Review on Dorman 911-702 Vapor Canister Purge Valve: The Perfect Fit for Mazda Models - Black by Chris Munns

Having bought 4 of these (probably 1 every 20,000 miles) costs a breather valve on my Mazdaspeed 3. There aren't many options to work with here but if you need a bleeder valve, it will take you some time to blow it. Fixed: The last one I bought lasted a few months in the harsh summer heat. There's something about them that falls short when compared to an OEM device. So far I've gone through as many of them for the cost that an OEM unit would cost me. I've more or less given up on the Dorman part. I would suggest buying an OEM unit instead, but if you are in a tight spot and money is tight. I understand how people can get it. I have a feeling there is a reason the Bosch part costs five times as much.
