This pipe from FTP motorsports will not only improve flow over stock but also make a big improvement in the reliability column. 

The factory piping is made from plastic to reduce weight and manufacturing costs. While this is great for the production line and the sticker price, it doesn't hold up well as the engine ages or in the case of increased power.

Replacing the weak plastic stock part with a solid aluminum one like this will ensure proper functionality under higher levels of boost and eliminate wear caused by the heating and cooling of plastic pipes.

Features:

• Smooth bends for unobstructed flow
• Direct OEM replacement
• Larger than stock diameter for increased charge-air volume
• 3-Ply silicon couplers
