as far as not feeling vtech in a D16Y8 i have to argue.. I own a 99 Civic EX with two D16Y.. 1 being the stock engine with a injen cold intake with some other small goodies and then the one I just had bored and stroked and my 3rd engine is being shipped out which I am getting specs from people on this forum.. anyways to the point with a stock air box you won't feel vtech or hear yet with a short ram cold airtake you will hear it.. and it sounds nice! especially in 2nd and 3rd anyways on a stock engine with a short ram you will hear...
