Replace your exhaust manifold studs and nuts with this complete kit designed for Toyota Landcruiser models fitted with the 1HZ, 1HD-T, 1HD-FT, or 1HD-FTE engines.
The factory studs on a 1HZ, 1HD, 1HD-FT and 1HD-FTE engine are extremely common to snap and break inside the cylinder head if not routinely replaced.

Thanks to the guys at HD auto for a simple and seemless experience of ordering parts for my 100 series 1HDFTE, I ordered a unichip, +17 injectors and all the gaskets and parts associated with the upgrade and maintenance work.
All genuine parts were supplied and there were no issues whatsoever. The pre tuned chip has transformed the vehicle and the online youtube tutorial for installing it made things even easier.
Super fast postage and great quality gear.
Had no issues with the service or the parts.
