a WOT/window switch

I have a brand new one I will sell for $150. I have decided to not run N20. I allso have I brand new dry kit I will probally sell for $350.

Also a wideband, colder plugs(have some brand new NGK's from LET to sell as well), and a fuel pressure switch if running a wet kit would be a good investment.
