compatibility and a clean, modern look, this is a great choice.

Great case, bad magnet.
Size: Iphone 17 Pro Max, Color: Dark Blue
The case itself is very good. It fits well on the phone. It’s not bulky at all and it seems pretty sturdy. The only problem is the magnet in the back is very weak. Besides that, it’s a great buy.
