The MPI Automotive FX-278 is a tubular extractor listed to fit the Holden Commodore VT with the 5.0L V8. It runs 1-3/4in primaries in a 4-into-1 layout with 3in outlets.

What does this extractor cover?

This is the header section for the 5.0L V8 in the VT Commodore. It runs 1-3/4in primary tubes merged 4-into-1, finishing in 3in outlets. It covers the manifold replacement on each bank — it's the extractor only, not a full system. The 1-3/4in primary and 3in outlet sizing is matched to the 5.0L V8 rather than a milder engine.

What is a 4-into-1 extractor and what does it change?

A 4-into-1 extractor takes all four primaries on each bank and merges them into one collector before the outlet. That's the layout chosen when you want the runners to scavenge together, and it's a step up from the short cast manifold the factory fitted. On a 5.0L V8 the 1-3/4in primaries set how the headers flow, and the 3in outlet decides how they mate to the rest of your system. Tubular steel sits exposed in the bay, so clearance is checked when fitting.

Will it suit my VT Commodore?

It's listed to fit the Holden Commodore VT with the 5.0L V8. Years aren't published beyond the VT body code, so send us your build and we'll confirm the FX-278 matches your engine and existing system before ordering. We treat the listing as 'listed to fit', not a guarantee, since feed data can be imperfect.
