GrimmSpeed 08+ WRX/STi AOS - Manual (Page 8)

18. Using supplied ½” Cap, cap off white sensor from step 14. Insert ½” to ½” hose connector
into open crankcase Tee port. Using supplier ½” hose, place ½” hose onto other end of ½” to
½” hose connector and bring hose to one of the bottom ports on the AOS. This hose needs to be
long enough so that it will tuck under the intercooler when it is reinstalled. Place zip ties on
all hose barb connections. Reinstall intercooler. (this includes the outlet hose clamp, BOV
bolts, mounting bolt, and turbo outlet bolts).
19. When intercooler is in position and not pinching any of the new AOS hoses, cut the final
hose from step 13, 16, or 18 and push it onto the AOS. Place a zip tie on it. You're done!
