Short Ram Intake Kits

Want quicker throttle response and a more distinct induction sound? A short ram intake kit replaces the stock air filter housing with a short tube and an open filter close to the engine. The kits here are for you if you want to improve air intake without moving the filter out into the front bumper.

What does a short ram intake do?

A short ram intake places the air filter in the engine bay close to the throttle body. The short path can give less restriction and quicker response, but the filter typically draws warmer air than a cold air intake, which pulls air from further away from the engine. Warm air contains less oxygen, so a heat shield can be relevant, depending on the car and placement.

How to choose a short ram intake

Start with fitment: the kits are typically made for a specific model and year, e.g. AEM kits for the Mazda 3 or Integra. Also check:

• Filter type – an oiled or dry filter affects how you maintain it.
• Heat shielding – see also air intake heat shields.
• Material and finish – e.g. a polished or red tube, which AEM offers in several variants.
• Sensors and hoses – the tube must have room for the mass airflow sensor and breather where the car has them.

Brands in this category include Injen, K&N Engineering, AEM Induction and Banks Power, and you will also find VO2 intake kits from Vance & Hines. Whether the part is road legal and can pass inspection depends on the product and the car, so check this for the specific part number.

Installation and maintenance

A short ram intake can often be installed with ordinary tools, but an incorrectly placed sensor or a leaking joint can cause fault codes or a rough idle. Clean or replace the filter according to the manufacturer's instructions, and check the clamps regularly. You can find separate intake tubes and other parts under air intakes and airboxes.

Frequently asked questions

What is the difference between a short ram and a cold air intake?

A short ram intake has a short tube and the filter in the engine bay, while a cold air intake typically draws air from further away from the engine's heat. Short ram kits are often easier to install but can draw warmer air.

Can I get a short ram intake approved for inspection?

It depends on the product and the car. Check the documentation and any approval for the specific part number before fitting the part to a registered car.

Does the engine need recalibrating after installation?

It depends on the kit and the car. Some kits can be installed without changes, while others can affect the mass airflow sensor readings and require the calibration to be adjusted. Check the manufacturer's instructions for your kit.
