2014 Nissan Altima Accessories

The 2014 Nissan Altima, a mid-size sedan known for its fuel efficiency and comfortable ride, offers a wide range of accessory options. Whether you're looking to improve its performance, enhance its aesthetics, or increase its practicality, this article will guide you through some of the most common and effective accessories available for your Altima.

Performance Accessories

For those interested in boosting the Altima's performance, a few key areas can be addressed. Keep in mind that modifications can sometimes affect your warranty, so always check with your dealer beforehand.

Air Intake Systems

An aftermarket air intake system, such as a cold air intake (CAI) or short ram intake (SRI), replaces the factory air box and filter. The stock intake is often restrictive to reduce noise and meet emissions standards. A CAI typically draws air from outside the engine bay, providing cooler, denser air to the engine, potentially increasing horsepower and torque. An SRI, on the other hand, sits within the engine bay and is easier to install, but may draw in slightly warmer air.

Installation Considerations: Installing an air intake system is typically a straightforward process, often involving removing the existing air box, disconnecting the mass airflow sensor (MAF sensor), and installing the new intake with provided hardware. Be sure to properly connect the MAF sensor to ensure accurate readings and prevent the check engine light from illuminating. Also, check your local emissions regulations to ensure compliance. Some CAIs may not be CARB (California Air Resources Board) legal in certain states.

Technical Terms: Mass Airflow Sensor (MAF): A sensor that measures the amount of air entering the engine. The ECU (Engine Control Unit) uses this information to calculate the correct air/fuel mixture.

Exhaust Systems

Upgrading the exhaust system can improve exhaust flow, reducing backpressure and potentially unlocking additional horsepower. Cat-back systems replace the exhaust piping from the catalytic converter to the muffler, while axle-back systems only replace the muffler. Full exhaust systems replace everything from the exhaust manifold. A cat-back system is a popular choice for Altimas, as it offers a good balance of performance and cost.

Installation Considerations: Exhaust system installations can be more involved than air intake installs, often requiring lifting the vehicle and using specialized tools such as a torque wrench. Ensure you use proper safety precautions, including wearing safety glasses and gloves. Pay close attention to the exhaust manifold bolts, as they can be difficult to remove due to rust and corrosion. Applying penetrating oil can help loosen them. When installing the new exhaust system, use new gaskets and tighten all bolts to the manufacturer's specified torque.

Technical Terms: Catalytic Converter: A device in the exhaust system that reduces harmful emissions. Backpressure: The resistance to the flow of exhaust gases in the exhaust system.

ECU Tuning

While not a direct 'accessory', a custom ECU tune can optimize engine performance by adjusting parameters such as fuel delivery, ignition timing, and boost pressure (if applicable; unlikely on a stock Altima). This often requires professional services from a tuning shop that utilizes software such as UpRev or EcuTek. Tuning will typically yield the most gains when combined with other performance modifications like an intake and exhaust.

Considerations: ECU tuning can void your powertrain warranty, so proceed with caution. A poorly executed tune can also damage your engine. Always use a reputable tuner with experience tuning Nissan vehicles. A Dyno tune ensures the best and safest calibration.

Aesthetic Accessories

There are numerous ways to customize the look of your 2014 Altima. Here are a few popular options:

Wheels and Tires

Upgrading the wheels and tires is a common way to improve both the appearance and handling of your Altima. Consider factors like wheel diameter, width, offset, and tire size. Using larger wheels can improve aesthetics, while wider tires can provide better grip. Be sure to choose wheels and tires that are compatible with your vehicle and do not cause rubbing or interference with suspension components.

Installation Considerations: Wheel and tire installation is relatively straightforward, requiring only basic hand tools and a jack. However, it's crucial to use the correct lug nut torque specification to ensure the wheels are properly secured. Overtightening can damage the wheel studs, while undertightening can cause the wheels to come loose. It's also advisable to get a wheel alignment after installing new wheels and tires to ensure proper handling and tire wear.

Technical Terms: Offset: The distance between the wheel's mounting surface and its center line. Lug Nut Torque: The specific amount of force that should be applied when tightening lug nuts, measured in foot-pounds (ft-lbs) or Newton-meters (Nm).

Body Kits and Spoilers

Body kits and spoilers can significantly alter the appearance of your Altima. Body kits typically include front and rear bumpers, side skirts, and sometimes a hood. Spoilers are mounted on the trunk lid or roof and can improve aerodynamics at higher speeds.

Installation Considerations: Body kit installations can be complex and may require professional installation. This typically involves removing the existing bumpers and side skirts, prepping the new body kit components, and painting them to match the vehicle's color. Proper fitment is crucial to ensure a seamless integration. Spoilers are generally easier to install, often attaching with adhesive tape and/or screws. Ensure the surface is clean and properly prepped before installation.

Lighting Upgrades

Upgrading the headlights and taillights can improve both the appearance and safety of your Altima. Options include LED headlights, HID (High-Intensity Discharge) headlights, and aftermarket taillight assemblies. LED headlights offer brighter and more energy-efficient lighting compared to halogen bulbs, while HID headlights provide even greater light output. Aftermarket taillight assemblies can add a unique and customized look.

Installation Considerations: Headlight and taillight installations can vary depending on the specific components. Some replacements are plug-and-play, while others may require wiring modifications. When installing HID headlights, be sure to use a proper wiring harness and ballast to prevent damage to the vehicle's electrical system. Also, adjust the headlight aim after installation to ensure proper visibility and avoid blinding other drivers. Illegal headlight tints may make you a target for law enforcement.

Technical Terms: Ballast: An electrical component used to regulate the voltage and current to an HID bulb. Plug-and-Play: An accessory that can be installed without any modifications to the vehicle's wiring.

Practical Accessories

Beyond performance and aesthetics, several accessories can enhance the practicality and usability of your 2014 Altima.

Floor Mats and Cargo Liners

All-weather floor mats and cargo liners can protect the interior of your Altima from dirt, mud, and spills. These accessories are particularly useful if you live in an area with harsh weather conditions or frequently transport cargo. Look for mats and liners that are specifically designed for the 2014 Altima to ensure a proper fit.

Remote Start Systems

A remote start system allows you to start your Altima from a distance, allowing the engine to warm up in cold weather or cool down in hot weather. Many aftermarket remote start systems are available, offering features such as keyless entry, alarm systems, and smartphone integration.

Installation Considerations: Remote start system installations can be complex and typically require professional installation. This often involves tapping into the vehicle's wiring harness and programming the system to communicate with the car's computer. Ensure the installer is experienced in working with Nissan vehicles.

Backup Cameras

If your 2014 Altima doesn't already have a backup camera, adding one can significantly improve safety and convenience. Backup cameras provide a view of the area behind the vehicle, helping you avoid obstacles and park more easily. Aftermarket backup camera systems typically include a camera that mounts on the rear of the vehicle and a display screen that can be mounted on the dashboard or integrated into the rearview mirror.

Installation Considerations: Backup camera installations require routing wiring from the rear of the vehicle to the front, which can be time-consuming. Some systems require tapping into the reverse light circuit to activate the camera when the vehicle is in reverse. Professional installation is recommended for those unfamiliar with automotive wiring.

Important Note: Before installing any accessories, always research their compatibility with your specific 2014 Nissan Altima trim level and engine. Also, consult with a qualified mechanic or installer if you're unsure about any aspect of the installation process. Always prioritize safety and follow the manufacturer's instructions carefully.
