Best Engine Internals & Accessories for 2008-2014 Ford FG Falcon

The Barra inline-six is one of the toughest production engines Australia ever built, but like any performance platform it rewards attention to the parts that don't make the dyno sheet. Engine internals and accessories cover the unglamorous hardware that keeps oil where it belongs, seals the block against leaks, and gives ancillaries a solid foundation under boost — on a modified FG, these details matter more than most expect. Freeze plugs and welsh plug kits are worth upgrading proactively on any Barra that's seen heat cycling. Brass over OEM spec is the straightforward call. Breather systems deserve equal attention — a quality billet -10AN screw-on breather in place of the factory cap is a basic step that pays on boosted or high-revving builds where crankcase pressure becomes an issue. For plumbing and bracket work, Proflow's billet oil and water line feed bracket kits are a popular choice on Barra XR6 builds. They clean up the engine bay and offer genuine fitment security that flimsy OEM-style mounts can't match. Pay attention to application-specific fitment when sourcing crank and cam sensor connectors. BA/BF and FG share enough across the Barra family to cause confusion — the wrong plug will cost you diagnostic headaches before you've turned a key.
