What Makes the Renesis Performance Intake Different?

Unlike generic cold air intakes, the Renesis Performance unit uses a woven carbon fiber tube with a smooth interior surface that minimizes airflow turbulence. The material itself acts as a heat insulator, keeping incoming air cooler than metal or plastic alternatives. The kit includes a high-flow, washable dry filter (no oil needed) and all necessary mounting brackets, silicone couplers, and stainless steel clamps. The design is tuned for specific engine applications, maintaining correct MAF sensor positioning and air-fuel ratio integrity.

Key benefits you can expect after installation include:

  • Increased throttle response and a deeper induction sound
  • Reduced intake air temperatures by up to 15–20°F in stop-and-go driving
  • Typical peak gains of 8–12 horsepower and 6–10 lb-ft of torque (varies by vehicle)
  • Weight savings of 2–4 pounds compared to stock assemblies
  • Show-quality engine bay aesthetics with visible carbon fiber weave

Preparation: Setting Up Your Workspace and Vehicle

Proper preparation reduces the risk of mistakes and ensures a safe working environment. Follow these steps in order:

  1. Park on a level surface and engage the parking brake. If working on a sloped driveway, use wheel chocks.
  2. Turn off the engine and allow it to cool for at least 30 minutes. The intake manifold and surrounding components can remain hot enough to cause burns.
  3. Disconnect the negative battery terminal using a 10mm wrench or socket. This prevents accidental electrical shorts and resets the ECU adaptions, which helps the engine learn the new intake airflow more quickly.
  4. Remove any engine covers (cosmetic plastic covers) that obstruct access to the factory airbox. Use a trim tool or flathead screwdriver wrapped in tape to avoid scratching panels.
  5. Lay out all tools and parts within easy reach. Open the intake kit and verify every component matches the instruction manual. Inventory the bolts, clamps, and couplers.
  6. Take reference photos of the engine bay with the stock intake in place. These will help you remember hose routings and electrical connector locations.

Important safety note: Never work on a hot engine. Also, be mindful of moving parts (drive belts, radiator fans) that may start unexpectedly if the battery is reconnected prematurely.

Removing the Factory Intake System

With the battery disconnected and the engine cooled, proceed to remove the existing intake. The exact steps vary slightly by vehicle, but the general process is universal.

Step 1: Unplug Electrical Connectors

Locate the mass airflow (MAF) sensor and any secondary sensors (e.g., intake air temperature sensor) attached to the stock airbox or intake tube. Carefully press the release tab on each connector and pull straight out. Avoid yanking on the wires.

Step 2: Disconnect Hoses and Vacuum Lines

The stock intake often has one or more small-diameter vacuum lines running to the valve cover, evaporative emissions system, or crankcase ventilation. Use a flathead screwdriver to loosen hose clamps or simply pinch and twist rubber lines to free them. Label each hose with painter’s tape and a marker to avoid confusion during reinstallation.

Step 3: Unbolt the Airbox and Intake Tube

Starting at the throttle body, loosen the clamp securing the rubber intake boot. Then, working outward, remove the bolts or nuts holding the airbox to the fenderwell or engine bracket. A 10mm or 12mm socket is typical. For vehicles with a screw-type airbox lid, use a Phillips screwdriver. Lift the airbox out, along with the filter, then remove the intake tube.

Step 4: Remove the Resonator (if applicable)

Many factory intakes include a plastic resonator box that dampens noise. It may be held by one or two bolts underneath the vehicle or behind the bumper. Removing it can improve airflow and free up space for the new intake. Consult your service manual or the Renesis Performance guide for your specific model.

Step 5: Clean the Throttle Body Opening

With the intake boot removed, inspect the throttle body bore. If you see carbon deposits, consider cleaning it with throttle body cleaner and a soft brush while you have access. Dry it completely before proceeding. This step is optional but recommended for maximum performance.

Installing the Renesis Performance Carbon Fiber Intake

Now the real upgrade begins. Follow these steps in the exact order listed to avoid misalignment or leaks.

Step 1: Mount the Intake Bracket

Most Renesis Performance kits include a custom bracket that replaces the factory airbox mounting point. Attach this bracket to the vehicle using the provided hardware. Torque to the values specified in the instruction sheet (typically 8–12 ft-lb for M6 bolts). Use a torque wrench for consistency.

Step 2: Assemble the Carbon Fiber Tube with Sensors

If your kit requires transfer of the MAF sensor and IAT sensor from the factory intake, carefully remove them using a screwdriver to release the clips or small Torx screws. Install them onto the carbon fiber tube in the dedicated bungs. Use the supplied O-rings or gaskets; do not overtighten sensor screws. A dab of silicone grease on O-rings helps them seat without tearing.

Step 3: Connect Silicone Couplers and Clamps

Slide a stainless steel T-bolt clamp over each end of a silicone coupler, then fit the coupler onto the throttle body opening. Position the carbon fiber tube so its outlet end aligns with the coupler. Push the tube into the coupler and tighten the clamp just enough to hold it loosely – do not fully tighten yet. Repeat for the inlet side connecting to the air duct or filter.

