90mm 4 bolt C5 corvette throttle body
L270010197
Thank you for purchasing the Lingenfelter Performance Engineering (LPE) LS1/LS6 throttle
body coolant bypass kit. This kit is designed for use on any vehicle with an Original
Equipment Manufacturer (OEM) LS1 or LS6 throttle body. This kit reroutes the engine coolant
away from the throttle body, reducing the temperature of the air flowing through the air intake.
Read the entire instruction manual before beginning installation. Some stock parts will be
used in reassembly.
This kit is required for the installation of the LPE 90mm 4 bolt C5 Corvette throttle body (PN:
L270010197).
In designing the LS1/LS6 throttle body, GM chose to run the engine coolant through the
throttle body in order to reduce the chance of the throttle body icing over in extremely cold
weather. If the vehicle might be driven in temperatures approaching 32 degrees Fahrenheit or
below, it may be necessary to keep the engine coolant running through the throttle body until
the temperature of the operating environment increases.
