After Sport-Z magazine testing busted the upper plenum myth, most likely sales fell like a rock.

MREV2 Lower Collector + 5/16 CU Spacer FTW.

Also -- Don't forget to do an ECU Reflash (AAM or UPREV) if you do a lot of breathing mods. Otherwise your oem ecu will try to tune around the mods, putting the performance back to factory specs.

There is no issue with a spacer and FI.
