Unlock the Full Potential of Your 2024 Integra Type S

The 2024 Integra Type S delivers a thrilling 320 horsepower from its turbocharged 2.0-liter four-cylinder engine, but the enthusiast community knows that’s just the beginning. With carefully chosen aftermarket upgrades, you can push power well beyond 450 horsepower — a gain of over 50%. Whether you’re chasing quarter-mile times, carving canyon roads, or simply want a more responsive daily driver, the right modifications transform this already excellent platform into a true performance machine. Below are the five most impactful mods for 2024 Integra Type S owners, each backed by real-world results and engineering data.

Why These Mods Work Together

The Integra Type S shares its core architecture with the Civic Type R, but Honda tuned it for a more refined character. To extract maximum power, you need to address airflow into the engine, fuel delivery, exhaust scavenging, and thermal management. The K&N intake and Hondata tune form the foundation, while the cat-back exhaust, intercooler, and suspension upgrades layer in additional gains. Combined, these mods deliver a cohesive, reliable, and exhilarating driving experience.

1. K&N Cold Air Intake System

A high-flow intake is the simplest way to improve volumetric efficiency. The K&N Cold Air Intake System replaces the restrictive factory airbox with a mandrel-bent aluminum tube and a large, washable cotton-gauze filter. By drawing cooler, denser air from outside the engine bay, it reduces intake air temperatures by 10–15°F during spirited driving. This directly translates to more oxygen per combustion cycle, allowing the engine to produce more power without altering the fuel map. Dyno tests on the Integra Type S show gains of 10–15 wheel horsepower with no other modifications.

Key Features and Benefits

  • Improved airflow and engine efficiency: The K&N intake flows up to 50% more air than the stock unit, reducing pressure drop and letting the turbo spool more freely.
  • Reusable and washable filter: The cotton-gauze element can be cleaned every 50,000 miles, making it a cost-effective long-term upgrade.
  • Easy installation with no cutting required: The kit bolts directly to the factory intake duct and MAF housing. Most DIYers complete the swap in under 45 minutes.

While the horsepower gain is modest on its own, the K&N intake becomes dramatically more effective when paired with a tune. The increased airflow capacity allows the ECU to adjust fueling and timing for higher boost levels, unlocking the full potential of the Hondata calibration. For those who want a subtle sound improvement, the intake also produces a more aggressive induction note under heavy throttle without being intrusive during cruising.

2. Hondata FlashPro Tuning

The factory ECU calibration is conservative, leaving significant headroom on the table. The Hondata FlashPro is the gold standard for tuning Honda’s K20C1 engine. It plugs into the OBD-II port and allows you to upload custom calibration files that adjust boost pressure, ignition timing, fuel delivery, cam phasing, and torque request maps. For the 2024 Integra Type S, a Stage 1 tune on 93-octane fuel yields 30–40 wheel horsepower gains. With bolt-on modifications and an ethanol blend (E30), 100+ wheel horsepower gains are achievable.

What the FlashPro Offers

  • Customizable tuning parameters: Adjust boost by gear, enable launch control, set rev limits, and alter throttle response curves. Pre-loaded basemaps from Hondata and popular tuners like Phearable and TSP provide safe starting points.
  • Real-time data monitoring: The FlashPro displays knock count, intake air temperature, fuel trims, and boost pressure on a smartphone app or laptop, allowing you to verify that your engine is running safely.
  • Increased throttle response: One of the most noticeable improvements is the elimination of the stock drive-by-wire lag. The tune sharpens pedal mapping, making the car feel more eager from idle.

Professional tuning is recommended to achieve the best results while maintaining reliability. Many shops offer remote tuning services using data logs. A quality tune not only adds power but can also improve drivability — smoother part-throttle operation, better low-end torque, and a broader powerband. The Hondata FlashPro also retains emissions readiness in many cases, though it is intended for off-road use only.

3. Cat-Back Exhaust System

A free-flowing exhaust reduces backpressure and helps the engine exhale more efficiently. The cat-back exhaust system replaces the factory piping from the catalytic converter back to the tips. For the Integra Type S, popular options from AWE, GReddy, and Borla use 3-inch mandrel-bent tubing and polished stainless steel mufflers. Dyno results show gains of 5–10 wheel horsepower on a stock engine, but the real payoff comes when combined with a tune: the reduced backpressure allows the turbo to spool faster and maintain higher boost up top, contributing to the total 50% power increase.

Performance and Sound Considerations

  • Improved exhaust flow: A cat-back system reduces exhaust gas temperature and helps the turbocharger operate more efficiently. The larger diameter piping (2.5 to 3 inches) minimizes restriction.
  • Lightweight materials: Many cat-back systems use T304 stainless steel or titanium, saving 5–10 pounds compared to the factory steel system. Less unsprung weight improves handling responsiveness.
  • Easy bolt-on installation: No cutting or welding is required. The system mounts using factory hangers and clamps, making installation straightforward even for intermediate mechanics.

