I'm currently installing the spacer with a Steg. ported blower. For those that have installed the spacer, are the Z-tubes a little tight going in intercooler and intercooler cap? My Z-tubes are a very tight fit and require a lot of work to wiggle in. I'm afraid once I get them at least in place that I won't be able to minipulate them if need be to line them up with the intercooler cap.
