Gen 1 B58 Pcv Diaphragm Replacement

This PCV Replacement kit is designed to provide everything you need to easily replace your old, cracked, or leaky diaphragm with a new one, all without the hassle of replacing or removing the entire valve cover. A common problem in the past was the brittle cap breaking during removal, which could be frustrating for DIY enthusiasts. To address this, our kit includes a replacement cap, ensuring a smooth and worry-free installation experience.

Thicker and more robust diaphragm compared to stock, leading to a longer life!
