Reduces under-hood pressure by 50%
Dramatic Improvement in engine cooling efficiency
Decreases lift on the front of the car
Backed by data developed through pressure and flow testing
Outperforms every hood vent option tested (by a lot)
Specifically designed for the NC Miata hood
Retains hood rigidity and the use of the stock hood latch
Designed and produced in the USA
Hoods vents are a key element to improving the cooling system effectiveness. Reducing the pressure behind the radiator creates a larger differential between the front and rear of the radiator. The larger the pressure differential, the greater the airflow through your radiator. Reducing underhood pressure also cuts down on lift under the front of the car, improving downforce.
These louvers work in the lightweight factory aluminum hood to minimize cost and you do not have to deal with poor fitment of aftermarket hoods, and does not sacrifice hood rigidity so that even the stock hood latch can still be used.
This is a DIY installation part. That said, Singular MotorSports gave careful thought to ease of install from the beginning and you get a full vinyl cutting template specific to the NA or NB or NC Miata. The cut template removes the guesswork from your install, just stick it on and it shows 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. The new Version 2's come anodized in black, and can easily be painted over if you desire a different color.
What you get:
Precision waterjet aluminum louvers
Integrated gurney flap design
Aluminum rivet mounting hardware
Rubber trim to cover the cut edge for a clean look
Chassis specific vinyl cut template.
NOTE: New Version 2 of these louvers has integrated the forward gurney flap into the main louver design. For the Version 2, the front "fin" in the louvers is the gurney flap - it should be bent to vertical so that it can function correctly.
