So, you've got yourself a 2018 Subaru WRX STI, huh? Awesome choice! These cars are beasts straight out of the factory, but let's be real, there's always room for improvement, right? Whether you're looking to boost performance, enhance the style, or just make your daily drives a bit more comfortable, there's a whole world of accessories out there waiting for you. Let's dive into some of the top 2018 Subaru WRX STI accessories that can take your ride to the next level.

Performance Enhancements

When it comes to performance, the 2018 Subaru WRX STI is already a solid performer, but with the right accessories, you can really unleash its full potential. Upgrading your exhaust system, for instance, is a popular modification. A cat-back or turbo-back exhaust system can significantly improve exhaust flow, leading to increased horsepower and torque. Plus, let's be honest, a deeper, more aggressive exhaust note just sounds plain awesome. Brands like Invidia, Cobb Tuning, and Nameless Performance offer great options for the STI.

Another key area to consider is the intake system. A cold air intake (CAI) can help your engine breathe easier by drawing in cooler air, which is denser and contains more oxygen. This results in better combustion and, consequently, more power. Just make sure you choose a reputable brand and consider whether you need a tune to optimize the performance gains. Companies like AEM and Perrin offer well-regarded intakes for the WRX STI.

Tuning is another crucial aspect of performance enhancement. The 2018 WRX STI's ECU (Engine Control Unit) can be remapped to optimize various parameters such as fuel delivery, ignition timing, and boost levels. A professional tune, whether through a Cobb Accessport or a custom dyno tune, can unlock significant power gains and improve overall drivability. However, always remember that tuning can affect your car's warranty, so weigh the pros and cons carefully.

Don't overlook the importance of suspension upgrades. Upgrading to aftermarket coilovers or lowering springs can improve handling and reduce body roll, making your STI feel more planted in corners. Brands like Bilstein, KW, and Tein offer a range of options to suit different driving styles and budgets. Paired with sway bars and strut tower braces, these upgrades can transform your STI into a true cornering machine. Finally, consider upgrading your intercooler. A larger, more efficient intercooler will help keep intake temperatures down, especially during spirited driving or on hot days. This prevents heat soak and ensures consistent performance. Mishimoto andProcess West offer great intercooler upgrades for the 2018 STI.

Aesthetic Upgrades

Looks matter, and the 2018 Subaru WRX STI is a great canvas for expressing your personal style. One of the easiest and most impactful visual modifications you can make is upgrading the wheels. A new set of aftermarket wheels can dramatically change the appearance of your car. Consider factors like size, offset, style, and weight. Popular brands include Enkei, Volk Racing, and Work Wheels. Pair your new wheels with a set of performance tires for improved grip and handling. A lip kit or body kit can add a more aggressive and sporty look to your STI. These kits typically include front and rear lips, side skirts, and sometimes a rear diffuser. Brands like Varis, Chargespeed, and APR Performance offer high-quality body kits designed specifically for the WRX STI.

Lighting upgrades are another great way to enhance the aesthetics of your car. Consider upgrading to LED headlights, taillights, and fog lights for a more modern and brighter look. You can also add aftermarket daytime running lights (DRLs) or sequential turn signals for a unique touch. Companies like Morimoto and Diode Dynamics offer a wide range of lighting upgrades for the WRX STI.

Interior accessories can also make a big difference in the overall look and feel of your car. Upgrading to aftermarket seats, such as those from Recaro or Bride, can provide better support and comfort, as well as a sportier appearance. A new shift knob, steering wheel, and floor mats can also add a touch of personalization to your interior. Don't forget about window tint. It not only enhances the look of your car but also provides privacy and reduces heat inside the cabin. Just be sure to check your local laws regarding window tint darkness. Lastly, consider adding a rear spoiler or wing. While the STI already comes with a rear wing, upgrading to a larger or more aggressive one can further enhance its sporty appearance. APR Performance and Seibon Carbon offer a variety of spoilers and wings for the WRX STI.

Comfort and Convenience

While performance and aesthetics are important, don't forget about comfort and convenience. After all, you'll likely be spending a lot of time in your STI, so it's worth making it a pleasant place to be. All-weather floor mats are a must-have, especially if you live in an area with rain or snow. They protect your carpets from dirt, mud, and water, and are easy to clean. Brands like WeatherTech and Husky Liners offer durable and custom-fit floor mats for the WRX STI.

Consider seat covers to protect your seats from wear and tear. They can also add a touch of style to your interior. Options range from basic cloth covers to premium leather or neoprene covers. A sunshade is essential for keeping your car cool in the summer. It also protects your dashboard from cracking and fading due to prolonged exposure to sunlight. Look for a custom-fit sunshade for the WRX STI for the best coverage.

A dashcam can provide peace of mind by recording your drives. It can be useful in the event of an accident or other incident. Many dashcams also offer features like GPS tracking and parking mode. A remote starter can be a lifesaver in cold weather. It allows you to start your car from inside your home or office, so it's nice and warm when you're ready to go. Be sure to choose a remote starter that's compatible with your STI's security system.

Protection and Maintenance

Protecting your investment is crucial, so consider these accessories to keep your 2018 Subaru WRX STI in top condition. A car cover is essential for protecting your car's paint from the elements, especially if you park outdoors. Look for a waterproof and breathable car cover that's designed specifically for the WRX STI. Mud flaps can help protect your car's paint from rocks, gravel, and other debris kicked up by the tires. They're especially useful if you live in an area with unpaved roads or harsh weather conditions. Rally Armor and RokBlokz offer durable and stylish mud flaps for the STI.

Paint protection film (PPF) is a transparent film that's applied to your car's paint to protect it from scratches, chips, and other damage. It's a worthwhile investment, especially for high-wear areas like the front bumper, hood, and side mirrors. A ceramic coating provides an extra layer of protection for your car's paint. It creates a hydrophobic surface that repels water and dirt, making it easier to wash and maintain your car's appearance. Plus, it adds a deep gloss to the paint.

Regular maintenance is key to keeping your STI running smoothly. Invest in a quality set of tools and fluids for performing basic maintenance tasks like oil changes, filter replacements, and brake pad replacements. A scan tool can be useful for diagnosing any issues with your car's engine or other systems. It allows you to read and clear diagnostic trouble codes (DTCs). Keeping your 2018 Subaru WRX STI in top condition requires the right accessories. By investing in performance enhancements, aesthetic upgrades, comfort and convenience features, and protection and maintenance items, you can ensure that your STI remains a joy to drive for years to come. So, go ahead and personalize your ride and make it truly your own!
