During the beginning of the COVID stay at home orders, I had lots of spare time and decided to develop my own hood louvers. It wasn't something I had originally intended on selling, but as interest grew I decided to start offering them for sale.
I believe most people here understand the purpose of Hood Louvers and how they work, but either way here's a brief explanation:
There is a lot of misconception about the purpose of hood louvers, and where to place them on your car for the best results. Unfortunately I see a lot of people placing their louvers in a location that will actually suck air into the engine bay, causing over heating and front end lift. The purpose of these hood louvers is to vent hot air out of the engine bay to help avoid over heating your car at the track. Venting the hot air out makes your heat ex-changers more effective(radiator, intercooler, oil cooler) by allowing more air to be pulled through them. As an added bonus it will increase the downforce(by decreasing lift) on your front end, win/win. It's important to note that the louvers need to face towards the back of the car to let hot air out, and they should run perpendicular to the air flow. You can run vents at an angle if needed, but it's not ideal.
In order to find the best location on your hood, you must analyze the high and low pressure zones. The goal is to place the vents in the lowest pressure areas if you are trying to vent the hot air out. High pressure pushes air in, which again is the opposite of what we want. To analyze the pressure, you can use a Magnahelic gauge, but we won't go to far into what that takes to do. For the simplest understanding, just remember:
High Pressure = Air going in
Low Pressure = Air going out
With all of that in mind, hood louvers are a very simple but effective solution to keep your temperatures down.
Louvers ship with hardware, cut template, and the installation guide for both the NA & NB chassis is available on my website.
I tried to come in at a lower price point by sourcing materials and labor through my contacts in the bicycle industry. (I'm a Product Manager for a bike company as a day job). I powder coat the vents and pre-bend the fins vs shipping them raw or anodized and flat, which in my opinion is a superior method, it's durable and does not fade to bronze in the sun. The shape of the vents is designed to work around the underhood bracing and electrical connectors, that's why they're a little shorter than others on the market. Lastly, I sell the parts direct through my website to further lower the cost. You aren't paying a margin for multiple companies to all get a piece.
