Description

Hood louver system for the 2008-2014 Subaru WRX and STI.

Why vent your hood?

This is a key element to improving the cooling system. Reducing the pressure behind the radiator and other heat exchangers creates a larger pressure differential between the front and rear of those cooling components. The larger the differential, the greater the airflow. Reducing under-hood pressure also cuts down on lift under the front of the car – thus improving downforce.

Developed for Motorsports

We designed our first WRX/STI hood louver system for the Jager Racing STI. This 600+hp Time Attack car has massive cooling needs and the team knew they needed well-designed and functional vents. Since then our hood louvers have become known in the Subaru racing community for extracting the greatest real world improvements in cooling and performance, far exceeding airflow of other hood vents and vented hood options.

Features of the kit

Our kits are designed with actual airflow testing and pressure mapping on the car to ensure maximum performance. Other generic/universal vents simply can’t perform as well. We also believe that hood venting doesn’t need to look like an industrial afterthought on the car – which is what you get with most options out there. We design the shape of our vents to work with the surrounding body lines for the specific car model so the car looks as good as it performs.

This is a DIY part. That said, we’ve thought about ease of install from the beginning and you get a pair of vinyl stick-on templates. The templates removes all of the guesswork from your install – just stick them on and they you where to cut. Also included is rubber trim that fits around the circumference of the holes, making it easy to achieve a clean and finished look.

The louvers ship flat (unbent), you bend the fins when you receive them, and you’re free to finish them however you prefer. Powdercoat will have great longevity, but even simple Rustoleum flat black looks fantastic. Customize your look – we have customers who have anodized, plasti dipped, and even hydro dipped their louvers! Another great tip is to go down to your local NAPA and they can paint match to your car’s color and mix it up in a spray can for just a few dollars.