Step 4: Position the Intake and Secure

With the tube roughly in place, install the filter onto the inlet side of the carbon tube. Most filters slide over and clamp. Then attach the tube to the bracket you installed earlier. Tighten the bracket bolts to specification. Now go back and tighten all T-bolt clamps (throttle body, filter, and any intermediate connections) to 3.5–4.5 ft-lb (about hand-tight plus a quarter turn with a screwdriver). Over-tightening can deform the couplers or crack the carbon fiber.

Step 5: Reconnect Hoses and Electrical Connectors

Reattach any vacuum lines or breather hoses to the fittings on the new intake tube. The kit should have barbed ports that align with the stock hose routing. Double-check your reference photos. Plug in the MAF and IAT connectors until they click. Ensure the wiring is routed away from hot surfaces and moving parts.

Step 6: Final Inspection

Before reinstalling any engine covers, visually inspect every clamp, hose, and connector. Rotate the throttle body linkage by hand (engine off) to ensure the coupler does not bind. Make sure the intake filter has adequate clearance from the fender, bumper, or radiator shroud. For vehicles with a cold air feed, ensure the filter is sealed within the factory ducting or an aftermarket cold air box.

Final Steps: Reconnecting the Battery and First Start

With the intake firmly installed, it’s time to bring the system to life.

  1. Reconnect the negative battery terminal and tighten the clamp. Torque to 6–8 ft-lb if specified by your vehicle manufacturer.
  2. Turn the ignition to the “ON” position (do not start) for about 5 seconds. This allows the fuel pump to prime and the ECU to begin its self-calibration. Turn the key off, then back on, and wait another 5 seconds.
  3. Start the engine. It may idle higher than normal for the first minute as the ECU adapts. Let it idle for 2–3 minutes without touching the accelerator. Listen for any whistling, hissing, or rattling noises that indicate a leak or loose part.
  4. Check for air leaks. While the engine is idling, spray a small amount of carb cleaner or start fluid around all coupler joints and sensor gaskets. If the idle speed changes, you have a leak – tighten the clamp or re-seat the coupler.
  5. Shut off the engine and re-torque the MAF sensor screws and any clamps that felt loose. Re-check all connections visually.
  6. Take a short test drive (2–3 miles) in varying conditions – city and light highway. Monitor the check engine light. If it comes on, scan for codes. A lean code often indicates a post-MAF air leak; a rich code may mean a MAF positioning issue.

Allow the ECU to complete its learning cycle over the next 50–100 miles. During this period, you may notice slight variations in idle stability as the fuel trims adjust.

Maintenance Tips for Long-Term Performance

Your carbon fiber intake requires minimal maintenance, but ignoring basic care can reduce efficiency and even damage the filter or sensors.

  • Clean or replace the filter every 15,000–20,000 miles (or more frequently if you drive in dusty conditions). For dry filters, use a vacuum or gentle compressed air from the inside out. Never use oil-based cleaners unless specified.
  • Inspect silicone couplers annually for cracking or hardening. Replace any coupler that feels brittle to avoid vacuum leaks.
  • Check T-bolt clamp torque every 10,000 miles. Vibration can loosen them over time. Tighten to 3.5–4.5 ft-lb.
  • Keep the carbon fiber surface clean using a mild soap and water solution. Avoid solvents that may damage the clear coat.
  • Monitor engine behavior. If you notice a sudden decrease in fuel economy or a rough idle, inspect the intake for leaks or obstructions before assuming a mechanical issue.

Troubleshooting Common Installation Issues

Even experienced installers sometimes encounter problems. Here are fixes for the most frequent issues:

  • Check engine light with lean code (P0171, P0174): Common cause – air leak after the MAF sensor. Re-tighten all clamps on the intake tube between the MAF and throttle body. Verify the MAF sensor O-ring is seated properly.
  • Whistling noise at idle: Usually a small vacuum leak from a forgotten hose or a loose coupler. Spray soapy water around joints while idling; bubbles indicate the leak.
  • Rough idle or stalling after installation: The ECU may need a reset. Disconnect the battery for 10 minutes, then reconnect and run the idle relearn procedure (turn key on, wait, start, idle 5 minutes with no accessories).
  • Filter making contact with bodywork: Adjust the intake tube rotation or shim the bracket. Do not force the filter into a position that pinches the coupler.
  • No noticeable performance gain: Ensure that the intake is receiving cool outside air, not recirculated engine bay heat. Consider adding a cold air box or air duct from the front grille. Also, verify you have the correct tune for your vehicle if applicable.

Performance Expectations and Real-World Results

After installation, many drivers report sharper throttle tip-in and a more aggressive induction growl at wide-open throttle. The carbon fiber construction keeps intake temperatures lower than aluminum or plastic intakes, especially in stop-and-go traffic. On the dyno, the Renesis Performance intake typically delivers 8–12 peak horsepower and 6–10 lb-ft of torque on naturally aspirated engines. For forced induction applications, gains are often larger due to improved flow under boost. However, individual results depend on the vehicle, existing modifications, and ambient conditions.

To maximize gains, pair the intake with a cat-back exhaust and a professional ECU tune. For more data on specific vehicle dyno charts, visit Renesis Performance’s FAQ page.
