Review on Circuit Performance Black Bolt Valve by Andres Black
Bought 8 valves, 2 of them threaded
Basically I wanted to fit 4 new discs to my WRX so I ordered 8 of these (just in case) then installed 2 of them with no problems. The other two threads came off too easily (pictures attached), good thing I bought extra packaging. like a chinese product, but ok for the cheap price, hope they won't let you down on the go.
Pros
- Quality construction
Cons
- ---
