Helpful Notes

• Material choice: Aluminum is light and ideal for charge-air; 304 stainless excels for hot-side and durability.
• Beads & boots: Add a proper bead to all slip-fit joints (bead roller or HD clamp systems) to prevent boost leaks.
• V-band sizing: Match flange size and turbo family (HX35/HX40, S300, S400) before ordering.
• Support & clearance: Use isolators and adequate hanger/supports to prevent cracking on long runs.

Frequently Asked Questions

What pipe size works best for 12-valve intercooler plumbing?

Most 94–98 builds use 3.0" hot/cold-side piping. Larger turbos or high-flow cores may justify 3.5" where space allows.

Do I need V-bands or can I use band clamps?

V-bands provide precise, leak-free service and easy removal. Band/U-bolt clamps are cost-effective for slip joints—use beads to keep boots secure.

Aluminum or stainless for custom charge pipes?

Aluminum keeps weight down and transfers heat quickly; 304SS is stronger and preferred for hot-side or where abrasion is a concern.

How do I keep couplers from blowing off?

Use beaded ends (or bead roller), quality 5-ply silicone couplers, and constant-tension or HD clamps. HD union systems are available in our fabrication hardware assortment.

Can I buy universal intercooler cores and build my own?

Yes—see On3 race cores and related hardware. Measure carefully for height/width/pipe location before welding tanks.
