Would the ones in the picture of any help? They are out of a 2009 2nd Gen Renesis. The numbers are: green 827 12 , 297= 500-1220 . Brown 827 08 , 297500-1230 . I can not interpret these number.

Hi Richard,

I suspect, but don't actually know, tha= t I need 400+cc(normally aspirated Renesis). The yellows are somewhere = between 380 & 430 cc, depending<= /a> on where you look & what pressure they run at.

Thanks for checking, & if it turns out that= my research is wrong on the flow figures, we'll need to talk further. :-)<= br>

Charlie,
are you still looking for injectors?
