Toyota Cylinder Head 2TR assembly - non EGR type 171549-1
171549-1The Toyota 2TR Cylinder Head Assembly (Non-EGR Type) 171549-1 sits right into the 2TR engine without fuss. Most mechanics choose this type when the original head shows heat marks, coolant loss, or uneven compression across the cylinders. Once fitted, the engine usually idles steadier and holds its power better, especially in vehicles that run long hours.
Another thing worth noting—this head follows the non-EGR layout, so you avoid the clutter and heat that usually sits around the EGR passages. Shops working on older 2TR engines often prefer this cleaner setup because it keeps the rebuild straightforward.
You can carry out the job with standard tools. The surface holds the gasket well, and the ports sit in the right shape for the 2TR airflow pattern. In most cases, technicians say the head sits onto the block without any alignment struggle, which saves time during the rebuild.
