That's a GTT in the video. About 280bhp stock at the flywheel. 2.5 single turbo, as opposed to the 2.6 twin-turbo GTR. And rear wheel drive. I had the same (albeit older generation) motor in my Stagea. The figure in the video could well be power at the wheels? Would probably be about right. And yeah, cold air feed will make pretty much no difference at all on a Civic. Certainly nothing noticeable. Same with filters and stuff like that. Even on turbos these things only produce marginal gains at best, and even then, as pointed out, can do more harm than good in some cases. Shiny new parts though.....sometimes it's hard to resist
