Backed by data developed through pressure and flow testing
Outperforms every hood vent option tested (by a lot)
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 are the first hood vents specifically designed for the miata hood through real world testing and which retain hood rigidity and use of the factory hood latch and prop. Most DIY or aftermarket vents that have been grafted onto Miata hoods in the past do not offer these features.

Singular MotorSports carefully tested their design on the Miata. They started by investigating the pressure and airflow of the stock hood and then tested a number of existing venting options. They used the best performing vent they found as a benchmark and set out to beat it with a new design from the ground up.

The result is a louver system including gurney flaps that reduces the pressure under the hood by a staggering 50%, fits NA and NB hoods with placement tailored to each model. These louvers work in the lightweight factory aluminum hood to minimize cost and you avoid dealing with the poor fitment of aftermarket hoods. These do 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 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 INSTALL NOTES: Here is what you get in the box, including template.

Start with positioning the included template on the hood as shown below:

Louvers are pre-cut but need to be bent as shown here:

Result after bending looks like this:

After painting or powder coating they can look like this:

Cut and attach.

Installed they look like this:

Wanted to say thanks. The exhaust system fit perfectly, no drone at steady throttle, but a nice sound winding thru the gears. And it does sound a lot like my old Alfa. The Racing Beat lowering springs are just right. Appreciate the tech advice and the service.

Purchased the RS Max Power header and midpipe. THESE ARE TRUELY A WORK OF ART! CRAFTMANSHIP IS TOP NOTCH!! SITE PICS DO NOT DUE JUSTICE TO THESE ITEMS! I recommend Brian's site to ANYBODY with a Miata/MX 5. Brian and Co have taken a great automotive platform and elevated it to it's FULL POTENTIAL!
