what do you think of them and do they do the same job as the conventional ones
well i wont be buying one or two for a spare, ill just keep using oem, i dont see how you could be adding metal to the oiling system though they have an stainless steel screenon the out side . do they have metal on the inside too?:xx:ive seen a few of them (dont know which brand) start to brake down and come apart...
not the best idea in my mind to add metal to the oiling system
IMO use OEM and change with every oil change...
