The 1jzgte semicircular half moon's only came in the JDM market 1jzgte engines. These are the pieces that fit in the back of the head that seal the rear part of the camshaft. These can often go missing or break when removed for machine wore. Our price is for (1) half moon but you will need to order (2) to replace both the intake and exhaust. This fits all 1jzgte variants.
