Valve bore plugs on Honda/Acura 4-speed, 3-shaft and 5-speed valve bodies wear and allow critical CPC and solenoid feed oil to leak to exhaust, leading to low CPC pressures and soft or inconsistent shifts. Sonnax 12mm O-ringed end plug 98892-01 replaces the worn OE end plugs and restores critical circuit pressures. Drop-in Zip Valve™ installs quickly and easily.
See instructions for details on end plug bore fitment.
