Hey Acura enthusiasts! Are you looking to boost the performance and sound of your 2021 Acura TLX A Spec? Upgrading your car's air intake is a fantastic place to start. In this article, we're diving deep into why swapping out your stock air intake for an aftermarket one can make a noticeable difference and help you choose the best air intake for your ride. Let's explore the world of Acura TLX A Spec air intakes!

Why Upgrade Your 2021 Acura TLX A Spec Air Intake?

So, you might be wondering, "Why should I even bother upgrading my air intake?" Well, the factory air intake systems in many cars, including the Acura TLX A Spec, are often designed with cost and noise reduction in mind. This means they can be a bit restrictive, limiting the amount of air that gets to your engine. More air equals more efficient combustion, which translates to increased horsepower, improved throttle response, and, let's be honest, a more aggressive engine sound. Who doesn't want that?

Improved Performance: Upgrading your air intake can lead to noticeable gains in horsepower and torque. While the exact numbers vary depending on the specific intake and other modifications you have, you can generally expect to see an increase of around 5-15 horsepower. This might not sound like a lot, but you'll definitely feel the difference when you put your foot down.

Enhanced Throttle Response: A less restrictive air intake allows your engine to breathe easier, resulting in quicker and more responsive acceleration. This is especially noticeable in everyday driving situations, such as merging onto the highway or passing other cars.

Aggressive Engine Sound: Let's face it, the sound of your engine matters. A high-quality aftermarket air intake can add a deeper, more aggressive tone to your engine, making your driving experience more enjoyable. You'll hear that satisfying growl every time you accelerate.

Improved Fuel Efficiency (Potentially): While not always the primary goal, some air intakes can slightly improve fuel efficiency. By allowing the engine to breathe easier, it doesn't have to work as hard, which can translate to better gas mileage. However, keep in mind that this depends on your driving habits.

Types of Air Intakes for Your Acura TLX A Spec

When it comes to air intakes, you've got a few different options to choose from. Each type has its own set of pros and cons, so it's important to understand the differences before making a decision.

Cold Air Intakes (CAI)

Cold air intakes are designed to draw cooler air from outside the engine bay. Cooler air is denser and contains more oxygen, which leads to better combustion and increased power. CAIs typically place the air filter lower in the engine bay, away from the engine's heat. However, this can also make them more susceptible to water ingestion in wet conditions. Guys be careful!

Pros:

• Potential for the greatest power gains.
• Improved engine sound.

Cons:

• Higher risk of water ingestion.
• More complex installation.

Short Ram Intakes (SRI)

Short ram intakes, as the name suggests, use a shorter intake tube and place the air filter within the engine bay. This makes them easier to install and less prone to water ingestion. However, because they draw air from within the engine bay, they can sometimes suck in warmer air, which can slightly reduce power gains compared to a CAI.

Pros:

• Easy installation.
• Lower risk of water ingestion.
• Improved engine sound.

Cons:

• Potentially smaller power gains compared to CAI.
• May draw in warmer air.

Ram Air Intakes

Ram air intakes are designed to capture the outside air stream to force more air into the intake. This design is more complex than Short Ram Intakes or Cold Air Intakes. The functionality is to use the vehicle's motion to increase the static air pressure within the intake manifold on an engine, thus allowing a greater massflow through the engine and increasing engine power. The ram air intake is efficient only at medium and high speed. This design is more popular for racing.

Pros:

• Potential for great power gains at high speed.
• Improved engine sound.

Cons:

• Complex design.
• Inefficient at low speed.

Hybrid Intakes

Some manufacturers offer hybrid intakes that combine elements of both CAIs and SRIs. These intakes try to strike a balance between performance, ease of installation, and risk of water ingestion. They might, for example, use a heat shield to protect the air filter from engine heat while still drawing air from within the engine bay.

Pros:

• Good balance of performance and ease of installation.
• Reduced risk of water ingestion compared to CAI.

Cons:

• Power gains may not be as high as a CAI.

Factors to Consider When Choosing an Air Intake

Okay, so now you know the different types of air intakes available. But how do you choose the right one for your 2021 Acura TLX A Spec? Here are some key factors to keep in mind:

Performance Goals: What are you hoping to achieve with your new air intake? Are you looking for maximum horsepower gains, improved throttle response, or just a better engine sound? Your goals will help you narrow down your options.

Driving Conditions: Do you live in an area with frequent rain or flooding? If so, a CAI might not be the best choice due to the risk of water ingestion. An SRI or hybrid intake would be a safer bet.

Installation Difficulty: Are you comfortable working on your car, or would you prefer to have a professional install the air intake? Some intakes are easier to install than others, so consider your skill level and available tools.

Budget: Air intakes can range in price from a couple of hundred dollars to several hundred dollars. Set a budget before you start shopping so you don't overspend. You don't need to break the bank to get a quality air intake.

Brand Reputation: Stick with reputable brands that have a proven track record of producing high-quality air intakes. Read reviews and ask for recommendations from other Acura owners.
