Review on 57 2519 3 FIPK Performance Intake System by Josh Sharp

The performance increase and audibility is excellent, but the installation is not the best. The PCV and IAC hose fittings on the main intake manifold are in the wrong place (at least on my 2004 Mustang GT). They're almost exactly where the oil filler cap is, where you can't push the cap in and remove it. I had to bend the heat shield significantly to lower the pipe to allow those fittings to be deep enough under the filler cap. Unfortunately, this only allowed me to use one (the longest) motor mount, but it's still solid. Aside from this unexpected (poor design), the rest of the install went fine.
