A must have for every Rx8. This adapter cuts the injection of the dirty engine oil in the oil pan, and allows you to inject clean 2 stroke oil to better lubricate the apex seals and drastically reduce carbon deposits.
An additional benefit is that now you can safely use synthetic oils and go thicker! (15w40)
You still need to premix after this mod, as you've only solved the issue of oil type, not quantity.
