I've read for many years about how bad it is to have cardboard glued to a fram filter instead of steel,..... well I just bought a new filter element from Toyota for a corolla 09 1.8 and guess what , all you get for 7.00 cdn is plated paper filter with no cardboard or metal to keep everything in place.....what was so wrong with the carboard then , or why it is so good to have metal ends........
