Intake setup recommendation

[Geof3]

I'm pretty sure any significant intake mods will require remapping to get anything but more volume out of the setup. Might, in fact, degrade performance. Over they years of trying all sorts of intake "airflow" mods on many cars, usually they just made more induction noise. The ONLY time there was any really change was when the mods we accompanied by a remap that adjusted for the changed A/F ratios.

There's another link with some Dyno results but in my case 74mm TB and larger diameter intake gave circa 5bhp. This was after the exhaust and manifolds which gave just shy of 10bhp.

Is this mod currently on your car, or are your dyno results from your S?

Not saying it can’t happen that some minor change can be had, but to get the most out of any intake/exhaust mod, a custom mapping should be done.

why is that?

...These cars do not respond well to half measures. Either build an all new engine and do EVERYTHING hi-po all at once, or leave it stock.

If you want some sound, delete the secondary cats and swap mufflers, but that is ALL you want to do.

All of these intake mods are a waste of time.
