The right modifications enhance horsepower, improve handling, increase braking efficiency, and elevate the overall driving experience. Below are the most critical aftermarket and performance-focused parts that every SRT4 owner should consider.

1. Turbocharger – The Heart of Performance

The turbocharger is the cornerstone of the Neon SRT4’s performance, responsible for forced induction that significantly boosts engine power. The factory-installed turbocharger delivers approximately 230 horsepower, a substantial increase over naturally aspirated engines of similar size.

For drivers seeking more aggressive performance, aftermarket turbochargers offer greater airflow, higher boost pressure, and improved throttle response. Upgraded units such as the Garrett GT28RS, BorgWarner EFR, or Precision 6262 are popular choices that can support 300–500+ horsepower with proper supporting modifications.

Beyond power gains, modern turbo systems also improve fuel efficiency under partial load by reducing pumping losses and enhancing combustion efficiency. Proper tuning, intercooling, and oil management are crucial when upgrading to ensure reliability and longevity.

2. Performance Exhaust System – Unleash Engine Efficiency

A high-flow performance exhaust system is vital for maximizing the SRT4’s engine output. The stock exhaust system restricts exhaust gas flow, limiting engine breathing and power potential.

Aftermarket systems—such as cat-back or turbo-back setups—reduce backpressure, allowing spent gases to exit more efficiently. This results in improved horsepower, torque, and throttle response. Stainless steel construction ensures durability and resistance to corrosion.

In addition to performance, a performance exhaust enhances the vehicle’s auditory presence, delivering a deeper, more aggressive tone that complements the SRT4’s sporty character. Options range from mild resonated systems for daily driving to full race-style setups for track use.

3. Cold Air Intake System – Optimize Airflow and Combustion

A cold air intake (CAI) system dramatically improves engine performance by delivering cooler, denser air to the combustion chamber. Cooler air contains more oxygen, leading to more efficient fuel burn and increased power output.

Unlike stock intake systems that draw warm air from the engine bay, a CAI relocates the air filter to a cooler area—often near the front bumper or fender—where it can access ambient air. High-flow conical filters and smooth intake tubing further reduce turbulence and restriction.

Most cold air intakes provide noticeable gains in mid-range torque and throttle responsiveness. They also enhance engine sound during acceleration and are among the easiest and most cost-effective performance upgrades available.

Performance suspension systems typically include lowering springs or coilovers, upgraded shocks/struts, and reinforced sway bars. These components lower the vehicle’s center of gravity, reduce body roll, and improve tire contact with the road during cornering.

Adjustable coilovers allow fine-tuning of ride height, damping, and stiffness to match driving conditions—whether for daily comfort or aggressive track performance. Pairing the suspension upgrade with performance alignment settings (camber, toe) further enhances grip and tire wear longevity.

5. Upgraded Brake Systems – Safety and Performance Combined

With increased speed and performance comes the need for superior stopping power. The brake system is not just a safety feature—it's a critical performance component.

The stock SRT4 brakes are capable, but under repeated hard use (such as track days or spirited driving), they are prone to fade due to heat buildup. Upgraded brake kits address this with larger, slotted or drilled rotors, multi-piston calipers (e.g., Brembo or Wilwood), and high-performance brake pads designed for elevated temperatures.

Vented rotors and better thermal materials improve heat dissipation, reducing brake fade and increasing consistency. Stainless steel braided brake lines provide a firmer pedal feel and prevent expansion under pressure. Together, these upgrades ensure reliable, responsive braking even in demanding conditions.

Important: When modifying your Neon SRT4, always ensure compatibility between upgraded components. For example, adding a larger turbocharger may require supporting mods like upgraded fuel injectors, an intercooler, and a custom ECU tune. Similarly, lowering the car with a sport suspension may necessitate adjustments to camber and alignment. Consult with experienced tuners or reputable vendors to build a balanced, reliable performance package.
