The 2017+ Honda Civic Si is a fantastic car right out of the factory. But for some of us, factory isn’t enough. We want more power and crave more performance. That, my friends, is where the exciting world of 2017+ Civic Si aftermarket parts comes into play. This isn’t about slapping a shiny new badge on your Si. It's about understanding what makes this car tick and enhancing it with parts. These 2017+ Civic SI replacement parts will help unleash its true potential.
Ready to transform your ride from awesome to exhilarating? This section is for you. I'll dive into spare parts that can seriously boost your 2017+ Civic Si’s performance, handling, and looks.
Everyone cares about getting that extra oomph from their Si's. While the turbocharged engine already packs a punch, a few key upgrades can push it to another level.
The stock intake on your 2017+ Civic Si is like making your engine breathe through a straw: it gets the job done, but that's it. A cold air intake is like swapping that straw for a milkshake. Your engine gets more cold air, which means more power potential. It is one of the best ways to add horsepower to a Honda Civic Si.
A good aftermarket exhaust isn't just about sound—although that throaty growl is a nice bonus. A high-flow exhaust system reduces backpressure, allowing exhaust gases to escape more freely. This equates to horsepower and torque gains, especially when paired with a good intake. And who doesn't love a good soundtrack when they’re tearing up the pavement?
Think of tuning as giving your Si's brain a serious upgrade. Aftermarket tuning options, like those from Ktuner, can optimize fuel and ignition maps. This unlocks more horsepower and torque from that 1.5L turbo. Always get your tuning done by a reputable source to ensure it's done right.
All the power in the world won't mean much if you can't put it down effectively or confidently carve those corners. That’s where suspension mods make all the difference for your 2017+ Civic Si.
A lower center of gravity equals a more stable ride and improves your Si's overall handling dynamics. Lowering springs give you a subtle drop while maintaining a comfortable ride. Coilovers allow you to fine-tune ride height, and often, damping, for maximum control.
Body roll? No thanks. Aftermarket sway bars, often referred to as anti-roll bars, help minimize body roll during hard cornering, giving you that planted feel. Strut tower braces, both front and rear, stiffen up the chassis, improving responsiveness and making those quick direction changes much smoother.
Now it’s time to inject a dose of your personality into your ride. This isn't just about looks; it's about expressing yourself and showing that your Civic Si is unique. From sleek aero kits that enhance the already sporty lines to eye-catching headlights and taillights, the possibilities are endless. Upgrading your Civic Si's exterior with aftermarket parts allows you to customize its appearance with things such as a new shift knob or some sleek side marker lights. Adding some spark plugs will also add a nice touch.
Upgrading the brakes is just as essential as increasing power. Good brakes inspire confidence, especially when you're pushing your car's limits.
Upgrading to performance brake pads can provide a firmer pedal feel and improved stopping power. There are many options available, with some focusing on street performance for everyday driving and others designed explicitly for track use, where heat dissipation becomes even more critical. Whether you’re hitting the track or navigating city streets, high-performance brake pads can significantly improve your stopping distance and pedal feel. Upgrading your rear motor mount can also drastically improve your braking performance.
Performance brake rotors are designed to handle higher temperatures without warping. This is especially important during spirited driving or track days. With improved cooling and stronger construction, upgrading your rotors ensures they can keep up with your spirited driving style and help avoid brake fade when you need it most. They're a worthy upgrade to consider alongside those grippy pads for balanced braking performance.
We explored several paths to upgrade your 2017+ Civic SI with aftermarket parts. The journey of modifying your car is an adventure that allows you to mold your Si into an extension of your driving style and preferences.
