You can install several performance parts yourself, including a drop-in air filter, a Pedal Commander® throttle response controller, and some bolt-on intakes, chassis braces, and exhaust kits. The right choice depends on your vehicle, your tools, and what you want to improve.
At Pedal Commander®, we want you to know what a project involves before you order the part. A plug-in controller and an exhaust system may both be advertised as easy upgrades, but they demand different amounts of time, equipment, and mechanical confidence.
Below, we rank five DIY upgrades from the simplest installation to the most involved. We also explain what each part changes so you can choose an upgrade that matches your goal.
DIY Performance Parts Ranked by Difficulty, Tools and Time
We rank these parts by access, installation steps, tool requirements, and the checks needed before driving. This is an installation ranking, not a ranking of horsepower gains.
The times below are planning estimates for straightforward, compatible applications. They include basic preparation and final checks. Difficult access, damaged connectors, seized hardware, or additional disassembly can extend the job.

Our guide to bolt-on performance upgrades explains how these parts fit into a broader modification plan.
1. Drop-In Performance Air Filter: The Simplest Starting Point
A drop-in performance air filter replaces the original filter inside your existing airbox. You retain the factory intake housing and tubing, which keeps the installation relatively simple.
On an accessible airbox, the job usually involves opening the housing, removing the old filter, checking the sealing surfaces, and fitting the replacement. Follow the instructions for your exact filter: sealing requirements can differ between products.
Why we include it: It is an approachable first project that helps you become familiar with the intake system.
What to expect: A drop-in filter alone should not be treated as a major horsepower upgrade. The practical appeal is its simple installation and, for serviceable products, reusable construction.
What can complicate it: Some vehicles have awkward airbox access or require nearby components to be moved. Check access before assuming the job will take five minutes.
After installation, confirm that the filter sits correctly and that every airbox clip or fastener is secured. For more ideas at this difficulty level, explore our no-tool and simple bolt-on modifications.
2. Pedal Commander® Throttle Response Controller: A Simple Upgrade for Pedal Feel
If your electronic accelerator feels sluggish, our throttle response controller is a straightforward DIY option.
Pedal Commander® connects inline at the accelerator pedal. It adjusts the relationship between pedal input and the signal sent to the vehicle’s electronic control unit, giving you control over accelerator sensitivity. It does not add horsepower or repair an underlying mechanical problem.
Why we include it: On compatible vehicles, installation uses plug-and-play connectors and avoids engine-bay disassembly, wire cutting, and ECU flashing.
What to expect: A change in pedal response according to the setting you choose. If your goal is increased engine output, you will need to evaluate upgrades intended to produce additional power.
What can complicate it: A connector positioned high under the dashboard, a secondary locking tab, or previously modified wiring can make access more difficult.
You can read more about the distinction between pedal response and engine output in Does Pedal Commander® Increase Horsepower?.
Does Pedal Commander®'s throttle response controller require professional installation?
No. On a compatible vehicle with accessible, unmodified pedal wiring, Pedal Commander® is designed for DIY installation and normally does not require a professional installer. You connect the supplied harness between the factory accelerator pedal connector and the pedal assembly, secure the cable, and mount the controller.
Our installation guide requires you to let the vehicle’s electronics shut down before disconnecting the pedal. Allow time for that preparation as well as the physical installation.
Prepare the Vehicle Before Connecting the Harness
Park securely and turn the ignition off. Remove the key where applicable, keep the proximity key fob at least 35 feet away so it does not trigger any electronics on, and leave the driver’s door open while waiting approximately 10–15 minutes, as directed in our installation guide.
Connect, Secure and Check
-
Locate the accelerator pedal connector. Identify its locking mechanism before attempting to release it.
-
Disconnect the factory plug carefully. Handle the connector housing rather than pulling on the wires.
-
Connect the Pedal Commander® harness inline. Fully seat both connections and re-engage the locking tabs.
-
Secure the cable and mount the controller. Keep wiring clear of the pedals, steering components, seat movement, and your feet.
-
Check the installation before driving. Confirm that the pedals move freely, the wiring stays in place, and no warning lights appear.
Some connector locks may need a small screwdriver or pick tool. If a connection will not release or fit correctly, check the instructions rather than forcing it. Our throttle response controller installation guide covers the process in more detail.
Seek professional assistance if you cannot identify the correct connector, discover damaged wiring, or cannot secure the installation properly. Once everything checks out, start with a mild response setting while you become familiar with the pedal feel.
3. Bolt-On Strut Tower Brace: A Manageable Chassis Upgrade
A strut tower brace connects the upper strut mounting areas to add reinforcement. Direct-fit versions can be approachable DIY projects when they use accessible mounting points and require no drilling.
