Hey guys! Thinking about boosting the performance of your 2020 Lexus IS 350 F Sport? A great place to start is with an upgraded intake system. Not only can it improve horsepower and torque, but it can also enhance the sound of your engine, making your driving experience even more thrilling. Let's dive into everything you need to know about upgrading the intake on your Lexus IS 350 F Sport.

Why Upgrade Your Intake?

So, why should you even bother upgrading your intake? Well, the factory intake systems in many cars, including the Lexus IS 350 F Sport, are designed with efficiency and noise reduction in mind. This means they can be somewhat restrictive, limiting the amount of air that gets to your engine. By installing an aftermarket intake, you can significantly improve airflow, which can lead to several benefits:

• Increased Horsepower and Torque: More air means more efficient combustion, which translates to more power. You might see gains of anywhere from 5 to 15 horsepower, depending on the intake system and other modifications you have.
• Improved Throttle Response: An upgraded intake can make your throttle feel more responsive, giving you quicker acceleration and a more engaging driving experience. This is because the engine can breathe easier and react faster to your inputs.
• Enhanced Engine Sound: Let's be honest, who doesn't love a good engine note? Aftermarket intakes often amplify the sound of your engine, giving it a more aggressive and sporty tone. Imagine hearing that throaty growl every time you step on the gas – it's addictive!
• Better Fuel Efficiency (Potentially): In some cases, an improved intake can lead to better fuel efficiency. By optimizing the air-to-fuel ratio, your engine might burn fuel more efficiently, saving you money at the pump. However, this isn't always guaranteed, and your mileage may vary depending on your driving habits.

Types of Intakes for the 2020 Lexus IS 350 F Sport

When it comes to aftermarket intakes, you generally have two main types to choose from: short ram intakes and cold air intakes. Each has its pros and cons, so let's take a closer look:

Short Ram Intakes (SRI)

Short Ram Intakes, or SRIs, replace the stock airbox with a filter that sits directly on the intake tube in the engine bay. They are typically easier to install and less expensive than cold air intakes. Here's what you need to know:

• Pros:
  • Easy Installation: SRIs are generally straightforward to install, often requiring only basic tools and a couple of hours of your time. This makes them a great option for DIY enthusiasts.
  • Improved Throttle Response: Because the filter is closer to the engine, SRIs can provide quicker throttle response compared to the stock intake.
  • Enhanced Engine Sound: SRIs tend to amplify the engine sound more than cold air intakes, giving you that aggressive tone you're looking for.
• Cons:
  • Heat Soak: Since the filter is located in the engine bay, it can be susceptible to heat soak, which is when the filter draws in hot air from the engine. Hot air is less dense than cold air, which can reduce performance.
  • Less Horsepower Gains: Due to the potential for heat soak, SRIs may not provide as much horsepower gain as cold air intakes, especially in hot climates.

Cold Air Intakes (CAI)

Cold Air Intakes are designed to draw in cooler air from outside the engine bay. They typically extend the intake tube down into the fender well or behind the bumper, where the air is cooler and denser. Let's break down the details:

• Pros:
  • Greater Horsepower Gains: By drawing in cooler air, CAIs can provide more significant horsepower gains compared to SRIs, especially in hot weather. Cooler air means denser air, which leads to better combustion and more power.
  • Reduced Risk of Heat Soak: Because the filter is located away from the engine, CAIs are less susceptible to heat soak, ensuring consistent performance.
• Cons:
  • More Difficult Installation: CAIs can be more challenging to install than SRIs, often requiring more time and effort. You may need to remove parts of the bumper or fender to access the installation location.
  • Higher Price: CAIs tend to be more expensive than SRIs due to their more complex design and installation requirements.
  • Risk of Water Ingestion: If you live in an area with heavy rain or flooding, there's a risk that a CAI could suck water into the engine, which can cause serious damage. Some CAIs come with bypass valves to mitigate this risk.

Installation Tips and Considerations

Before you start wrenching on your Lexus, here are some essential installation tips and considerations to keep in mind:

• Read the Instructions: Always read the installation instructions carefully before you begin. This will help you understand the process and avoid any mistakes. Seriously, don't skip this step!
• Gather Your Tools: Make sure you have all the necessary tools before you start. This may include sockets, wrenches, screwdrivers, and pliers. Having the right tools will make the job much easier.
• Disconnect the Battery: Disconnect the negative terminal of your battery before you start working on the intake. This will prevent any electrical issues.
• Take Your Time: Don't rush the installation process. Take your time and double-check your work to ensure everything is properly installed.
• Watch Installation Videos: Sometimes, seeing the process in action can be incredibly helpful. Look for installation videos on YouTube or other online resources.
• Consider Professional Installation: If you're not comfortable installing the intake yourself, consider having a professional do it. A qualified mechanic can ensure the intake is installed correctly and safely.

Maintaining Your Upgraded Intake

Once you've installed your new intake, it's essential to maintain it properly to ensure it continues to perform at its best. Here are some maintenance tips:

• Clean the Air Filter: Regularly clean the air filter to remove dirt and debris. Depending on the type of filter, you may need to use a special cleaning solution and oil.
• Inspect the Intake Tube: Check the intake tube for any cracks or damage. Replace the tube if you find any issues.
• Tighten Connections: Periodically check the connections to ensure they are tight and secure. Loose connections can cause air leaks, which can reduce performance.

Performance Expectations

So, what kind of performance gains can you expect from an upgraded intake on your 2020 Lexus IS 350 F Sport? While the exact numbers will vary depending on the intake system and other modifications, here's a general idea:

• Horsepower: You can expect to see gains of around 5 to 15 horsepower.
• Torque: Similarly, you might see an increase of 5 to 15 lb-ft of torque.
• Throttle Response: You'll likely notice a significant improvement in throttle response, making your car feel more responsive and fun to drive.
• Engine Sound: The engine sound will be noticeably more aggressive and sporty, enhancing your overall driving experience.

Keep in mind that these are just estimates, and your actual results may vary. To get the most out of your upgraded intake, consider pairing it with other performance modifications, such as an aftermarket exhaust system or a tune.
