After finding out the factory boost tube couplers threshold (roughly 34psi of boost) I made the decision to upgrade to PPE’s intercooler hot and cold side piping. I will say that most companies are all similar (WC Fab) that are producing one piece hot side kits. I personally wanted the one piece hot side pipe for piece of mind of less failure points. Install was easy enough and directions from PPE were actually helpful.
I pulled both fender liners to gain access. Disconnected both negative battery terminals. Removed my intake / filter assembly. Cold side first, pulled both sides of the metal clip to release the coupler from the intercooler, same for the other side at the “throttle body/blade”, disconnected the temperature sensor, and removed the factory cold side pipe. Transferred the sensor to the new 3.5” PPE cold side pipe and installed it using PPE’s new hardware.
For the hot side, I disconnected the 3 plugs on the ECM (make sure your battery’s are disconnected before doing so) as the plugs and wiring will be in the way. Loosened the factory T bolt clamps and removed the factory hot side piping out through the top. I fed the 3” PPE hot side pipe through the fender well right next to the ECU. This does take a few minutes to finagle it up, but is not difficult. Installed the new PPE couplers and hardware and reconnected the ECM plugs and battery cables. Re-installed the intake and filter, and started the truck.
I did a few brake boosts to ensure all my clamps were tight and the truck was building boost, then installed the fender liners. All in all this upgrade took me about an hour, and made a massive difference in how my truck builds boost and how responsive it is.
I’ve got quite a few more mods coming in from PPE, so stay on the lookout for posts. I will try and take more pictures and possibly videos of future installs.
First two pictures are of the failed factory coupler boot.
