I am using a HKS filter and am very happy with it after over 20K... it doesn't require oil and I've successfully washed it twice with out foam degradation or problems like I had with the oil type filters...CuriousJ0N said:

I found that the K&N brand filters are manufacture by these guys....in pipercrosses competition line they have a dust cover eerily simular to that of what Amsoil has on their filters...they can build to spec so if you want a filter like the Amsoil or K&N that fits properly they can probably do it for you...
FYI the Tacoma 3.4L filter is the same as the 93-98 Supras...or the Hilux 3.4L
