Exhaust Care Kits

One order. Two practical tools for smarter exhaust care. FlowRods kits pair an M18x1.5 O2 sensor spacer with a 120ml catalytic converter cleaner.

Two-Part Exhaust Care

  • Compact metal spacer with a wrench-friendly hex base
  • Pour-in cleaner for carbon buildup and smoother exhaust flow
  • No converter removal needed to use the cleaner
  • Each 120ml bottle treats up to 30L of fuel

Choose 1, 2 or 4 kits. Review the kit contents, directions and fitment, or shop cleaners and O2 sensor spacers separately.
