We’ve got another awesome project in the works for the 8th-generation Honda Civic Si! Our recently released performance intake system received great feedback from customers, but it also identified an additional need for intake system components. We decided to develop a Civic Si induction hose made from silicone to replace the stock rubber unit.

If you follow our engineering blog you may have noticed some recent attention on the 8th-generation Civic Si. Well, we aren’t making a push for just this generation. We also want to dive into the 9th-generation and develop some unique new parts to improve this awesome car.
Our first project will be quite simple: to produce a Civic Si induction hose that replaces the stock rubber unit. This upgrade provides improved durability as well as pleasing aesthetics for those seeking some engine bay style. We have seen slight power increases with intake hoses developed in the past, so we will be … Continue Reading ››
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 … Continue Reading ››
Now that we had a functional prototype, it was time to perform some dyno testing to ensure that we were on target for producing a power-adding intake system. The dyno results would provide some base-line data so we could move forward with refining our intake design.
We quickly strapped the Si onto our Dynojet in preparation for our day of testing.

With a K-series power plant, 6-speed manual transmission, and a limited slip differential, the Si is a great choice as a fun commuter that can double as an autocross machine on the weekends. As with any performance vehicle, more power is always on the minds of enthusiasts. Mishimoto has been working to develop brand-new … Continue Reading ››
