As mentioned above, blow off valves get dirty and stick. You'll lose boost when this happens. Therefore it is not good mod for reliability. However, the factory bypass valve is common to tear and cause boost loss as well. Your best move for reliability is to replace the stock BPV with an aftermarket BPV. Ford racing, Mountune, Turbosmart plumb-back, etc.

Another reliability mod is the FMIC. Cooler charge temps are safer on the engine.

So my choice is an aftermarket bypass valve, not a blow off valve.

In your multitude of threads, you seem to be extremely concerned with reliability. You shouldn't be doing autocross or any other severe-duty events if you are concerned about wear and tear.
