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!

Great for aggressive chewers
Color: Grey
Tuff toy, my yorkie has been trying to tare squeaker out for about 3 days, he works on the fur part but so far it stands up to his chewing, I have gone thru 3 other toys this week so glad thi one works! It lasted 8 days. They need to make whole toy out of material and put fur on top of the tuff material. Once he found out wetting the fur softens it he pulled the seam apart.

Does not stand up to aggressive chewers
Color: Grey
Supposed to be for heavy chewers. My dog destroyed this toy literally in less than 15 minutes. Tore the tail which I sewed back together and then she tore off the nose and pulled out stuffing. Don't know how they tested this. She is only 6 months old and it didn't stand up to her play. Do not recommend if you have an aggressive chewer.

Won't last a day
Color: Blue, Color: Blue
My 50 lb. Pitt bull destroyed this chew toy in 15 minutes. One week later. I'm changing my rating from a one to a five. My girl spent up until now ripping it apart and pulling the stuffing and squeaker out. She had so much fun that I bought her another one. When I took it out of the box for her, she was so happy, she immediately tried to tear it apart.

Lasted 2 minutes
Color: Grey, Color: Grey
Gave it a 2 star bc it was cute and on time. I have a GSD- a mildly aggressive chewer. This toy literally lasted 2 minutes and there was stuffing coming out so I had to take it away. Wish I would have read the reviews before I purchased.

Only Made It Two Weeks
Color: Grey, Color: Grey
This toy easily became my Fig's favorite toy. The squeaker wasn't as annoying as it is in many other dog plushies. However, that's where the positives end. After the first week, there was a hole in the stitching on its neck. I sewed it up, but it obviously did not last. The squeaker went silent after a few more days. I bought it on March 28th, and it is now April 12th. It's just a rag, now. RIP little honey badger. You did well in your short life time.
