Hey guys, i used this spool valve for just a few weeks before changing my combo so here it goes up for sale. I modified the valve diaphram arm so it can fit into a tighter space or it can be used just as build in the original arm location, either way, it works perfectly. This valve is made by Sound Performance, it is made for a T4 flange and is a stainless flange. A spool valve helps you build boost much faster (fast spool) and also must be used with a divided (seperated) exhaust housing on your turbo. If you are not happy with the valve when you receive it, i will refund your money. These sell for nearly $500, the first $300 gets it and i will ship for free to the lower 48. Paypal is preferred. Please PM if any questions Thanks
