Anyone know the official release dates of intakes/exhausts?

I see some people with a SRI(takeda intake). Will they ever make a CAI for our cars?

Will SRI or CAI improve gas mileage? If so, why, and how?

How about Exhausts? Will these improve gas mileage?

I'm aware of power gains, just unaware of MPG it will effect, someone shed someone please shed some light

 

My MPGs haven't improved (worsened actually) but that's my fault because I'm enjoying the extra pep and sound thanks to a heavier foot. I have the Takeda intake and Magnaflow axel-back. However, I will say this that so far with this latest tank of gas, 160 km/100 miles on it and a "normal foot", my MPGs are in the high 9L/100km (low 24 mpgs) which is best so far I've had on the same ~ 75% city/25% hwy breakdown.

Any other tested information about this?

 

just installed my takada intake on tuesday. Since topping off wednesday i'm currently sitting at 20 mpgs having driven this tank in S+ mode so far, and have been heavy on the pedal several times (see video for few examples). I usually get 16-18mpgs in S+ on a tank like this.

 

when majority of people install exhaust, MPG usually goes down due to enjoyment

 

Gotta agree with this lol installed my GReddy intake yesterday and ya it's over for the gas tank lol haha

 

Nice Pics, what shop did you go to ?????

 

on the 4th tank since i installed my takada and to be completely honest it seems my MPGs went down in ECO mode. I've tried twice to run on ECO mode and was barely got up to 19.5 gallons. However in sport + I could never get above 18 MPGs, and now with the intake I can get up to 21 MPGS in sport +.

 

fyi...previous gen fsport lower box will bot fit 3rd gen...i just tried but the ports dont align...so i drilled a 3" hole with a hole saw in the original.

will post more pics and review later

 

what i would love to see is exhaust with helmhotz resonator to control drone .... a la hks for z370

 

HKS has a system for is-f

I went to Dynamic Turbo...hit up Jay he has intakes in stock for our cars just tell him Jason sent you
