Review on Standard Motor Products V311 Valve by Anthony Boylan

This valve is a complete waste of money. As a result of USING this product, i found that it actually made my car performance worse, causing a lot of problems while driving. This product is not reliable and it is clear that it lacks quality .The only good thing about this valve is that it is affordable. However, it is not worth risking your automotive performance over. I would recommend looking for a different brand that produces a much more reliable and efficient valve..
