Unlocking Power: Top 5 Ways to Increasing Your Vehicle's Engine Performance

Your vehicle's engine performance is a crucial aspect in enjoying your driving experience. Whether you are a speed enthusiast or simply want better performance, enhancing your engine can be a rewarding endeavor. From basic maintenance to advanced modifications, there are various ways to unleash the full potential of your vehicle's engine. In this article, we'll explore the top 5 methods to increase your engine's performance!

Engine Performance

Maintenance First:

Before diving into modifications, it's essential to ensure your vehicle's engine is well-maintained. Regular oil changes, various filter replacements, and spark plug inspections are fundamental for optimal performance. Additionally, keeping the engine bay clean and checking for any leaks or worn-out components can prevent potential issues and maintain efficiency. Proper maintenance sets the foundation for any modifications and ensures longevity for your engine in any performance applications.

→ 1. Cold Air Intake

Installing a cold air intake system is a popular and relatively simple modification to enhance engine performance. By replacing the stock air intake system with a cold air intake, you allow cooler, denser air to enter the engine, resulting in improved combustion and power. This increased cooler air can lead to noticeable gains in horsepower, torque and even gas mileage (depending on how restrictive the factory intake box/system is, throughout the whole power band. Cold air intakes are available for a wide range of vehicles and can often be installed with basic tools and minimal mechanical knowledge.

Heat shield:

Adding a heat shield on top of your cold air intake will help to keep more of the cold air going into your engine and the hot air out. Oftentimes a heat shield will be a part of the cold air intake kit but if not, buying one for your vehicle or making one will help to increase the efficiency of your intake which will boost performance.

 2.Catback Exhausts

Upgrading your vehicle's exhaust system with a catback exhaust can offer significant improvements in performance and sound. Catback exhaust systems replace the exhaust components from the catalytic converter back to the rear of the vehicle, allowing for better airflow and reduced back pressure. This results in enhanced engine efficiency, increased horsepower, and a more aggressive exhaust note. Additionally, many catback exhaust systems are constructed from high quality materials such as stainless steel or titanium.

Catback: Catback exhaust systems refer to all of the components that exhaust gasses flow through after exiting the vehicle's catalytic converter hence from the cat, back.

Budget Options:

If buying a full cat back exhaust system is going to be to expensive you have two options regarding this issue:

Firstly you can see if there are any used catback exhausts for sale, obviously being used, the quality will not be pristine but the price drop can help you when buying an exhaust system. 

Secondly if there are no used exhaust systems for sale you can always simply replace your  resonator and muffler/s with high flow high performance parts. This will allow you to tune the sound and increase performance all at a lower price but understand that by not buying an actual system you will not reap the full performance benefits!

 3.Throttle Body

The throttle body plays a crucial role in regulating the airflow into the engine. By upgrading to a larger throttle body, you can increase the volume of air entering the engine, leading to improved throttle response and horsepower gains. Additionally, some aftermarket throttle bodies feature smoother bore designs and enhanced airflow characteristics, further optimizing engine performance. However, it's essential to ensure compatibility with your vehicle's engine management system and other components when upgrading the throttle body.


Some throttle bodies incorporate different MAF (Mass Airflow Sensors) which will cause issues in your intake system that will need to be tuned for in order for your engine to work, and work efficiently also!

 4.Porting and Polishing

Porting and polishing the engine's intake and exhaust ports can yield substantial performance gains, particularly in high-performance applications. This process involves removing imperfections and restrictions from the intake and exhaust ports, allowing for smoother airflow and increased volumetric efficiency.

While porting and polishing can be a labor-intensive and technically challenging task, the results can be well worth the effort and usually for a very low or even free price!

Professional engine builders and performance shops often offer porting and polishing services tailored to specific engine configurations and performance goals but this can be done, if careful, by yourself also.

Tool Recommendations:

-Dremel Tool.

-Grinding/Sanding Bits.



-Heavy Cleaning solution.

-Compressed air.

→ 5.Increasing Boost

For forced induction engines, increasing boost pressure is a tried and true method of boosting performance. 

Forced Induction: Forced induction is used to artificially increase the density of the intake air, in order to reduce the loss of power at higher altitudes.


By installing a boost controller, you can precisely control the amount of boost delivered to the engine from the turbo, maximizing power output while ensuring safe operating conditions. 


Upgrading supercharger pulleys (decreasing size) can increase the speed at which the supercharger spins, resulting in higher boost levels and increased horsepower when tuned. 


It's crucial to tune the engine's fuel and ignition parameters accordingly to prevent detonation and engine damage with the increased boost from these modififctions.

What if your vehicle doesn't have forced induction?

If your vehicle does not have a turbo or supercharger do not fear! Understanding that you can move anywhere in regards to making power will give you the edge in creating a powerhouse of an engine.

Aspiration: Naturally Aspirated or naturally 'breathing' engines, defines those that take in air under normal means at normal atmospheric pressures.

What to do?

Find what modifications are common, accessible and within your budget! Things i'd recommend checking; Supercharger kits, Turbo kits and Camshafts/ other upgraded valvetrain upgrades. These are some of the best mods to move your naturally aspirated engine to the next level in your performance journey.


Q: Will these modifications void my vehicle's warranty?

A: It depends on the specific terms of your vehicle's warranty and the modifications made. Some aftermarket upgrades may void certain aspects of the warranty, while others may not. It's essential to research and consult with your vehicle manufacturer or authorized dealer before making any modifications.

Q: Are these modifications street legal?

A: Many aftermarket performance upgrades, such as cold air intakes and catback exhausts, are designed to comply with emissions regulations and are street legal. However, it's essential to verify the legality of specific modifications in your area, as regulations can vary by location.


Enhancing your vehicle's engine performance can be a fulfilling journey that unlocks newfound excitement from your vehicle. From basic maintenance to advanced modifications, there are various ways to unleash the full potential of your engine. By following the top 5 methods outlined in this article – including cold air intake, catback exhausts, throttle body upgrades, porting and polishing, and increasing boost – you can transform your vehicle into a high-performance machine.
