  • Power: Dyno tests showed better than 15% horsepower increase
  • Fuel Efficiency: Fuel savings up to 20%
  • Safety: Tubing thickness 40% greater than standard, no welds inside the cabin air box (vs. up to 60 inches of welds in other systems)

 Applicable to: 172 Skyhawk Models I through P with Lycoming O-320; 172 Skyhawk with Lycoming O-360 Avcon, Air Plains, Williams, or Penn Yann conversions; and the 177/177A/177B Cardinal with Lycoming O-320 and O-360.
