These are 3/8" 6061 aluminum plates laser cut for those wanting to do the heater core bypass mod on the 1jz and 2jz engines. This blocks it off, you can drill, tap, weld, whatever you wish to do to continue the coolant loop and get rid of the hard line that goes behind the exhaust manifold. This is a simple solution for the fabricator that does not wish to buy a pre made kit.
These are straight from the laser cutter, not deburred to keep costs down.
