distributor housing. Fasten the air line into position by hand with two M6 x 16 hexagon-head bolts (cylinder bank 4 - 6), and tighten the union nut
a/f 22 with a torque wrench. Screw all four M6 hexagon-head bolts tight.
Tightening torque for M6 hexagon-head bolts
10 Nm (7.5 ftlb.)
Tightening torque for union nut a/f 22
25 Nm (19 ftlb.)
