How do I know the difference from looking at a EFI system max and a EFI system max 2. If possible please provide a link to a pick. I have been searching with on luck.
The Holley Systemax intake for 5.0 mustangs was part of a kit, which included a camshaft, timing chain, and systemax plaque to be mounted on the stock upper intake, and the kit was 50 state legal. The original systemax was a LOWER INTAKE ONLY, same overall design as the stock lower intake just with better flowing ports, and was meant to match the stock upper intake.
The Systemax II is the polished upper and lower that 99% of people mean when they talk about the "systemax intake" because most 5.0 fans have never even heard of or seen the original systemax lower, and is the same intake currently found in the Holley's Systemax II kit for 5.0 mustangs.
