A number of performance filters use the stainless steel filter media found in Trufilter and all of them have been shown to filter 35 micron and smaller particles about 90% better than paper filters while maintaining much higher flow rates. I can only tell you from my first hand experience, but I love this thing. I've had it on for three oil changes now, and I have not a single complaint.
Due to the better filtration, you can go 7500 miles between changes if you want. I still change oil every 3000 miles, but I'm anal and I want this truck to run forever.

I believe the stock filter is the only paper filter for the FJ...I was saying that it says "35 Microns" dosen't say the number that it filters down to, THAT bothers me. Lol, I just watched the Two-Road to Baja video with the FJ's, noticed the black second place winner (TRD Baja) actually used the K&N filter over the TRD one...kinda odd.