Why we include it: A straightforward brace installation usually involves relatively few components.
What to expect: Its purpose is chassis reinforcement. The difference you notice depends on your vehicle’s existing structure, suspension, and driving conditions. It does not increase horsepower.
What can complicate it: Tight engine-bay clearance, covers that need removal, or interference with existing modifications.
Allow approximately 30–60 minutes for a straightforward bolt-on installation. Tight clearance or additional disassembly can extend that estimate.
We recommend reading the mounting instructions before purchasing. Use the specified torque values and confirm clearance around the hood, hoses, wiring, and engine components. Only remove the fasteners identified in the instructions, and leave other suspension fasteners undisturbed.
4. Intake Kit: More Steps, Still Within DIY Reach
An intake kit changes more of the intake system than a drop-in filter. Depending on the design, it may replace tubing, the airbox, the filter, and associated brackets.
Why we include it: Selected vehicle-specific kits can be installed with ordinary hand tools and detailed instructions.
What to expect: Intake sound may change, and some applications have documented power gains. Look for testing on your exact vehicle and engine rather than assuming every kit delivers the same result.
What can complicate it: Sensor transfers, vent-line connections, limited access, and additional brackets or shields.
Before buying, confirm that the exact intake kit is designed to work with your vehicle’s factory ECU calibration. A kit that requires an ECU tune or additional modifications falls outside the factory-tune-compatible category covered here.
Follow the exact instructions for sensor orientation, hose connections, any required battery-disconnection procedure, and final inspection. Our cold air intake guide can help you compare this upgrade with a simpler replacement filter.
5. Direct Bolt-On Axle-Back Exhaust: A Larger DIY Project
A direct bolt-on axle-back exhaust replaces the rear exhaust section using existing joints and mounting locations. It can be installed at home by a suitably equipped DIY owner, but it demands more preparation than a filter or pedal controller.
Why we include it: A genuinely direct-fit system can avoid welding and extensive exhaust disassembly.
What to expect: The clearest change is often exhaust sound. Do not assume a louder exhaust produces a substantial horsepower increase.
What can complicate it: Rusted fasteners, stubborn rubber hangers, heavy components, poor access, and time spent aligning the tips.
Check the installation method before buying. Choose a system that connects at the existing exhaust joints without cutting or welding. Some axle-back systems require cutting the factory exhaust, so they fall outside the direct bolt-on category covered here.
Let the exhaust cool completely. If underbody access requires raising the vehicle, use appropriate supports and the vehicle manufacturer’s lifting instructions; never work underneath a vehicle supported only by a jack.
After fitting the system, verify clearances, alignment, fastener torque, and leaks. If you lack safe access or the hardware will not release, arrange installation assistance.
How We Recommend Choosing Your First DIY Upgrade
Start with the change you actually want:
-
Adjustable accelerator response: Consider Pedal Commander®.
-
A simple intake-related project: Start with a drop-in filter.
-
Chassis reinforcement: Compare direct-fit strut tower braces.
-
Intake sound and potential additional power: Research a kit tested for your engine and compatible with your calibration.
-
A different exhaust note: Compare direct bolt-on axle-back systems.
Before ordering, confirm the exact year, make, model, engine, and any relevant trim differences. Our car part compatibility guide explains what to check.

Frequently Asked Questions
Which performance parts can I install without professional help?
A drop-in air filter and a compatible Pedal Commander® throttle response controller are approachable starting points. Selected bolt-on braces, factory-tune-compatible intakes, and direct bolt-on axle-back exhausts can also suit DIY installation when you have the required tools and understand the instructions.
Do I need specialized tools to install Pedal Commander®?
Most compatible installations do not require specialized automotive tools. Depending on the vehicle, a small screwdriver or pick may help release the factory connector lock; the connection should never be forced.
How much time should I set aside for Pedal Commander® installation?
We suggest allowing approximately 20–30 minutes for an uncomplicated installation, including preparation and final checks. Our instructions include a 10–15-minute wait for the vehicle’s electronics to shut down, and difficult connector access can add time.
Does Pedal Commander® increase horsepower?
No. Pedal Commander® adjusts accelerator sensitivity and throttle response without adding engine horsepower. We recommend it for drivers who want to change pedal feel rather than increase peak engine output.
Does “bolt-on” mean a part is easy for a beginner to install?
Not necessarily. A bolt-on part may still require underbody access, sensor transfers, precise torque settings, or removal of several factory components. Read the instructions for the exact part number before judging the difficulty.
Can I install an intake without tuning the ECU?
Yes, if the intake manufacturer explicitly specifies compatibility with your vehicle’s factory calibration. Check the exact kit and engine application, because tuning requirements vary between products.
