FI blower spacers

Did a search and really only finding old threads on them mainly with early feedback on them. Seems like several people have been running them. About to pull the trigger and wanting to see if those long time users are still happy and would do them again. My IAT is constantly 150+ (even in only 80-90 degree days) as traffic sucks royally and I think my SC is just heat soaking. My intercooler Temps are normally pretty good (20 or so degrees above ambient) but IAT never really comes back close to that after sitting in traffic for a while.
