Do one oil change myself and it’s more than paid for.
Color: Silver, Color: Silver
It is 74 mm. It’s nicely made of cast aluminum. It has a rough cast finish so it shouldn’t be difficult to hold on to. It does fit my Lexus filter and the price is very reasonable. It also fits the oil filter on my 1999 (antique) Harley Davidson Heritage Classic. Which is the primary reason I ordered it. I don’t know this for certain but I suspect it will fit all HD EVO engines. That would be 1984 through 1998 except the Heritage which didn’t change to the 88 Twin Cam until 2000.
