My finding? Hai with those small filters flow similarily to a zzp intake with a large filter.
An open cone with large filter flows the best.
Iat with zzp has literally been the same as ambient. Hot air never got better than 5-10* f above. Both heat soak at idle however zzp comes down to ambient at speeds as low as 25 mph. Hai requires 40+ mph for that.
Theoretically best flow and highest temp would be best for fuel economy see hai. For best power a zzp with something other than their crazy ducting. The ducting claim ive yet to test but i will shortly.
