AFE Charge Pipes & Turbo Inlets for BMW 4 Series F32 (2014+)

Clear BMW chassis

Please ensure your correct model is selected

The factory BMW charge pipes are prone to cracking, as they are made from brittle plastic. Here at Turner, we sell several brands of replacement charge pipes that are typically made from cast aluminum. We recommend upgrading to hard charge pipes even on stock forced induction vehicles to avoid cracking - we've seen cracking occur on high mileage cars running stock power just as frequently as we do with high horsepower builds.

Perfect Fit:
Includes stainless steel clamps for a leak-free seal and heavy-duty 5-Ply reinforced silicone coupling for strength.

Mandrel-bent Tubing:
Constructed of 2-1/2" to 2-3/4" mandrel-bent aluminum tubing and powder-coated textured-red for heat and corrosion resistance. The smooth transition mandrel bends decrease turbulence which increases horsepower and torque. The high-temp wrinkle-black powder-coating insulates the tube from engine heat and protects the tube from corrosion.

aFe Badging:
Unique aluminum laser-cut aFe Power logo plate is welded-on for an aggressive style.

Also Fits:

On turbocharged motors, the intake piping is put under constant pressure while the engine is running, and has to hold that pressure without leaking. Unfortunately the smallest amount of damage or defect on the intake hoses and the pressure can cause a leak, leaving you without proper boost pressure.  Replace your leaking pressure pipe and stop loosing boost.
