78-80 CB400a CB400t Carb Boot (Pair)

$29.99
Are the carb-to-airbox boots on your vintage Honda CB400 cracked, leaking, or completely missing? This is a common failure point on these bikes after decades of heat and age — but there’s now a clean, modern replacement designed to restore proper sealing and airflow.

These 3D-printed replacement carb boots are designed specifically for 1978–1980 Honda CB400A (Hondamatic) and CB400T models. They install between the carburetors and the factory airbox, restoring a proper seal while maintaining correct fitment and factory-style geometry.

Manufactured from durable black TPU, these boots provide the flexibility, resilience, and sealing performance that hardened OEM rubber can no longer deliver. The material is designed to flex without cracking, helping prevent vacuum leaks and inconsistent running caused by deteriorated originals.

This kit includes:

✅ (2) flexible TPU carburetor-to-airbox boots
✅ One boot per carburetor

Key features & benefits:

✅ Direct-fit replacement for 1978–1980 Honda CB400A and CB400T
✅ Flexible TPU construction replicates original rubber performance
✅ Restores proper airflow and sealing between carb and airbox
✅ Resistant to cracking, shrinking, and brittleness
✅ Ideal for restorations or reliable daily riders

Band clamps are not included — please reuse your original clamps or source replacements as needed.

Whether you’re reviving a barn find or keeping a vintage Honda on the road, these boots provide a simple, functional upgrade that solves a known reliability issue.

Professionally designed and tested by Incendiary Concepts LLC, focused on restoring factory function with modern materials and precise fitment.
