This Cobb SF Short Ram Intake is designed specifically for 2015 - 2018 Subaru STIs, though it doesn't fit the 2018 Subaru STI Type RA. It sets the benchmark for MAF - style short ram intakes. With a velocity stack, airflow straighteners, and a composite body, it delivers top - notch performance. You can use the Subaru factory snorkel to feed cold air to the SF Intake. The SF Airbox transforms the SF Intake into a cold air intake that looks and fits like an OEM part.
**Features:**
- Boosts power

- Equipped with a 4 - ply steel - reinforced silicone post - MAF hose
- Makes induction and engine sounds more audible
- The composite intake body helps reject heat
- Uses a cleanable and reusable custom filter element
- Utilizes the factory snorkel to bring cold air to the airbox
- Avoids water ingestion issues common in other cold air intakes
- Requires tuning
- Easy to install and comes with an installation guide
The Cobb SF intake system uses unique features to maintain optimal airflow for performance while reducing turbulence that can cause engine management problems. It has a custom conical cloth air - filter element, a CFD - designed velocity stack, and a special air flow straightener grid. This grid smooths the incoming air as it passes the Mass Air Flow sensor, ensuring precise readings and eliminating 'dead spots' caused by turbulence. The SF Air Box adds the benefits of a cold air intake to the SF Intake's great performance. The factory inlet directs cold air from the front grill to the SF Airbox, which encloses the SF intake, keeping hot engine bay air out. It also separates rainwater from the intake air, solving the water ingestion problems of in - fender cold air intakes.
Using this Cobb SF Short Ram Intake is straightforward. First, make sure to follow the included installation guide for a seamless setup. Once installed, you'll notice increased power and more audible engine sounds. To keep it in top shape, regularly clean the reusable custom filter element. You can do this by gently removing the filter and using a suitable cleaner as per the manufacturer's instructions. When it comes to cold air intake, the system uses the factory snorkel to draw in cold air. Just ensure the snorkel is clear of any debris for optimal performance. Remember, this intake requires tuning. So, consult a professional tuner to get the most out of your Subaru STI. Also, be aware that this intake doesn't fit the 2018 Subaru STI Type RA. Avoid driving in extremely wet conditions for extended periods to prevent any potential water ingestion issues.
