Upgrading your 2019 Lexus IS350 with a cold air intake is a fantastic way to boost its performance and add a little extra thrill to your driving experience. In this guide, we'll dive deep into why a cold air intake can be a game-changer, what to look for when choosing one, and how to ensure you get the most out of your upgrade. Let's get started!

Why Choose a Cold Air Intake for Your Lexus IS350?

So, you're probably wondering, "Why should I even bother with a cold air intake?" Well, guys, the answer is pretty straightforward: performance. Your engine needs air to burn fuel, and the cooler the air, the denser it is. Denser air means more oxygen, which results in a more efficient combustion process. This translates to increased horsepower, improved torque, and better throttle response. Who wouldn't want that?

Increased Horsepower and Torque

One of the most noticeable benefits of installing a cold air intake is the potential increase in horsepower and torque. While the exact gains can vary depending on the specific intake system and other modifications you might have, you can generally expect to see an improvement of around 5 to 15 horsepower. That might not sound like a lot, but you'll definitely feel the difference when you put your foot down. The improved torque also means better acceleration, making your IS350 even more fun to drive.

Enhanced Throttle Response

Another significant advantage of a cold air intake is the improved throttle response. With a more direct and less restrictive airflow path, your engine can respond more quickly to your commands. This means quicker acceleration and a more engaging driving experience. Say goodbye to that slight lag you might have noticed and hello to instant power!

Improved Fuel Efficiency

While performance is the main reason most people opt for a cold air intake, some systems can also lead to improved fuel efficiency. By allowing your engine to breathe more freely, it doesn't have to work as hard to produce power. This can result in a slight increase in gas mileage, especially during highway driving. It's not a massive improvement, but every little bit helps, right?

Aggressive Sound

Let's be honest, who doesn't love a good engine sound? A cold air intake can add a more aggressive and sporty tone to your IS350's engine. You'll hear a deeper growl when you accelerate, which can make your driving experience even more enjoyable. It's like giving your car a voice that matches its performance.

Key Considerations When Choosing a Cold Air Intake

Alright, so you're convinced that a cold air intake is the way to go. But with so many options on the market, how do you choose the right one for your 2019 Lexus IS350? Here are some key factors to consider:

Material Quality

The material quality of the intake system is crucial for its durability and performance. Look for intakes made from high-quality materials like aluminum or carbon fiber. Aluminum is lightweight and offers excellent heat dissipation, while carbon fiber is even lighter and provides superior insulation. Avoid intakes made from cheap plastic, as they may not withstand the heat and stress of the engine bay.

Filter Type

The air filter is another critical component of the intake system. There are two main types of filters: oiled and dry. Oiled filters offer better filtration and can trap smaller particles, but they require regular cleaning and re-oiling. Dry filters are easier to maintain, as they can simply be cleaned with compressed air, but they may not offer the same level of filtration. Consider your driving environment and maintenance preferences when choosing a filter type.

Intake Tube Design

The design of the intake tube can significantly impact airflow and performance. Look for systems with smooth, mandrel-bent tubes that minimize turbulence and maximize airflow. Avoid systems with sharp bends or restrictive designs, as they can reduce performance. A well-designed intake tube will help your engine breathe more efficiently and produce more power.

Heat Shielding

One of the main goals of a cold air intake is to draw in cooler air from outside the engine bay. However, if the intake is not properly shielded from engine heat, it can end up sucking in hot air, which defeats the purpose. Look for systems that include a heat shield or enclosure to protect the filter from engine heat. This will help ensure that your engine is getting the coldest air possible.

Ease of Installation

Unless you're a seasoned mechanic, you'll want to choose an intake system that's relatively easy to install. Look for systems that come with clear instructions and all the necessary hardware. Some intakes are designed to be direct replacements for the factory system, making installation a breeze. Others may require some modifications or additional parts. Consider your skill level and the amount of time you're willing to spend on the installation process.

Installation Tips and Tricks

So, you've got your new cold air intake, and you're ready to install it. Here are a few tips and tricks to make the process go smoothly:

Read the Instructions Carefully

This might seem obvious, but it's worth mentioning. Before you start tearing things apart, take the time to read the instructions thoroughly. Make sure you understand each step and have all the necessary tools and parts. This will save you time and frustration in the long run.

Disconnect the Battery

Before you start working on any electrical components, disconnect the negative terminal of your battery. This will prevent any accidental shorts or damage to your vehicle's electrical system.

Take Your Time

Don't rush the installation process. Take your time and be careful not to damage any parts. If you're not sure about something, consult the instructions or seek help from a professional.

Double-Check Everything

Once you've installed the intake, double-check all the connections and make sure everything is tight. Check for any leaks or loose parts before starting the engine. It's better to catch a problem early than to have it cause damage later.

Clean the Mass Air Flow (MAF) Sensor

It's a good idea to clean the MAF sensor when installing a new intake. The MAF sensor measures the amount of air entering the engine, and a dirty sensor can cause performance problems. Use a MAF sensor cleaner to gently clean the sensor, and be careful not to damage it.

Maintaining Your Cold Air Intake

Once you've installed your cold air intake, it's important to maintain it properly to ensure optimal performance and longevity. Here are a few maintenance tips:

Clean the Filter Regularly

The air filter is the most important part of the intake system, so it's crucial to keep it clean. Depending on the type of filter you have, you'll need to clean it every 10,000 to 25,000 miles. Oiled filters require a special cleaning kit, while dry filters can be cleaned with compressed air.

Inspect the Intake Tube

Regularly inspect the intake tube for any cracks, leaks, or damage. Replace the tube if you find any problems. A damaged intake tube can reduce performance and allow unfiltered air to enter the engine.

Check the Connections

Periodically check all the connections to make sure they're tight. Loose connections can cause air leaks, which can affect performance.

Listen for Unusual Noises

Pay attention to any unusual noises coming from the engine bay. A whistling or hissing sound could indicate an air leak, while a rattling sound could indicate a loose part.
