It can be very good, but alot depends on your environment & care. Figure it'll take you about 5 regualr filter changes for it to pay for itself, which is how your environment comes into play. Some people have had issues due to over-oiling, which gets on the MAF & throws codes. Also, if you don't clean it regularly you lose efficiency quickly. On the good side, if you are careful & take care of it, it cleans better.
Can't remember who it was but I got the impression from another user who said they were a similar type foam element to the Amsoil. I really liked the foam element on the Amsoil while I had it, but the Flowzair didn't like my air box.
Do you happen to have any old school Amsoil filters laying around? If so I'll buy one.
I think AMSOIL had a great filter and decided to improve it into a filter that was not as good as the one it replaced.
I only have two of the old ones, one for each truck and I will never need to buy another one, sorry.
Going back to that UNI filter, I have seen the foam ones, they are nice, but the one I am speaking of was not foam or did not appear to be. It was kind of hard and had a honey comb appearence to it with lots of frame work. It kind of resembled the fuel rod for a nuke reactor. The filter part was pink, and the plastic frame was black. I should reach out to that guy and find out more about that specific UNI filter.
I've been running the UNI filters for a while now and think there the best out there. I'm a amsoil dealer and now tell any customers who want the V6 filter to buy a UNI instead. It's a 2 stage foam filter just like the amsoil and doesn't have the fitting issues of the newer amsoil filters. UNI also makes a cone foam filter that fits the K&N FIPK kit which I'll put back on and try with the new filter one of these days. They also sell bulk packs of foam so you can make you own filters or pre-filters.
I was hoping that someone could give me some suggestions on what to do. I am the original owner and have never had problems until now. I just cleared 90k, and I have a rough idle and loss of power. About a year ago my idle was really rough and my check engine light came on. I got some code...

Has anyone gone through the effort to rebuild their 4.0 SC and was it worth it.? My snout has a very small oil leak and I am thinking about saying f it and sending the whole thing off. Probably 40k miles on the SC.
