The OEM inlet pipe is made of plastic and is prone to failure. Replace this flimsy piece with the newly designed turbo inlet from MST Performance. This inlet is constructed from CNC-machined billet 6061 aluminum and wire re-enforced multi-ply silicone. It is much more reliable under stock levels of boost, and can handle higher boost levels as well. After installation, you can expect improved turbo response, increased flow, and decreased turbo lag.
