Lingenfelter L650172012 Lingenfelter Camaro ZL1 Air Intake Duct 2012 v1.1 - Manual (Page 3)

Page
Thank you for purchasing the Lingenfelter Performance Engineering (LPE) Air Intake Duct Kit
for the ZL1 Camaro. This kit is designed to be installed in vehicles that will retain the Original
Equipment Manufacturer (OEM) airbox. Aftermarket supercharger pulleys and dampers increase the
supercharger speed and airflow, resulting in increased inlet pressure drop that can cause the factory
rubber inlet duct to get sucked shut under high RPM use. For this reason Lingenfelter Performance
Engineering has designed a replacement air intake system to resolve these potential problems.
Read the entire instruction manual before beginning installation. Many of the stock parts will
be used in reassembly.
When referencing the side of the vehicle, the driver side of the vehicle is considered the left
side and the passenger side of the vehicle is considered the right side of the vehicle.
Torque value warning - the torque values for the fasteners are provided in metric (Nm) and
then imperial units. For the imperial units some are referenced in lb-ft and others in lb-in. Make
sure you notice the difference and set your torque wrench correctly.
2.
1. Open the hood. If you have been driving
your vehicle, allow a couple hours for the engine
to cool down before beginning installation.
2. By pressing the retaining tab, disconnect
the Positive Crankcase Ventilation (PCV)
connector that connects the air intake tube to the
driver-side valve cover.
