Be advised

Ok for all you ppl who dont know this yet DO NOT POWERWASH YOUR SUPRA!!!!!!!!!!!!!! :nono: :nono: NEVER!!!!! reason is water can easily get into the sparkplug chamber and cause them not to kick over you can easily get the water out by getting a wetdry vac suckin it all out with that. So this is jest a pre warning dont powerwash or steam clean your supra engine.

I did that once! took me for EVER to figure out why it was misfiring... I don't know why they made them hold water like that...Coolant gets down there easily too. Don't even use a water hose (that's what I did)
