Description

EC 313FA CNC Filter Adapter – Fits Tillotson HL-334B


The EC 313FA Filter Adapter is engineered to securely mount a 2.5" ID air filter to your Tillotson HL-334B carburetor. Designed for racing classes where velocity stacks are not permitted, this adapter delivers a compliant, high-quality alternative without compromising fitment or durability.


CNC-machined from 6061-T6 billet aluminum, the 313FA ensures a precise, vibration-resistant fit and maintains consistent airflow through the intake system. While we recommend velocity stacks for unrestricted classes due to their airflow advantages, this adapter is the ideal solution where filter adapters are mandated.

Includes all necessary hardware for a clean, reliable installation.


Always consult your racing rulebook to confirm if a filter adapter is required or allowed before purchasing.
