​Understanding the Infiniti G37 and the Role of Accessories​

The Infiniti G37, produced from 2007 to 2015, stands out for its powerful V6 engine, rear-wheel or all-wheel drive options, and refined design. As a used or classic vehicle today, it remains a favorite among enthusiasts and daily drivers alike. Accessories serve to modify, protect, or augment the car’s existing features. They are not merely cosmetic; practical accessories can enhance safety, increase storage, improve fuel efficiency, or prevent wear and tear. Before purchasing, assess your specific goals: are you seeking better performance, added convenience, or visual customization? Knowing this helps narrow down choices and avoid wasteful spending. Additionally, always ensure compatibility with your G37 model year and trim, as variations exist between coupe, sedan, and convertible versions.

​1. Performance Accessories for Enhanced Driving Dynamics​

Performance accessories aim to boost the G37’s engine output, handling, braking, and overall driving feel. These are ideal for owners who prioritize speed, responsiveness, or track use. Focus on reputable brands to maintain reliability.

• ​Cold Air Intake Systems:​​ A cold air intake replaces the factory airbox to allow more airflow into the engine, potentially increasing horsepower and throttle response. It often adds an aggressive sound during acceleration. Popular options include kits from ​Stillen​ or ​K&N. Installation is moderately simple, but ensure the system includes proper shielding to prevent heat soak.
• ​Cat-Back Exhaust Systems:​​ Upgrading the exhaust from the catalytic converter back enhances exhaust flow, reduces backpressure, and can add power while delivering a deeper, sportier exhaust note. Brands like ​ARK Performance​ or ​Invidia​ offer durable stainless-steel systems. Consider noise levels; some systems are loud, which may not suit daily driving.
• ​Suspension Upgrades:​​ Improving suspension components sharpens handling and reduces body roll. Key items include:
  • ​Coilover Kits:​​ Adjustable coilovers from ​BC Racing​ or ​Tein​ allow you to lower ride height and fine-tune damping for street or track use.
  • ​Sway Bars:​​ Thicker sway bars from ​Hotchkis​ or ​Whiteline​ minimize lean in corners, improving stability.
  • Installation often requires professional help due to alignment needs.
• ​Brake Upgrades:​​ For repeated hard braking, consider:
  • ​Performance Brake Pads:​​ Brands like ​Hawk​ or ​EBC​ offer pads with better bite and fade resistance.
  • ​Slotted Rotors:​​ These help dissipate heat and reduce brake fade, available from ​StopTech​ or ​DBA.
  • Stainless-steel brake lines can also improve pedal feel.
• ​Engine Tuning Devices:​​ A tuning device or ECU reflash from ​UpRev​ or ​Cobb​ can optimize air-fuel ratios and ignition timing, unlocking power gains when combined with other mods. This is a more advanced accessory best handled by specialists.

​2. Exterior Accessories for Style and Protection​

Exterior accessories modify the G37’s appearance or shield it from environmental damage. They range from subtle additions to dramatic changes.

• ​Body Kits and Aero Parts:​​ These include front lips, side skirts, rear diffusers, and spoilers. They can enhance aerodynamics and give a aggressive look. Brands like ​IPL​ (Infiniti Performance Line) or ​Stillen​ offer OEM-style parts. Ensure fitment is precise to avoid gaps or installation issues.
• ​Wheels and Tires:​​ Upgrading wheels reduces unsprung weight and improves looks. Choose sizes that match G37 specifications—common upgrades are 19-inch or 20-inch wheels. Pair with high-performance tires from ​Michelin Pilot Sport​ or ​Continental ExtremeContact​ for better grip. Always recalibrate the tire pressure monitoring system (TPMS) after changes.
• ​Lighting Upgrades:​​ Improved lighting increases visibility and style.
  • ​LED or HID Conversion Kits:​​ Replace halogen bulbs with brighter LED or HID bulbs for headlights or fog lights. Ensure they are properly aligned to avoid blinding other drivers.
  • ​Smoked or Clear Lens Covers:​​ These alter the look of tail lights or side markers, but check local regulations for legality.
• ​Protective Films and Coatings:​​ To preserve paint, consider:
  • ​Paint Protection Film (PPF):​​ A clear film applied to the hood, bumper, and fenders to prevent rock chips and scratches.
  • ​Ceramic Coating:​​ A chemical layer that adds gloss and repels water, dirt, and UV rays, making cleaning easier.
• ​Window Tints:​​ Tinting windows reduces heat, glare, and UV exposure, enhancing privacy. Use high-quality ceramic tints for best heat rejection, and adhere to local laws regarding darkness levels.
• ​Grille Upgrades:​​ A custom grille, such as a mesh-style grille, can refresh the front-end appearance. Installation typically involves removing the bumper.

​3. Interior Accessories for Comfort and Convenience​

Interior accessories make the cabin more comfortable, organized, or technologically advanced. The G37’s interior is well-appointed, but additions can address limitations.

