I had a small hole on my stock hose so obviously I needed a new one. I chose this one because it was silicone and I could have a red one to match the red silicone PCV lines that I ordered from Z1. This hose as well as all of my other silicone hoses I purchased from Z1 look and function fantastically. Because hoses are made of silicone they will last forever. The quality is unsurpassed and they are a perfect fit!
