I have a 2007 runner with the 4.7, I installed dual exhaust with flowmaster 50 series, I am thinking I now need more air and was looking at the K&N cold air 60 series, but got scared when some of the reviews said it decreases fuel economy and some even say it makes it run ruff because of the computer, can someone help me decide if this is something I need or would i regret it?..thanks in advance...Bobby
