With a gutsy four-cylinder engine, a sporty chassis, and a starting price under $28,000, you’ll be racing to customize your very own 2022 Honda Civic Si!
The ever-reliable Honda Civic just got a lot more fun! The 2022 Honda Civic Si transforms the historic Civic line for a new generation. Boasting a performance-tuned chassis, a powerful four-cylinder engine, and plenty of add-ons and modifications, building a customized Honda Civic Si is a fun and surprisingly affordable way to step into a new, cool, and personalized ride.
There are many things you need to consider before customizing a 2022 Honda Civic Si. Fortunately, we've created a guide to building the car of your dreams at a price you can afford!

2022 Honda Civic customization options

The 2022 Honda Civic Si is built for performance and is priced for the everyday driver. The Civic Si offers a supremely sporty and stylish ride without sacrificing the reliability and economy for which the Civic line is famous. Coming in six colors ranging from sonic gray pearl to Aegean blue metallic, and with customizations ranging from chrome wheel locks to trunk trays, the Civic Si stands out from its sport compact competitors.
The 2022 Honda Civic Si only comes in two trim levels. The base trim starts at $27,300 while the Si HPT runs just a tad more expensive at $27,500
Both trims come standard with a six-speed manual transmission and front-wheel drive. The Civic Si does not have an automatic transmission option, nor can it be upgraded to all-wheel drive. 
Both the base trim and the HPT also come standard with the same 1.5-liter, 200-horsepower, four-cylinder engine, rated to 192 pounds of torque. The Civic Si is remarkably fuel-efficient, boasting gas mileage of 37 mpg highway and 27 mpg city
In addition, both trims’ exteriors come standard with 18-inch alloy wheels, full LED headlights, and dual chrome exhaust finishers. Their interiors sport Bose premium sound systems, automatic climate control, and leather-wrapped steering wheels.
In fact, the only real difference between the 2022 Honda Civic Si’s base and HPT trims is that the HPT comes with an additional set of summer tires. While this may seem a small difference, it’s well worth the extra $200, as drive tests have demonstrated that the Civic Si handles significantly better when equipped with seasonally-appropriate tires.

Honda Civic optional packages

Honda offers a wide array of optional packages, allowing drivers to further trick out their Civic Si. Ranging from the splash guard set of the All-Season Protection Packages to the emblems and spoilers of the HPD Package, you can customize your Civic to match your priorities and tastes. Here are some packages to check out:

You may further customize your Civic Si with additional add-ons such as illuminated door sill trim, cargo nets, black door visors, and an engine block heater.

How to customize your Civic to save money

While add-ons can be cool and fun, they will also significantly raise the price of your Honda Civic Si.
The 2022 Honda Civic Si starts at a very reasonable price of $27,300. However, with all available add-ons and packages, that price quickly climbs to $31,235.
All these extra add-ons and packages will not only cost you more money at the dealership, but they’ll also make insuring your Honda Civic Si more expensive. However, there are some customizations you can make to your Honda Civic Si that may save you money in the long run. Consider the following when customizing your Civic Si:
  • Cold air intake: Adding a cold air intake may improve your Civic Si’s fuel efficiency by as much as 3-5 mpg, saving you thousands of dollars over the life of your car.
  • Upgraded exhaust system: Optimizing your Civic Si’s exhaust system will increase fuel efficiency and have you
    saving money on gas
    .
  • Programmers/Tuners: A real win-win, a programmer/tuner will not only increase your Civic Si’s fuel efficiency, but it may also help you draw more power from your engine!

The best Honda Civic mods

While Honda offers a wide array of excellent customization options for the 2022 Civic Si, there are many other mods you can make on your own to further personalize your vehicle. Check out the following mods while customizing your 2022 Honda Civic Si:

Paint

Are the Civic Si’s six color options not enough for you? Go to your local body shop for a custom paint job that perfectly suits your style. Custom paint jobs range in price from $1,000 up to $4,500, so be sure to obtain quotes from multiple shops before you commit.

Floor mats

Keep your Civic Si’s interior clean by purchasing a set of laser-cut floor mats. You can buy floor mats specifically cut to fit your Civic Si for less than $200, making keeping your car free of dirt and debris easy and affordable.

Intake and exhaust ports

Enlarging your engine’s intake and exhaust ports generates more power by allowing the engine to draw extra air into and out of its cylinders, mixing it with more fuel. Porting your engine usually costs somewhere between $500 and $1,000.
Key Takeaway You can buy many cool add-ons and packages for your customized Civic, but the more you add, the more you’re likely to pay for car insurance.