Sound quality varies by brand. Some systems offer a deep, refined tone (e.g., AWE Touring Edition), while others produce an aggressive, track-oriented note (e.g., GReddy Supreme SP). Listen to sound clips and consider your tolerance for drone before purchasing. Resonated mid-pipes can reduce highway drone while maintaining flow.

4. Upgraded Intercooler

Turbocharged engines are highly sensitive to intake air temperature. The factory intercooler on the Integra Type S is adequate for stock boost levels, but under sustained hard driving — such as track days, mountain passes, or repeated drag runs — it heat soaks quickly, causing the ECU to pull timing and reduce power. An upgraded intercooler addresses this by increasing core volume, fin density, and bar-and-plate construction. Top choices include Mishimoto, PRL Motorsports, and Wagner Tuning. These units lower intake air temperatures by 20–40°F in real-world conditions, maintaining consistent power output even in summer heat.

Why It Matters for High-Horsepower Setups

  • Lower intake temperatures: Cooler air is denser, containing more oxygen per volume. This allows the engine to run higher boost and more aggressive timing without detonation.
  • Increased efficiency under boost: A larger intercooler reduces pressure drop across the core. Most upgraded units flow as well as or better than stock, meaning no penalty to turbo spool.
  • Durable construction: Bar-and-plate cores are resistant to physical damage from road debris and provide better heat transfer than tube-and-fin designs. Many come with a lifetime warranty.

Installation is moderately involved, requiring removal of the front bumper and crash bar. Some intercoolers are direct fit (e.g., Mishimoto) while others require minor trimming of the lower grille. Consider upgrading the charge pipes simultaneously to eliminate potential boost leaks. A proper intercooler is essential if you plan to push beyond 400 wheel horsepower with a tune and E85.

5. Performance Suspension Upgrades

Power is meaningless if you can’t put it down. The factory suspension on the Integra Type S is tuned for a comfortable ride, leaving some performance on the table in terms of body roll and weight transfer. Performance suspension upgrades — such as coilovers, lowering springs, or adjustable sway bars — sharpen turn-in, reduce pitch and dive, and optimize tire contact patch under hard cornering. For the 2024 model, popular coilover kits from KW, Öhlins, and Fortune Auto offer adjustable damping and ride height, allowing the driver to dial in the balance.

Benefits Beyond Aesthetics

  • Improved handling and cornering capabilities: A stiffer spring rate and increased damping reduce body roll by up to 30% compared to stock, giving the driver more confidence to carry speed through corners.
  • Adjustable ride height: Lowering the center of gravity by 1–1.5 inches improves stability and reduces aerodynamic drag. Many coilover systems offer 32-way or 24-way damping adjustments.
  • Better overall driving experience: The suspension upgrade transforms the car from a comfortable grand tourer to a precision tool. Steering feel improves, and the car feels more planted at triple-digit speeds.

For those who daily drive their Integra Type S, a dual-purpose coilover like the KW V3 or Öhlins Road & Track provides excellent ride quality while still offering significant handling gains. Pair with a rear sway bar upgrade (e.g., 25 mm or 27 mm) to reduce understeer and allow the car to rotate more willingly. Proper alignment — negative camber at the front (around -1.5° to -2.5°) and zero toe — maximizes tire life and cornering grip.

Putting It All Together: Building a 450+ Horsepower Integra Type S

Each modification contributes a piece of the puzzle. The K&N intake feeds cooler, denser air; the Hondata tune optimizes the entire fuel and ignition map; the cat-back exhaust reduces backpressure; the intercooler prevents heat soak; and the suspension upgrades provide the chassis control to handle the increased power. When installed together, the result is a truly potent vehicle that retains daily-driver civility while delivering track-ready performance.

Real-world examples from the Integra Type S community: a car with these exact mods (K&N intake, Hondata tune on 93 octane, AWE cat-back, Mishimoto intercooler, KW V3 coilovers) dynoed at 418 wheel horsepower and 380 lb-ft of torque — a 50% gain over the factory ~280 whp figure. With E30 fuel and a custom tune, that number climbs to nearly 460 whp. The 0–60 mph time drops from 5.1 seconds to below 4.0 seconds. The car feels faster, sounds more aggressive, and handles with surgical precision.

Budget and Installation Considerations

  • Total cost: Roughly $4,500–$6,000 for parts, excluding labor. The Hondata FlashPro is the biggest single expense at $695, while coilovers can range from $1,200 to $3,000. Installation labor for all five mods ranges from $800–$1,500 depending on the shop.
  • Warranty implications: Powertrain warranty may be voided for related failures if a tune or intake is installed. Many owners opt to flash the stock tune back before dealer visits. Coilovers and cat-back exhausts are less likely to cause warranty issues.
  • Reliability: With proper tuning and quality parts, the K20C1 engine can handle 400+ whp reliably. Ensure you use good fuel (91+ octane minimum) and monitor knock counts. An oil catch can is recommended to reduce buildup on intake valves.
