Do these need clamps or other hardware to seal?

These are pipe segments only—no internal seal or coupling hardware included. You'll need clamps, T-bolt clamps, or welding to join them to your existing piping and intercooler ports. Confirm your connection method before ordering.

Can I cut these down if I need a shorter run?

Yes. Aluminum cuts cleanly with a saw or band saw. Deburr the inside edge after cutting to prevent sharp edges from catching coolant flow.

What if I need different angles besides 90 degrees?

This kit is 90-degree elbows only. For 45-degree or 135-degree bends, you'll need to source those separately or have custom segments fabricated.
