I just came from WalMart and, after all the talk about their "E-Filter," I thought I would check them out. I had used the old S.T. filter once, about 4 years ago, on my Civic. I knew not to expect much, based on the discussion here, but I was still surprised at what I saw. They look like they were "reverse engineered," to sell at a certain price and return a certain profit margin. Don't think I will try one of the new ones.
What does E-Filter stand for?
