Frequently Asked Questions

  • What is the Full Flow Extension Adapter used for? It is an extension adapter for full-flow oil system setups on air-cooled Volkswagen engines.
  • What is it made of? It is precision CNC-machined from billet aluminum.

Material & Construction

This component is machined from solid 6061-T6 billet aluminum rather than cast or stamped from sheet, which is why engine builders trust JayCee oil-system hardware on both street and performance air-cooled VW builds. Tighter tolerances at the sealing surfaces mean fewer weep leaks over time compared to lower-cost stamped alternatives.

Installation Notes

Always install with a fresh o-ring or gasket as applicable, torque fasteners evenly in a criss-cross pattern, and re-torque after the first heat cycle. Check for seepage at the sealing surface after the first drive and before every oil change thereafter.

As an aftermarket upgrade rather than a reproduction of the stamped-steel factory piece, this JayCee part is built to outlast and outperform the OEM original while remaining a straightforward bolt-on for anyone comfortable with basic hand tools.
