Hello Saab family, I currently drive a 2004 arc sedan and am from SF bay area. CA. Ive had this car for a little over 2 years and love it. Ok, so I volunteered to help a friend change the spark plugs on a 2008 aero. Everything was fine until #5 when I broke the hard plastic spout piece on the side of the block. I'm not exactly sure what the part is, but I know its def something w the vacuum. Any ideas?
