Thank you for choosing IAG Performance. The IAG Billet
elbow is a direct replacement for the factory elbow on the
stock aluminum blow off valve (BOV). This installation
guides starts after you have removed the BOV from the
vehicle. Given the many different intercooler and chassis
set-ups that it can be configured with, we will not be
covering the steps to remove the BOV from the engine.
Once you have removed the BOV from your engine, please
follow the instructions below for an easy installation.
1. Using a #1 screwdriver, remove both of the screws
securing the elbow to the housing. Set the old elbow, o-
ring and screws aside.

2. Lightly coat the new o-ring with oil before installing on
the inner lip of the billet elbow. This is to keep the o-ring
from rolling up on the lip before you install it into the
housing. Install the billet elbow and align the holes.

3. Install and tighten with the new supplied screws.

Tech Tip
4. If you are using this elbow with a FMIC, you can rotate
the elbow 180° to aid in re-circulating the dump back into
the intake.
