Does any body know what size bolts I'll need to plug the holes for the oil injectors? Also how long should they be? Sorry for asking but the fc3spro site is not working. Thanks.

M8-1.25 sounds right. It's a fairly common bolt at a decent hardware store. This is the fine thread, so they won't all have it. The shortest bolt I could find was still too long, kind of looks stupid sticking out.

I measured it as being 10mm (.388") x 1.25mm (.047"). It was kinda hard to tell if the thread pitch was 1 mm, or 1.25 mm, so you might want to bring the bolt with you. I just used calipers to measure it, somewhere I have a metric thread gauge, but can't find it.

Thanks guys I appreciate all the help. I think I'm going to just go buy both bolt sizes and see which one fits better just to be safe. Thanks for the link about the intercooler also.
