Should have posted in the newbie section. You can find a blow off valve at any reputable performance parts shop. Why do you want to upgrade yours, if you don't mind my asking? Have you modded the car at all? If not yours will be just fine, until you turn the boost up. Please tell me you don't want one for the noise...

 

next time, please use the search function...
