2ZZ Rocker Shaft Plug Service

Eliminates the issue of dislodged OEM freeze plug installed in the rocker shafts. This is a common issue we have experienced in both street and racing applications causing malfunction of the VVL (aka cam switch-over). We can service your shafts or we can also provide new ones with the modification already completed. The below price is for the machine service and plug per rocker shaft.
