Is Getting a Performance Intake System Worth It?

Well, is it? The short answer is yes. Getting a performance intake system to replace your stock intake system would be worth your while. As you see, the OEM intake system is made to be more restrictive. It provides the standard amount of restricted airflow and minimizes noise for the fresh out-of-the-factory car. 

There are three main reasons why you should ditch the stock intake system and replace it with a performance intake system.

  1. The Stock Intake System Is Too Restrictive

The OEM intake has too many twists and turns, not allowing the air to go into your engine as efficiently as possible. It is designed that way to minimize the noise that the intake system creates. All of those restrictions don’t allow cold air to go inside the engine, and thus preventing the engine to burn the air-fuel mixture efficiently.

Getting an aftermarket performance intake system will relieve all of that restrictive pathing. Aside from that, this new addition to your car offers you a much more easy-flowing path, mandrel-bent to make sure all of those pipe losses are minimized.

  1. The Sound Under the Hood Is Too Quiet

Don’t get us wrong: a quiet car is nice, especially if you want to be a low profile casual driver. However, if you want to stand out while driving your Nissan 240SX S13, you need to release the reigns off of your horses and let them neigh as loud as possible! 

By replacing the OEM intake system of your Nissan S13, you allow it to freely produce a wonderful sound that indicates that the engine is breathing better. It’s the little things in life that count, right?

  1. The Airbox is Poorly Misplaced

The airbox is usually located inside the engine compartment, and frankly, that doesn’t do your car any good. The OEM airbox tends to suck up hot air, and the engine would have a bad time burning the fuel as efficiently as possible. 

Aftermarket performance air intake systems are placed outside the engine compartment, allowing cooler air to be sucked up into the engine. The cooler the air, the more oxygen it has. And the engine likes that!

  1. The Air Filters Barely Filters

The filters OEM air intakes use resembles cheap paper, and it does what it is expected to do: to filter the air. However, due to its make, it restricts the air even more and prevents optimum airflow.

The air filters used by performance intake systems manufacturers these days are innovative, durable, and low maintenance. Usually, they offer air filters that are washable and don’t require oil to function. This permits better filtration, making the air going inside the engine free-flowing and contamination-free.

  1. You’ll Get Tons of Benefits From a Performance Intake System

By getting your hands on a new performance intake kit, you’re guaranteed to have an increase in horsepower, a better throttle response, and an improved fuel economy. These are such useful benefits especially if you’re the Nissan 240SX S13’s performance capabilities. 

There’s a lot of benefits from replacing your stock intake system with a new one, preferably a performance intake system. It’s affordable, reliable, and most of all, it delivers the performance aspects that it promises.
