Re: Removing Resonator Box
there is a 10mm bolt to the left (your left looking into the engine bay) of the throttle body... remove this, loosen the hose clamp on the throttle body, slip your pcv hose off the oil filltube (its generally ziptied to the resonator, at 150k it may have been cut LONG ago). Pop the clamps on the top of the air box and release the top from the bottom. From there just pull it forward (towards the front of the car to remove it. You will see there is a post that is long that you must work back into its home when going back together.
