REMOVAL/INSTALL OF 1.4L TURBO AIR INTAKE MANIFOLD (615-380)
Buick 2019–13, Chevrolet 2019–12
General Tech Tips:
• Spare O-rings: New O-rings have been provided for your OEM fuel injectors (brown) and OEM MAP sensor
(blue). Replace O-rings carefully after parts are removed from the engine and prior to assembly of the new
manifold – take care not to cut sealing surfaces of the MAP sensor and fuel injectors when removing old
O-rings.
• Fuel Rail Installation: Make sure injectors are fully seated into the injector pockets by pushing down, directly
above each injector before securing the fuel rail. Utilize a tightening torque of approximately 5-7 Nm or until
the fuel rail is securely fastened to the intake manifold. DO NOT OVER TIGHTEN!
PLEASE WEAR
SAFETY GLASSES!

STEP 3: Clean cylinder head mounting surface to help ensure proper sealing when
installing your new manifold.
STEP 4: Slip the solenoid over the mounting feature on the underside of the manifold.
Once in place, use one of the M6 self-tapping screws to secure the solenoid to the
