Suggesting that the FLAPS counterman who suggested the Bosch 3300 was not making a mistake. It's just that asking for a filter that fits a Saab 900 or 9000 wasn't giving him enough information to go on. This because tencentlife's instruction sheet wasn't detailed enough to go by. So it seems that what I gotta get is a WIX 51348XP or Bosch D3421, both of which have that 3/4-16 threading that should result in a filter that be less-blowoffable. -- Jack "Rocket j Squirrel" Elliott 1984 Westfalia, auto trans, Bend, Ore.
