The K-Tuned velocity coupler, crafted from reinforced 4-ply silicone, is a game-changer. It eliminates the step at the throttle body opening, straightening and accelerating intake airflow. This helps your engine breathe easier and perform better. Intake system design and airflow are crucial for maximum power. Similar to a velocity stack, this coupler boosts engine volumetric efficiency. Regular silicone couplers create a step that slows airflow and causes turbulence, but the K-Tuned coupler gets rid of that issue. Its taper increases intake air velocity. It fits most 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 a 3' diameter intake pipe. Applications include K20A, K20A2, K20A3, and K20Z1 throttle bodies.
Using the K-Tuned throttle body velocity coupler is straightforward. First, make sure your engine is off and cooled down. Remove the old intake coupler from the throttle body. Then, install the K-Tuned coupler, ensuring that the end custom - fitted to the OEM 62.5mm K - series throttle body (cable versions) is correctly attached to the throttle body, and the other end is connected to the 3' diameter intake pipe. When handling the coupler, be gentle to avoid damaging the reinforced 4 - ply silicone. As for maintenance, periodically check the coupler for any signs of wear, such as cracks or tears. You can clean it with a mild soap and water solution. Avoid using harsh chemicals that could damage the silicone. If you notice any significant damage, it's best to replace the coupler to keep your engine running smoothly.
