runner ports with masking tape. Now is a good time to install the
new hi-performance Denso Iridium spark plugs. NOTE: Spark
plugs are pre-gapped. NOTE: Before removing old spark plugs,
use compressed air to blow out around plug recesses so that any
dirt will not fall into cylinder. Put anti-seize on threads!

plastic air pump hose and vacuum line from combi-valve,
secondary metal air pipe flare nut from combi-valve, and loosen

rotate pipe towards driver side of vehicle to allow removal.
Remove three bolts using a 6mm hex driver and one bolt using a
5mm hex driver – lift out heat shield. Remove combi-valve
assembly using a 5mm hex driver. Remove combi-valve gasket
