I have a TRX420FA6H. 2017 oil filter and air filter were not suitable for my Honda. So I paid $58 for 3 gallons of oil, 2 pints of gear oil and a spark plug. In addition, 3 liters of oil is not enough to fill the crankcase. This purchase prompted me to make an unexpected trip of 80 miles round trip to the nearest Honda dealer to get the part I needed. Not very impressed.
