The factory oil filter location on the Gen III Hemi may interfere with the crossmember or suspension in some engine swaps. These block-off plates & relocation kits allow the oil filter to be moved to a remote location. The block-off adapter screws on instead of the oil filter and the two 3/8" NPT ports on the block near the filter allow installation of the AN hoses for plumbing the remote filter. Aluminum construction with black anodized finish.
