HKS Shallow Fit Air Filter, 150mm Filter, 80mm ID Opening
High quality HKS air filter, oil impregnated foam, precise internal flow profile/horn for optimal flow and minimal flow loss. Not a cheap Chinese knock off, don't accept a substitute which can come apart and destroy your turbo, only HKS filters use a solid billet aluminum backing for the best strength.
These filters feature shallow mounting depth to clear tight engine compartments. We have tested the 4" 200mm filter to over 640whp with NO power gains when removed from the turbo.
Come with green element, black replacement elements available at extra cost.
