    5.0 out of 5 stars Perfect upgrade
    Reviewed in the United States on February 10, 2016
    I have a 2006 Acura TL and upgraded the intake manifold from a 3.7l zdx and throttle body. Came across a couple of diy's and decided this was the intake pipe isn't wanted. There is enough material left over for me to make a different set up. I wish I could have just bought the piece i needed. It was a very snugly fit for a 4in pipe and did notice after a 30 minute drive, the pipe is cooler compared to a aluminum pipe. Ending up spending about $170 with airaid, 4x7 in aem filter, and coupler.
