Chinook Flight Saving 0.6 gph

In case anyone was thinking about this purchase: Our club installed SureFly electronic mags on the left side of three of our planes since May, 2021. (New harness installed also). Our 172L (LYC O-320 E2D) with new Tempest plugs just hit the 500 hour mark since that installation. Plugs are still well within service limits, required minimal cleaning. We've kept excellent fuel consumption records and recorded a .6 gallon per hour reduction in fuel consumption. This resulted in $599.67 savings in fuel costs over this time. So, I would recommend this conversion due to simplicity and appears to well be paying itself.
