Unboxing our Super Tough Porsche 911 Blend Valve Base (4K)

Here's a look at our Super Tough redesign of the Porsche blend valve base (91157105100). This part is notorious for breaking when the screws are undone.
This new part is made from super tough glass fibre filled nylon. The threaded insert has been redesigned so it will not break out of the plastic.
If you are fitting our underdash ducts, be sure to check the condition of the blend valve bases and screws! Learn more and buy on our website: www.classicretrofit.com/produ...
