Ok so when I put this spacer in, immediate effects I noticed where the pull and the throttle response, both of which increased slightly, but still noticeably. I also noticed my engine idle at a lower rpm. As far as sound goes, the spacer doesnt make a difference, but some say it whistles with an aftermarket intake. Installation is easy for someone who has worked in their engine bay before, and still fair for those who havent. Overall, gains are small but for the money it's not a bad mod.
