2006-2011 Honda Civic Si to 3.5" K-Tuned Throttle body Velocity Coupler

2006-2011 Honda Civic Si to 3.5" K-Tuned Throttle body Velocity Coupler

Applications:

• K20A Throttle body
• K20A2 Throttle body
• K20A3 Throttle body 
• K20Z1 Throttle body 

The K-Tuned velocity coupler is made from reinforced 4-ply silicone. This unique part completely removes the step commonly found at the throttle body opening, which straightens and accelerates the intake airflow and in turn helps the engine breathe easier.

This will fit the most commonly used 3" intakes on the market. One end is custom fitted to the OEM 62.5mm K-series throttle body (cable versions) and the other end matches up to a 3" diameter intake pipe.
