Is any one running these filters?

I tried one once, once, haha I noticed that the engine had a bit more noise especially when cold with that filter. Switched to a wix and the noise almost immediately went away. I'm sure they are a high quality filter, but I prefer wix.

Amsoil makes excellent products but they come at a price. Unless you have a warehouse in your area where you can do direct pickups, the shipping alone makes it not worth while.

I was a dealer for approx 5 years. Ran their oil and filters in all my rigs. Good stuff but again, expensive.

Get a quality wix filter and be done with it.
