Um I fail to see how that will silence any thing. The spider valve dose not stop fuel flow. It is a secondary valve meaning the fcu is the primary ICO and the valve when fuel flow is less than spring px closes. This stops dripping into the nozzle and stops after run giving as it says a cleaner fuel shut off. But once again what would I know.
One other quick thing. Lop is not new at all so for those of you that think it's is I guess you need to look back. It was also taught at tech. I no I won't be advocating it to anyone at all. It is there decession to do it if they wish and they will get the rewards of a $20 saving in there pocket if they wish to do it.
Cheers.
