No performance gain. High-flow injectors are available in top-feed as well as side-feed versions

There is no real advantage to side-feed or top-feed, except in manufacturing methods and packaging considerations. To switch from one type to another means changing the entire fuel rail

11mm vs 14mm refers to Top-Feed style injectors and is the inlet O-Ring diameter. No performance gains, which type you need depends on the size of the openings in the fuel rail

Hi-flo injectors are available in 11 or 14 mm inlet versions, you can get 1000cc injectors with 11mm inlets (stock CA18DET is 370cc)

Dimension 'A' - injector inlet O-ring
