The Infiniti G35 remains a legendary platform for automotive enthusiasts, offering a perfect blend of luxury and raw potential from its celebrated VQ35DE or VQ35HR engine. Whether you own the sleek coupe or the versatile sedan, the aftermarket support for this vehicle is vast, allowing owners to tailor their driving experience to their specific needs. By selecting the right Infiniti G35 performance parts, you can improve throttle response, increase horsepower, and sharpen the handling characteristics of this iconic Japanese rear-wheel-drive machine.
Optimizing Airflow with Intake and Exhaust Upgrades
One of the first steps in any build involves improving how the engine breathes. The stock airbox is designed for silence and comfort, but it often restricts the high-RPM flow that the VQ engine craves. Installing a high-quality cold air intake is one of the most popular Infiniti G35 performance parts because it provides a noticeable increase in induction sound and a modest bump in power.
To complement the intake, a performance exhaust system is essential. High-flow catalytic converters or test pipes, combined with a cat-back exhaust, allow spent gases to exit the engine more efficiently. This reduction in backpressure not only increases horsepower but also unlocks the signature VQ growl that many enthusiasts love. Consider a dual-exit system for maximum flow and a more aggressive aesthetic on the rear bumper.
Plenum Spacers: A Must-Have Modification
Specifically for the VQ35DE engines found in earlier G35 models, the intake plenum design is somewhat flawed, starving the front two cylinders of air. A plenum spacer is one of the most cost-effective Infiniti G35 performance parts available. By increasing the volume of the plenum, you ensure more even air distribution, resulting in gains across the entire power band, particularly in the mid-range where you feel it most during daily driving.
Sharpening Handling with Suspension Tuning
The G35 shares its chassis with the Nissan 350Z, meaning it has a fantastic foundation for handling. However, the factory suspension is often tuned for a softer, more luxurious ride. Upgrading to adjustable coilovers allows you to lower the center of gravity and fine-tune your damping settings for either the street or the track. This is a critical category of Infiniti G35 performance parts for those who want to eliminate body roll and improve cornering speeds.
Beyond coilovers, you should consider the following suspension components:
- Sway Bars: Upgraded front and rear sway bars significantly reduce body lean during hard cornering without sacrificing ride quality.
- Strut Tower Braces: These reinforce the chassis, providing more predictable steering input and reducing flex.
- Adjustable Control Arms: When lowering your G35, these are necessary to correct camber and toe settings, ensuring your tires wear evenly and maintain a proper contact patch.
Enhancing Braking Power and Reliability
With more speed comes the need for better stopping power. If your G35 didn’t come equipped with the factory Brembo package, upgrading your braking system is a wise investment. High-performance brake pads and slotted or drilled rotors can help dissipate heat more effectively, preventing brake fade during spirited driving sessions.
For those taking their car to the track, stainless steel braided brake lines are essential Infiniti G35 performance parts. They replace the factory rubber lines, which can expand under pressure, leading to a spongy pedal feel. Stainless lines provide a firmer, more consistent pedal response, giving you more confidence when diving into a corner.
Drivetrain Upgrades for Better Power Delivery
Getting power to the ground is just as important as making it. If you have a manual transmission G35, a lightweight flywheel and an upgraded clutch can transform the driving experience. A lighter flywheel allows the engine to rev more freely, making rev-matching and downshifting much more rewarding. For automatic owners, a specialized transmission cooler can help protect the gearbox from heat soak during aggressive driving.
The Role of Limited Slip Differentials
Many base model G35s came with an open differential, which can lead to “one-tire fire” scenarios when accelerating out of a turn. Swapping to a mechanical limited-slip differential (LSD) is one of the most impactful Infiniti G35 performance parts you can install. An LSD ensures that power is distributed to both rear wheels, providing significantly better traction and more predictable handling when pushing the car to its limits.
Tuning and Electronics: Bringing It All Together
Once you have installed several bolt-on Infiniti G35 performance parts, the factory ECU (Engine Control Unit) may not be able to optimize the new airflow and fuel requirements. A custom tune using platforms like UPREV or EcuTek is the final piece of the puzzle. A professional tuner can adjust fuel maps, ignition timing, and cam phasing to ensure all your modifications work in harmony.
A proper tune does more than just add peak horsepower; it improves drivability, increases fuel economy under cruising conditions, and can even add features like launch control or multiple map switching. It is the best way to ensure your investment in hardware pays off with reliable, consistent performance.
