The Engine Oil Filter Support are filter cap tubes that support the oil filter inside the housing. Without The Engine Oil Filter Support the oil filter could collapse due to pressure. Replace only the failed part, and not the entire assembly for a convenient and trouble-free installation. Our solutions are thoroughly tested and inspected, and if you experience any difficulty installing or using our parts, we have a dedicated technical support team of ASE Blue Seal certified professionals ready to help.
