Different intake hose shape
 

I saw that aftermarket intake hoses are available in different shapes. Some, like Mishimoto, have the same shape of genuine, some, like Greddy, Perrin and R Magic in particolar, have different bendings and bigger volume. I think they act like a plenum chamber, and they say they improve throttle response.
What do you think?

I doubt they provide any noticeable difference. I have a Perrin intake that I got mainly to get rid of the sound tube and it had zero impact on how the car feels.

I have the Greddy, and I noticed an improvement in response, in particular at low revs, comparing to stock hose with closed sound tube.

I have the HKS and if it provided anything it was minimal.

Absolutely not placebo. I'm sensitive. Not everybody needs a turbo to feel the differences.

Ya OK

Must be lonely being smarter than everybody else.

The Mishimoto inlet tube did make a slight difference for me with throttle response.

Looks to be a repeatable slight improvement to performance —> https://www.ft86club.com/forums/show...1&postcount=13

You can feel 2hp ?

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

If you can feel a 2HP increase (with a tune!) you should be a professional driver!

Your throttle body opening remains the same. Your throttle plate doesn't all of a sudden open more because there is a different tube. You are not moving any more air through the engine because you have a different shaped tube.

Exactly how was tis "slight response" measured?
"I can feel it" in not an answer.

you have no idea how hard it is.

I did say slight, it’s not like it turns it into a Hellcat. I was sceptical about any performance gains and did it mainly to clean up the engine bay. I was pleasantly surprised after I took it for a drive afterwards. I’d say it feels more “peppy”, throttle response more immediate. Like the car had a coffee shot, lol. Bear in mind my car is a ‘13, so pre-facelift version, which I believe has the less efficient intake design.
