Yeh I know most injectors require a spacer, I was expecting to have to use a spacer, but 1cm is huge. If they fit, it's going to be very very close to hitting the plenum. Should be able to work something out though.
The seller said he was selling his car so he wasn't going to bother upgrading the injectors. He never installed these injectors in his car, he bought them and had them sitting around for a year before he decided to sell his car along with all the mods he had planned for it. Which is why the Sard boxes made me curious. As well as the fact I got them so cheap when they are basically brand new. I just wanted to know for sure what type of injector they were, not that I was putting some crappy Chinese rubbish in. The boxes are very faded and worn as well.
I'm not normally paranoid, but with my fuel system I am. Not all people are out to rip people off, but some are, so I thought it better to be safe than sorry. I had no intention of buying second hand until these came along, the guy seemed genuine and I got them really cheap so I couldn't go past them.
