10 years ago I came across a few posts talking about black flakes and I followed those posts from Zenseeker and Toyota Nation.
I recently replaced my spark plugs and decided to replace my flake filter while at it. I wasn’t expecting anything, but when I put the flake filter on the ground, some black flakes (small) came out on the paper towel.
Here is my 10yr verification about the black flakes in supercharged Previas. They exist and the filter worked!!
