2025 Lexus IS 350 F Sport Intake Upgrade Guide

So, you're looking to boost the performance of your 2025 Lexus IS 350 F Sport with a new intake? Awesome choice, guys! Upgrading your intake can significantly improve your car's horsepower, torque, and even fuel efficiency. Plus, let's be honest, that throaty engine sound is a major bonus. In this guide, we'll dive deep into everything you need to know about upgrading the intake on your IS 350 F Sport, from understanding the benefits to choosing the right one and getting it installed. So buckle up, and let's get started!

Why Upgrade Your Intake?

First things first, let's talk about why upgrading your intake is a worthwhile investment. The factory intake on the Lexus IS 350 F Sport, like most stock intakes, is designed with efficiency and noise reduction in mind. This means it can be somewhat restrictive, limiting the amount of air that flows into the engine. By installing an aftermarket performance intake, you're essentially opening up the floodgates, allowing your engine to breathe easier and produce more power.

Improved Horsepower and Torque: This is the most common reason people upgrade their intake. A less restrictive intake allows more air to enter the engine, which, when combined with the right amount of fuel, results in a more powerful combustion. You can expect to see gains of anywhere from 5 to 15 horsepower, and a similar increase in torque. While these numbers might not seem huge, you'll definitely feel the difference in throttle response and overall acceleration. The improved airflow optimizes the combustion process, leading to a noticeable increase in both horsepower and torque. This translates to quicker acceleration, improved responsiveness, and an overall more engaging driving experience. The engine feels more alive and eager to perform, especially in the mid-range and upper RPMs. Whether you're merging onto the highway or tackling a winding road, the added power and torque will make a significant difference in how your car performs. This is particularly noticeable in situations where you need quick bursts of acceleration, such as overtaking other vehicles or climbing hills. The increased power also contributes to a more confident and enjoyable driving experience, making every journey a bit more thrilling.

Enhanced Engine Sound: Let's be real, who doesn't love a good engine note? A performance intake replaces the factory airbox, which is designed to muffle sound, with a less restrictive system. This allows you to hear more of the engine's natural roar, especially under acceleration. The sound is deeper, more aggressive, and adds a whole new dimension to the driving experience. The sound improvement is one of the most immediately noticeable benefits of upgrading your intake. The factory airbox is designed to minimize noise, resulting in a somewhat muted engine sound. A performance intake, on the other hand, allows more of the engine's natural sound to be heard. This creates a more engaging and exhilarating driving experience, especially when accelerating. The increased airflow and less restrictive design of the intake amplify the engine's sound, producing a deeper, more aggressive tone. You'll hear a distinct difference in the intake noise, especially when you put your foot down. This enhanced sound adds a layer of excitement to every drive, making you feel more connected to your car and the road.

Better Fuel Efficiency: This might seem counterintuitive, but a performance intake can actually improve your fuel efficiency, under certain conditions. When your engine can breathe easier, it doesn't have to work as hard to produce power. This can lead to a slight improvement in gas mileage, especially on the highway. While the gains might not be dramatic, every little bit helps, right? Improved airflow can lead to better fuel efficiency, especially during highway driving. When the engine can breathe more easily, it doesn't have to work as hard to maintain speed, resulting in less fuel consumption. While the fuel efficiency gains from an intake upgrade may not be as significant as the performance gains, they can still be a welcome bonus. Over time, the savings on fuel can help offset the cost of the intake, making it a worthwhile investment. It's important to note that driving habits play a significant role in fuel efficiency. Aggressive driving, such as frequent acceleration and hard braking, will negate any potential fuel savings from the intake upgrade. However, if you maintain a steady driving style, you may see a noticeable improvement in your gas mileage. This makes the intake upgrade a practical choice for drivers who prioritize both performance and fuel economy.

Choosing the Right Intake for Your IS 350 F Sport

Okay, so you're sold on the idea of upgrading your intake. The next step is to choose the right one for your 2025 Lexus IS 350 F Sport. With so many options on the market, it can be a bit overwhelming. Here's what you need to consider:

Type of Intake: There are two main types of intakes: short ram intakes and cold air intakes. Short ram intakes replace the factory airbox with a filter that sits directly in the engine bay. They're easy to install and offer a noticeable improvement in sound and throttle response. However, they can be susceptible to heat soak, as they draw air from the hot engine bay. Cold air intakes, on the other hand, extend the filter down lower in the engine bay, away from the heat of the engine. This allows them to draw in cooler, denser air, which can lead to greater power gains. However, they can be more difficult to install and may be more prone to water ingestion in wet conditions.

Filter Type: The filter is the heart of the intake, and it's important to choose one that offers good filtration and airflow. Reusable filters, typically made from oiled cotton or synthetic materials, are a popular choice. They can be cleaned and re-oiled, making them a cost-effective option in the long run. Dry filters are another option, offering good filtration without the need for oiling. They're easier to maintain, but may not offer quite as much airflow as oiled filters.

Material and Construction: Look for an intake made from high-quality materials, such as aluminum or carbon fiber. These materials are durable, lightweight, and can withstand the extreme temperatures of the engine bay. The construction should also be solid, with smooth welds and tight seals to prevent leaks.

Brand Reputation: Stick with reputable brands that have a proven track record of producing high-quality intakes. Do some research and read reviews to see what other IS 350 F Sport owners have to say about different brands.

Fitment: This is crucial! Make sure the intake you choose is specifically designed for the 2025 Lexus IS 350 F Sport. A poorly fitting intake can cause all sorts of problems, from leaks to poor performance.

Installation: DIY or Professional?

Once you've chosen your intake, the next step is to get it installed. You have two options: do it yourself or hire a professional mechanic.

DIY Installation: If you're mechanically inclined and have some experience working on cars, you might be able to install the intake yourself. Most intakes come with detailed instructions, and there are plenty of online resources available to guide you through the process. However, be prepared to spend a few hours on the installation, and make sure you have all the necessary tools.

Professional Installation: If you're not comfortable working on your car, or if you simply don't have the time, it's best to hire a professional mechanic to install the intake. This will ensure that the job is done correctly and that you don't damage anything in the process. Expect to pay a few hours of labor for the installation.

Maintaining Your Intake

Once your new intake is installed, it's important to maintain it properly to ensure optimal performance and longevity. This primarily involves cleaning the air filter regularly. If you have a reusable filter, you'll need to clean and re-oil it every 20,000 to 30,000 miles, or more often if you drive in dusty conditions. Dry filters can simply be cleaned with compressed air. Check the intake regularly for any signs of damage or leaks, and address any issues promptly.

Final Thoughts

Upgrading the intake on your 2025 Lexus IS 350 F Sport is a great way to improve its performance, sound, and even fuel efficiency. By choosing the right intake and maintaining it properly, you can enjoy the benefits for years to come. So go ahead, guys, and unleash the true potential of your IS 350 F Sport! Just remember to do your research, choose a reputable brand, and either install it yourself carefully or have a professional do it for you. Happy driving!
