Hello

I am the second owner of a 2000 RX300 with about 270k miles. From the paperwork history it doesn't look like the spark plugs were ever changed.

I am thinking of changing them along with the valve cover gaskets.

What other parts are needed? The valve cover gasket set that I am looking at has the spark plug tube seals. Do I need to get a new plenum gasket? anything else?

For plugs should I use whatever Lexus recommends?

Thanks

no other parts needed other than the valve cover gaskets. You can opt to reuse your plenum gasket provided it doesnt get bent and intake manifold is torqued to spec.
For plugs, use what is in the manual IIRC..Denso SK20R11 or NGK IFR6A11
