Review on Injen Technology SP1431P Polished Intake by Ricardo Tlaxcalteca

If you need loud sound, look no further. This thing makes my TSX noticeably louder under acceleration and really roars when you rev it up to higher RPMs. I love it when I'm over 4000rpm, like it over 3200rpm, don't like it under (because it sounds louder but not sexy. Sort of like an ovary). There were some minor issues with some of the links staying in place (think it's a MAF sensor or something?). Over time, they fall off despite the presence of brackets. You just have to keep checking back to reattach them.
