Why a performance turbo inlet manifold?
stock LLY turbo inlet manifold / mouthpiece is noticeably restrictive
which contributes to higher inlet air, engine, and exhaust temperatures
than necessary. In order to make maximum power and operate at peak
efficiency, engines need to breath! When comparing this performance
inlet manifold to the stock part you will notice that the performance
part has a much smoother radius which is far more conducive to efficient
airflow. Additionally, the opening of our manifold where it meets the
turbo is substantially larger in diameter. Customers report faster turbo
spool times and increased throttle response when this part is
installed. A performance inlet manifold makes sense for trucks that have
larger performance exhaust systems since an engine cannot breath out
any more air than it breaths in!
interesting feature of this performance elbow is an internally threaded
CCV connection port. If your truck is used on the street, then the CCV
hose would connect to this port as normal. In racing applications the
CCV (closed crankcase ventilation) system may sometimes be re-routed
making this connection point unnecessary, in which case a plug is
included to close the port.
This performance elbow does NOT include a provision for the factory air resonator which can be removed.
the most part, installation is a very simple matter of removing the old
elbow and reversing the procedure to install and should be a proverbial
"snap" for anyone with basic mechanical skills - a few items should be
noted as follows
If installing the CCV plug for racing application only, do NOT
over-tighten which risks cracking the part. Just snug is sufficient.
Cracking due to over-tightening is NOT a warranty condition.
The factory CCV tube contains an inner support liner that is no longer
needed with this performance elbow and will need to be removed by
grasping it with pliers and firmly working it out.
A zip tie is included and is recommended to be used for tying the VGT
turbo actuator wiring so that it does not contact the turbocharger
housing or inlet manifold.
These tips are not intended as a substitute for factory service
information which should be read and followed including all safety
precautions which include wearing safety goggles throughout the entire
2004 owners must confirm that their truck is an LLY model. This will
NOT fit early 2004 LB7 models. LLY trucks have a "2" in the eighth VIN
