Had a problem with how the plugs were packaged. I called customer service and they sent new plugs out right away. Great follow-up and great service. Will do business with them again KRW
They work, but three stars cause they’re overpriced.
The spark plugs are fine , good aviation grade but they are way out of price at $76 each, the average aviation plugs are $ 35 to $45. I use hose sparkplugs are on a 30 years old Revmaster engine, today Revmaster have change their ignition system to use NGK sparkplugs that cost $3.75 each I understand why.
