 | Graph 1 is a comparison of the BPi Flow Stack and a 3" cone filter on a Honda H22 motor. | |
  | Graph 2 is a comparison of the BPi Flow Stack and the Prototype Engineering Velocity Stack on a Honda H22 motor. |
 | Graph 3 is a comparison of the BPi Flow Stack with K&N Filter RP-4600 and 3" AEM Filter on a Honda B18c1 motor. No additional tuning was performed after the installation of the Flow Stack. |
 | Graph 4 is a comparison of the BPi Flow Stack with and without K&N Filter RF-1048 and 3" BMC Filter on a Honda 85mm built B20 motor. No additional tuning was performed after the installation of the Flow Stack. |
 | Graph 5 is a comparison of the BPi Flow Stack with K&N Filter RF-1048 and 3" K&N Filter on a Honda B17 motor. Motor was tuned with Flow Stack and no additional tuning was performed after the installation of the 3" K&N Filter |
 | Graph 6 is a comparison of the BPi Flow Stack (RED) without a filter and a 3" Injen Velocity Stack Filter (GREEN) on a Honda 84mm Honda B18C motor. Motor was tuned with Flow Stack and no additional tuning was performed after the installation of the Injen Filter. Intake was Injen Shortram Intake, Part No.INJ-IS1420P |
 | Graph 7 is the same comparison of Graph 7, but with Air to Fuel Ratio data. |
