Bear in mind my car is a ‘13, so pre-facelift version, which I believe has the less efficient intake design.

I don't deny these things make a difference, I am just skeptical as the claims people make are often overstated. I have the Perrin inlet tube on my car and don't really notice anything. I bought it just to declutter the engine bay of the sound tube after I went back to a stock airbox.

I'd also like to see the dyno, for, reasons. Curious if it is 2hp across, or just up top in higher RPM.

Some of the numbers from their site: https://www.mishimoto.com/engineerin...nt-completion/

HP, as a Dyno sheet, are measured only at WOT. Response feeling is a different thing. So it's possible to feel the difference. Anyway, with my previous car I felt a 0.5 kgm difference, later confirm by Dyno. @NoHaveMSG, if you'll cover my expenses I can try the professional driver career.

Guys remember, is not about the shape and size of the hose. Is about how you.....wait. Oh we're talking about cars. Carry on.

All companies will claim the same, because they need to sell their stuff. Having the same exact design as your competition warrants issues, legal ones. As a mod by itself, it may smooth out some rough edges on the curve, and the initial "responsiveness" is just the car adjusting itself for the first 50 miles.

When added as a whole with other mods, the results are better.

Which brings me back to my initial point, is not about the size of the hose, is how you use it along other things.

This ^
Changing the tube does nothing measurable. Changing the tube and tuning for it may make a tiny difference but then it begs the questions:
Was it the tube or the tune that made the improvement?
If you did the same tune with the stock parts would you have had the same results?
Are any improvements actually stackable?

If you are that sensitive, you should be able to fund it yourself testing parts. .5kgm is what, 3.6lb-ft. I'd say that is about on the cusp of noticeable for my butt dyno in a car.

When I was NA I made 207-8whp and 165trq (I think was numbers? was in 2017) Car felt amazing and wish I kept it this way before went turbo. But I think to get anything out of an intake need a tune. My mods are below when I dyno at that. I will try to find copy of dyno and post here.

I had P&L headers
Perring OP and P&L FP
Perrin 3" CBE
E85
AEM ETI (discontinued now) intake (When dyno before mods it was 2-3whp over stock) - (I have still have it if anyone wants it)
HKS Big snorkel (I also dont have a grill and have it cut out and open)
CF driversahft
fluidampner pulley
Full blow radiator
Full blown oil cooler

You want some real gains?
Next oil change use Royal Purple. Guaranteed 3 hp increase.
