yea I'm actually making a bracket to support the filter, it'll bolt to where the airbox was and to the side where the snorkel was, I'll use the stock bolt/bushing for it. I purposely left the stock intake and only replaced the bax with the Filter so it will have some flexability when I mount the sensor to the bracket (I'm not much for bling and don't want to spend alot of money for an intake I'll have to modify anyways)

I figured the motors are close to identical, just not sure what years are compatible. so the EJ20t of about the same year are compatible?

 

i THINK any header from a 90-up 4 cyl subaru engine will work. Ask at bbs.legacycentral.org, i don't have much experience meddling with this particular car, it's my daily.
