I was a LONG time user of Amsoil foam filters and LOVED them. When Amsoil revamped their filter line up I was initially kinda hesitant. But after finally putting one on and getting an oil analysis after using it for a while and seeing a reduction in silicone, Im pretty happy with it. They are still good for 4yrs or 100,000 miles and you dont have to worry about contaminating your MAF sensor.
I never had a problem with that but I have run across many that did so I think the current Amsoil filter will help aleiviate that.
