The Honda Si Sport-Compact craze is back with a vengeance for the 10th gen civic, and Injen is here to make all your happy modding dreams come true! Whether going for a subtle black look, or an in-your-face wrinkle red designed to turn heads at car shows and car parks alike, Injen has your Si Induction system covered.  Injens SP Intake for the 2017+ Honda Civic Si 1.5L Turbo is designed to free up the restrictions that the factory induction box inherently has. Ask any enthusiast, any real Honda enthusiast or reviewer; they all say the same thing... "The Si needs more noise and excitement in the engine bay from factory." Thanks to Injens own in-house design and development team you can experience an impressive gain of over 20 horsepower and torque designed to fatten up the critical 'mid-band' power figures of the engine. Make your butt dyno and ears happy with the sound and thrill only an Injen SP cold air intake system can provide.

Since the harmonic-resonance of an intake system is a function of the length of the induction tube, having a Long-Tube system like this provides more torque lower in the RPM range where you'll use it most often in contrast to a short ram system which only provides peek benefits at the top of the rev range. What this means for you is more pull from the seat of your pants from stop-light to stop light, regardless of what the 'peek HP' gains are advertised. The Long-Tube design also amplifies lower engine note frequencies providing an even deeper more aggressive tone to your driving experience, turning heads as you drive from point to point.
