Summary

These are caps to cover the Intake ports on the lower Intake Manifold on the Toyota 2GR-FE Motor . This can be useful if you have taken off the upper manifold for cleaning, changing ETC.
The cap leaves a few mm of space so its not an air tight fit. You can add an O-Ring too it if you need a tighter fit, but I used a rubber band wrapped around it.

For all the 2GR swap people that are looking for that perfect Manifold #3 , IYKYK.
