When you look inside, the design is very nice, sometimes they allow more paper filtering area.. I am not always at the Toyota dealer, so they sell three of them at a cut rate, sometimes a dollar cheaper each..I have been looking inside of oil and fuel filters for years. I took up the idea from seeing ads of Nascar engine filter full of rockerarm tips after their 500 mile races. I used to rebuild engines and always cut the first filter open after use for a Look-see??I am trying the Mobil-1 oil filters now as I am going with 5w30 synthetic oil to save my motors and some additional gasoline. By chance what are you calling Bargain filtering?
Arent the mobil1 and K&N just the Purolator high brand filter the same as the yellow grit purolator filter?
