i agree. their high end filters like k&n, mobil 1, and royal purple are excellent. the cheaper offerings like super tech, stp, ac delco, etc all have plastic tubes and end caps. there are better choices like purolator or wix. they use plastic because it's cheaper, but still charge you, the consumer, the same price
