Hey car enthusiasts! Are you looking to upgrade your 2021 Lexus IS350 F Sport? One of the best ways to enhance its performance and sound is by upgrading the intake system. Let's dive into everything you need to know about choosing and installing the perfect intake for your ride. We’re talking about better airflow, improved horsepower, and that sweet, sweet engine roar that makes every drive a thrill. So, buckle up and let’s get started!

Why Upgrade Your Lexus IS350 F Sport Intake?

Upgrading your Lexus IS350 F Sport intake isn't just about making your car sound cool (though that's definitely a perk!). The stock intake systems in many vehicles, including the IS350, are designed with compromises in mind. Carmakers prioritize things like noise reduction and cost-effectiveness, which can restrict airflow to the engine. By installing an aftermarket intake, you're essentially unshackling your engine, allowing it to breathe more freely and perform at its peak.

Performance Gains

Let's talk numbers. While the exact gains will vary depending on the specific intake you choose and other modifications you've made, you can generally expect to see an increase in horsepower and torque. We're often talking about gains in the range of 5 to 15 horsepower. That might not sound like a ton, but you'll definitely feel the difference, especially in throttle response. Your IS350 will feel more eager to accelerate, making those merges and overtakes a breeze.

Enhanced Sound

Okay, let's be real – the sound is a big part of why many of us upgrade our intakes. A good aftermarket intake will replace the muffled, stock sound with a more aggressive and throaty roar. You'll hear the engine sucking in air, adding a visceral thrill to every drive. It’s a sound that tells everyone around you that your IS350 means business.

Improved Fuel Efficiency?

While performance and sound are the primary reasons to upgrade, some drivers also report a slight improvement in fuel efficiency. The theory here is that a less restricted engine doesn't have to work as hard to produce power, potentially leading to better gas mileage. However, this is highly dependent on your driving style. If you're constantly flooring it to enjoy that new intake sound, you probably won't see any fuel savings!

Types of Intakes for Your Lexus IS350 F Sport

When it comes to choosing an intake for your 2021 Lexus IS350 F Sport, you'll generally encounter two main types: short ram intakes and cold air intakes. Each has its own pros and cons, so let's break them down.

Short Ram Intakes (SRIs)

Short ram intakes replace the stock airbox with a filter and a short tube that sits within the engine bay. The main advantage of SRIs is their simplicity and ease of installation. They're generally less expensive than cold air intakes, and you can often install them yourself with basic tools. The downside? They draw air from within the engine bay, which can be hotter than the air outside the car. Hotter air is less dense, which can slightly reduce performance compared to a cold air intake.

Cold Air Intakes (CAIs)

Cold air intakes, on the other hand, are designed to draw air from outside the engine bay, typically from the fender well or near the front bumper. This allows the engine to ingest cooler, denser air, which can lead to greater performance gains. CAIs are generally more expensive and can be more difficult to install than SRIs, but many enthusiasts feel the performance benefits are worth the extra effort. Keep in mind that some CAIs can be susceptible to water ingestion in heavy rain or flooding, so it’s essential to choose a reputable brand and install it correctly.

Considerations

Before you make a decision, think about how you use your IS350. If you are wanting to maximize performance, especially in hotter climates, a cold air intake might be the way to go. If you live in an area with heavy rain, research CAIs that have splash shields or bypass valves. On the other hand, if you just want a bit more sound and a small performance bump without a lot of hassle, a short ram intake could be a great choice.

Installation: DIY or Professional?

So, you've picked out your new intake. Now comes the question: should you install it yourself, or should you take it to a professional? The answer depends on your mechanical skills, your comfort level, and the complexity of the intake system.

DIY Installation

Many short ram intakes can be installed with basic tools and a bit of patience. If you're comfortable working on cars and have experience with basic hand tools, you can probably tackle the job yourself. There are plenty of online tutorials and videos that can guide you through the process. Just be sure to follow the instructions carefully and double-check all your connections.

Professional Installation

Cold air intakes can be a bit more challenging to install, as they often require removing parts of the bumper or fender liner to route the intake tube. If you're not comfortable with this type of work, it's best to leave it to a professional. A qualified mechanic can ensure that the intake is installed correctly and that all connections are secure. Plus, if anything goes wrong, you'll have someone to blame (and hopefully, a warranty to back it up!).

Tools You Might Need

Whether you're doing it yourself or hiring a pro, make sure you have the right tools for the job. This might include:

• Socket set
• Screwdrivers
• Pliers
• Wrenches
• A drill (for some CAIs)

Maintaining Your New Intake

Once you've installed your new intake, it's essential to keep it clean and well-maintained to ensure optimal performance and longevity. Most aftermarket intakes use washable and reusable filters, which need to be cleaned periodically. Here's how:

Cleaning the Filter

1. Remove the filter from the intake tube.
2. Tap the filter gently to remove any loose dirt or debris.
3. Apply a specialized air filter cleaning solution (available from most auto parts stores).
4. Let the cleaning solution soak in for the recommended amount of time.
5. Rinse the filter thoroughly with clean water, making sure to remove all traces of the cleaning solution.
6. Allow the filter to air dry completely before re-oiling (if necessary) and reinstalling it.

How Often to Clean

The frequency of cleaning will depend on your driving conditions. If you drive in dusty or dirty environments, you'll need to clean the filter more often. As a general rule, it's a good idea to clean your filter every 15,000 to 30,000 miles.

Conclusion: Is an Intake Upgrade Worth It?

So, is upgrading the intake on your 2021 Lexus IS350 F Sport worth the investment? In my opinion, absolutely! You'll not only unleash a bit more power and improve throttle response, but you'll also enjoy a more aggressive and engaging engine sound. Plus, it's a relatively easy and affordable modification that can make a noticeable difference in your driving experience. Whether you're a seasoned gearhead or just looking to add a little excitement to your daily commute, an intake upgrade is a great way to personalize your IS350 and make it truly your own.

Happy driving, and enjoy that sweet intake sound!
