Any of you that might have a 90-94 Legacy with those air filter boxes that screw down, I was able to install a 95 Legacy one that has the wrap around clips.  Everything bolted straight in.  The old airbox was missing 3/4 screws to keep it shut and had a tab broken off.  

 

 

Thank you for this. I love easy swaps like these. Inexpensive and simple! The best when you have a busy life.

Good to know. Those old screw types are a PITA. Will have to put this on my to-do list.

They were fine when new but over time all the nuts in the back of the bottom housing have fallen off.  The clips are so much easier to deal with and its nice to not need a tool to get the air filter out.