• ​Seat Covers and Floor Mats:​​ Protect original upholstery with custom-fit seat covers from ​Covercraft​ or ​Wet Okole. All-weather floor mats like ​WeatherTech​ or ​Husky Liners​ trap dirt, water, and debris, keeping carpets clean.
• ​Steering Wheel Upgrades:​​ A leather-wrapped or perforated steering wheel cover improves grip, or consider a custom steering wheel with Alcantara for a sportier feel. Some owners opt for a quick-release steering wheel for modified builds.
• ​Audio and Infotainment Systems:​​ Upgrade the factory stereo for better sound.
  • ​Head Unit Replacements:​​ Aftermarket units from ​Pioneer​ or ​Kenwood​ with Apple CarPlay and Android Auto integrate modern connectivity. Use a dash kit specifically for the G37 to ensure a seamless fit.
  • ​Speakers and Amplifiers:​​ Replace factory speakers with higher-quality components, and add a subwoofer for bass. Sound deadening materials can reduce road noise.
• ​Storage and Organizers:​​ Maximize cabin space with:
  • ​Center Console Organizers:​​ Trays or dividers to sort small items.
  • ​Trunk Organizers:​​ Cargo nets, bins, or collapsible boxes to secure groceries or tools.
• ​Pedal Covers:​​ Aluminum or rubber pedal covers provide better foot grip and a sporty look. They are easy to install but require secure fastening.
• ​Dash Cameras:​​ A dash cam records driving footage, useful for insurance claims or security. Models like ​Vantrue​ or ​Garmin​ offer loop recording and GPS. Hardwire kits allow permanent installation without dangling wires.

​4. Practical and Functional Accessories for Daily Use​

These accessories address everyday utility, safety, and maintenance needs without major modifications.

• ​Performance Gauges:​​ Monitor engine parameters with gauges for boost, oil temperature, or AFR (air-fuel ratio). Pod mounts that fit the A-pillar or dashboard are available. This is crucial if you have performance mods to ensure everything runs smoothly.
• ​Phone Mounts and Chargers:​​ A sturdy phone mount, such as a vent or dashboard mount, keeps your device accessible for navigation. Pair with a fast-charger plugged into the 12V socket or USB port.
• ​Vehicle Security Systems:​​ Enhance theft protection with:
  • ​Alarm Systems:​​ Aftermarket alarms with motion sensors or shock sensors.
  • ​GPS Trackers:​​ Devices that allow you to locate your car via smartphone if stolen.
• ​Roof Racks and Carriers:​​ For additional cargo, install roof racks from ​Thule​ or ​Yakima​ specifically designed for the G37. They are useful for carrying bikes, skis, or luggage, but note they may affect fuel efficiency and noise.
• ​Engine Bay Accessories:​​ Simple additions like a ​strut tower brace​ can slightly stiffen the chassis, and ​coolant or oil catch cans​ help maintain engine cleanliness by trapping blow-by gases.
• ​Cleaning and Maintenance Kits:​​ Keep your G37 in top shape with microfiber towels, quality car soap, and interior cleaners. A ​portable air compressor​ for tire inflation is also a handy tool.

​5. Buying Guide: How to Choose the Right Accessories​

Selecting accessories requires careful thought to avoid poor fits or wasted money. Follow these steps:

• ​Define Your Budget and Priorities:​​ Determine how much you want to spend and whether you value performance, looks, or comfort most. Start with essential items like floor mats or a dash cam before moving to expensive mods.
• ​Research Compatibility:​​ Always verify that an accessory fits your specific G37 model year, body style, and engine type. Check product descriptions, reviews, and forums for confirmation.
• ​Choose Reputable Brands:​​ Stick with established brands known for quality, such as ​Stillen, K&N, WeatherTech, or Pioneer. They often provide better warranties and customer support.

• ​Consider Installation Complexity:​​ Assess your mechanical skills. Some accessories, like floor mats, are plug-and-play, while others, like exhaust systems, may require professional installation. Factor in labor costs if needed.
• ​Check Legal and Warranty Implications:​​ Modifications like window tints or exhaust noise may be regulated by local laws. Also, aftermarket parts can void parts of your vehicle’s warranty; consult your warranty terms beforehand.

​6. Installation and Maintenance Tips for Longevity​

Proper installation ensures accessories function correctly and last long. Here are key pointers:

• ​Use the Right Tools:​​ Have a basic toolkit including sockets, wrenches, screwdrivers, and trim removal tools. For electrical work, a multimeter and wire connectors are useful.
• ​Follow Instructions Carefully:​​ Read the manufacturer’s installation guide thoroughly before starting. Watch video tutorials specific to the G37 if available.
• ​Take Safety Precautions:​​ Disconnect the battery when working on electrical components. Use jack stands if lifting the car, never rely solely on a jack.
• ​Test After Installation:​​ After installing any accessory, test it immediately in a safe environment. For performance parts, consider a professional tune-up to optimize settings.
• ​Maintain Regularly:​​ Clean and inspect accessories periodically. For example, check cold air intake filters for debris, or ensure protective films are not peeling. This prevents damage to the accessory or your vehicle.
