    Builder Tips:
    • Most 13–18 charge pipes use 3.0"–3.5" OD tubing. Measure tube OD and match coupler ID before ordering.
    • Bead-roll tube ends for best clamp retention; T-bolts typically require snug, even torque—always follow the clamp manufacturer’s instructions.
    • Use aluminum for intercooler/intake (lightweight, easy to weld) and stainless for hot-side/exhaust durability.

    Frequently Asked Questions

    What size couplers do I need for my 2013–2018 Ram 6.7L?
    Many builds use 3.0"–3.5" OD tubing on charge pipes. Verify the outside diameter at the intercooler outlets and intake horn, then select matching ID couplers and T-bolts from our Silicone Couplers and T-Bolt Clamp listings.
    Why use V-bands instead of traditional flanges?
    V-bands are compact, serviceable, and seal evenly around 360°, which is ideal for turbo outlets and tight exhaust routing.
    Do I need to bead-roll aluminum tubes?
    Yes—bead-rolling greatly improves coupler retention under boost. See the Fabrication Components category for the CPP bead roller and materials.
    Which weld bungs are common for custom plumbing?
    -8AN and -10AN are popular for fuel/return and crankcase/vent lines. We stock -8AN and -10AN aluminum male bungs for clean installs.
