The Pros and Cons of OEM and Performance Intake Manifolds

The Pros and Cons of OEM and Performance Intake Manifolds


You might be asking yourself, "Which is better, OEM or performance intake manifolds?" This is a valid question, and the answer depends on your needs. Let's take a closer look at both options.

OEM intake manifolds are designed by the manufacturer of your car. They offer a stock-replacement option that can be beneficial for those who want to maintain the factory specifications of their engine. Performance intake manifolds are designed by aftermarket companies and offer increased airflow and performance.

So, which is right for you? Well, that depends on what you're looking for. If you want peak performance and don't mind sacrificing some fuel economy, then a performance intake manifold is right for you. But if you're looking for something that will give you a little more power without too much sacrifice, then an OEM intake manifold might be the better choice.

What Is an Intake Manifold?

An intake manifold is the part of your engine that distributes the fuel-air mixture evenly to each cylinder. It's usually bolted directly to the engine block, and is often one of the first engine parts to fail.

That's why it's important to have a good replacement intake manifold on hand, in case of an emergency. A performance intake manifold can help improve your engine's performance by providing a smoother contour and larger ports which allow your engine to breathe more freely.

OEM vs. Performance Intake Manifolds

When it comes to intake manifolds, there are two basic types: OEM and performance.

OEM manifolds are the ones that come stock on your car from the manufacturer. Performance manifolds, as the name suggests, are designed for improved performance. They have larger ports which allows your engine to breathe more freely, and they're often optimized for maximum performance.

One big advantage of performance manifolds is that they can often be installed without any modifications to your car. This isn't always the case with OEM manifolds, which can sometimes require modifications in order to fit properly.

The main downside of performance manifolds is that they can be more expensive than OEM ones. This is especially true if you buy a high-end performance manifold from a well-known brand. However, the extra cost is often worth it, as these manifolds can provide a significant increase in performance.

Pros and Cons of OEM Intake Manifolds

There are pros and cons to both OEM and performance intake manifolds. Let's start with OEM intake manifolds.

OEM intake manifolds are a decent job, but aftermarket intake manifolds are a better option, especially for larger t4 turbos. The stock manifold is fine up until you get into the larger t4 turbos and then it becomes a major restriction.

Aftermarket intake manifolds have the added benefit of being able to be tuned for your specific application. This means that you can get the most out of your engine by dialing in the air/fuel mixture and ignition timing to match your setup.

Now let's take a look at the cons of aftermarket intake manifolds. The main downside is that they can be expensive. Another downside is that they can be difficult to install, depending on your vehicle.

Pros and Cons of Performance Intake Manifolds

Now that we’ve looked at OEM and performance intake manifolds, let’s compare the pros and cons of each.

- OEM parts are often less expensive than aftermarket parts.

- OEM parts are usually easier to find than aftermarket parts.

- Aftermarket parts may be made with better materials than OEM parts.

- OEM parts often come with a warranty, while aftermarket parts do not.

- Aftermarket parts may offer more performance than OEM parts.

Which Is Right for You?

So, which is the right choice for you? It really depends on what you're looking for. If you want the best possible fit and quality, then OEM is the way to go. But if you're on a budget and you're willing to take a bit of a gamble on quality, then aftermarket parts may be a good option.

Just keep in mind that with aftermarket parts, you usually get what you pay for. So if you find a really cheap part, it's likely that it's not going to be as good as an OEM part. But if you're willing to spend a bit more, you can find aftermarket parts that are just as good as OEM parts.

ultimately, it's up to you to decide what's best for your car. If you want the best possible performance, then an aftermarket intake manifold is a good choice. But if you want the peace of mind that comes with knowing you're using OEM parts, then that's the way to go.

FAQs About Intake Manifolds

Q: What is an intake manifold and what does it do?

A: An intake manifold is a series of interconnected tubes that distribute the air-fuel mixture to the cylinders. The design of the intake manifold is important for the performance of the engine.

Q: What are the benefits of a performance intake manifold?

A: A performance intake manifold can improve airflow and increase power. It can also help improve fuel economy.

Q: How do I know if I need a new intake manifold?

A: If your engine is not performing as well as it used to, or if you are experiencing problems with your fuel economy, you may need a new intake manifold.


When it comes to deciding whether to go with an OEM or performance intake manifold, there are a few things to keep in mind. If you're looking for more power, then a performance intake manifold is the way to go. However, you may sacrifice some fuel economy and reliability.

OEM intake manifolds are designed for longevity and fuel efficiency, so if those are your priorities, then stick with OEM. There's no wrong answer here, it just depends on what you're looking for and what you're willing to sacrifice.
