HKS 4mm Vaccum Filter

When you're working on the engine, especially if you're cleaning up the intake system or replacing vacuum lines, keeping things clean is key. This HKS 4mm vacuum filter is a small but important part for maintaining the integrity of your engine's vacuum system. It's designed to catch any small debris or contaminants that might otherwise get pulled into sensitive engine components.

This filter uses a 4mm barb fitting, making it a straightforward addition to many existing vacuum lines. It's a well-built piece from HKS, a brand known for its performance parts. While it's a simple component, using a dedicated filter like this can help prevent issues down the road by ensuring only clean air or vacuum is being drawn into the engine.
