These lower engine mounts are super thick and made of super strong zinc plated carbon steel A36. These engine mounts replace the lower factory mounting points which creates the clearance necessary to run a turbocharger. They utilize the factory bolts with the exception of the three in the picture. The two longer yellow bolts are necessary when running the HPF turbo manifold. The HPF motor mounts work with both OEM motor mounts or aftermarket motor mounts.
