Pros and Cons

Pros

  • Saves significant time on maintenance by removing the need for manual oiling.
  • Ensures uniform oil distribution that is difficult to replicate by hand.
  • Professional-grade filtration consistency matched by top race teams.
  • Reduces exposure to messy chemicals and shop solvents.

Cons

  • Requires careful handling to prevent staining surrounding components during install.
  • Not intended for reuse without a proper cleaning and re-oiling procedure.
  • Specific to the 158084X application, limiting cross-compatibility.

Setup, Compatibility & Care

To install, first ensure the airbox is thoroughly cleaned of any existing dirt or debris. Slide the 158084X filter onto the cage or mounting point as required by your specific vehicle intake design. Ensure the seal is flush against the airbox rim to prevent bypass air. Since this filter comes pre-oiled, avoid using additional filter oils or additives during the first installation. For long-term care, when the filter becomes dirty, use a dedicated air filter cleaner to dissolve the Bio-Oil, rinse, dry completely, and then re-oil using a fresh bottle of Twin Air Bio-Oil to restore its original factory performance.
