#1 HPS Black Short Ram Air Intake Kit

  • Manufacturer: HPS
  • Features: HPS Performance Air Filter
  • Power Gain: 11hp
  • Compatibility: Lexus IS300 (2000-2005)

To start the best IS300 intakes, we present to you HPS and their short ram air intake kit. Short rams are designed to have shorter intake pipes, reducing the airflow restrictions by eliminating other parts like the resonator and silencer box.

This design is what HPS did to their intake system; that’s why it’s capable of producing an extra 11hp for the benefit of your Lexus IS300.

The HPS short ram intake’s piping utilizes a 2.75” mandrel-bent aluminum alloy piping with minimal to no restrictions compared to the stock intake pipe.

This piping is then connected to an HPS performance air filter that sieves the air, filtering all of the contaminants that may harm the engine. The air filter that HPS Black Short Ram uses is washable, reusable, and requires minimum maintenance.

Since short ram intakes are close to the engine, there must be something to fend off the heat that comes from the engine. HPS designed a powder-coated heat shield to do just the thing.

This heat shield is integrated with a fresh air scoop to maximize the cool air that the short ram intake sucks in. Overall, the HPS short ram intake is an affordable air intake system for those who want power benefits, especially in the high revs.

So what makes the Takeda Stage-2 noteworthy? The intake’s 3” tube guarantees an improved volumetric flow, which means more air for the engine. The engine needs all of the excess air that it needs, especially cold-air.

Getting an Aftermarket Intake System: Is It Worth It?

Craving some extra power for your car is a natural gearhead phase. Getting this extra power, however, is now the problem.

How can you add some good horsepower to your vehicle? There are some options that you can consider, for example, getting a turbocharger for your car.

It’s a great option; however, if you don’t want an overkill in extra horsepower, then opting for an intake system is a great idea.

Aftermarket air intake systems can make your car more powerful, give it better gas mileage, and add some character to the vehicle by making the sound under the hood louder and more aggressive.

On top of that, most air filters included in the available intake systems have low-maintenance air filters. So, is getting an aftermarket air intake system for your car worth it? Absolutely!

The Lexus IS300 is one of those cars that employ aftermarket air intake systems broadly. Since it has the 2JZ engine, why not crank the engine up a notch and make it slightly more powerful?

You can do such a thing through the use of an intake system. Either a short ram or a cold-air intake will do the trick.
