I did little more research and finally found an independent dyno for the Takeda Intake for a 2008 Civic Si. The members on the Honda-tech forum were wondering what I was wondering how the intake for their car can possible produce even close to 17whp claimed by Takeda. Well the independent dyno showed an increase of 12whp on a 4cyl! Not the claimed 17whp but damn if the Takeda can produce an additional 12whp on a 4cyl with a single intake then the Takeda for the 370z should be able to get at least 12whp.

I know these are completely different cars but the 370z has two intakes and the dyno done on the Civic was on a really hot day. Dyno showing shop temps of 115F. So my concern about these things getting heat soaked and not producing power is not as much of a concern for me.
I went to your website to purchase the intake however there is a place to enter a coupon number. Is there a coupon number for this part? Or is the 349.00 the sale price?
