Installation Instructions

IMPORTANT: Make sure the hose does not have any low points (sags or dips) where condensation or oily residue will collect and prevent free ventilation flow. This condition can cause the crankcase to become over-pressurized and result in oil leaks around your engine.
Secure the hose with supplied zip ties, and allow the hose to discharge freely into the open air.
6.Remove the rag from the turbo intake tube, and install the new
4” powder coated tube into the turbo intake tube. Re-install the air intake hose and stock air box lid (or filter element/cold air intake box, etc.).
CAUTION: Before tightening the clamps around your intake tube, etc., make sure it does not rub
against either
A – aluminum turbo outlet tube, OR
B – brake master cylinder.
Once you are finished, re-check the doghouse screws and all clamps for tightness.
O final recommendation. You should seriously consider removing and cleaning your charge air cooler (also referred to as the air-to-air cooler, or intercooler). The extent of oily residue contamination can be very extensive throughout your air intake system. These pictures reveal how the oily residue had made it all the way through this 2003 engine’s system (7.3L with 132,000 miles). Residue had accumulated in the lip of the hot side intercooler pipe where it connects to the spider, right before entering the air intake plenums and combustion chamber. You can even see the oil running down the spider’s adjoining connection nozzle.
To clean the intercooler, you remove it, drain it out into a bucket, mix a strong solution of Simple Green and pour it in, slosh around and let it soak, rinse thoroughly, and re- install.
