    Our last write-up for this Civic Si intake included our dyno testing results as well as some insight into our use of 3D printing for rapid prototyping. Since then, we've tweaked our design to provide flawless fitment and we've constructed a final prototype. The last box to check on our list is a final fitment verification and road testing. Our test vehicle owner will be putting some additional road miles on the car and will offer his opinion of the improved intake sound. Soon we will have a new addition to our line of Honda Civic Si parts!
