Does anybody know what to buy these o-rings besides a dealership? My local dealership wants over $25 for both, which is crazy. Thanks
 

I always thought thought you can't just buy the o ring you had to get the screw and cap.

Anyways STM Motorsports has the screw, cap, and o ring for $12.

DSM then OEM Mitsu parts and it's in their.

Or give the always great JNZ Tuning a call for OEM parts
 

Your local ace hardware has the biss screw oring. They probably have a iac sized oring too. Bring the old ones with you so you can compare.

Sounds like a plan. I didnt want to pull the orings out but since my car is down for a diff swap I'll check out Ace hardware.

BISS O-ring: You need a #5 O-ring (3/8" x 1/4" x 1/16")

I found some at work that fit, I have yet to try it out. But my BISS oring was hard as a rock.
