Hey guys, I bought these sidefeed injectors from a friend a few weeks ago but decided to convert to topfeed at the last minute. The guy I bought them from had them for about 3,500 miles, he went to a bigger setup and E85 last month. They go for around $630 online (http://www.summitracing.com/parts/dwk-02j0008504/overview/), I'm asking $350 Let me know if you have any questions for me, thanks! -Art
