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.

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.

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 templateINSTALL 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:

RE: RoadsterSport Stainless MX5 Miata Midpipe Part# 60-1328: I love the mid-pipe!! Not only is it beautiful, but it makes the sounds coming out of the 'race single' exhaust even better. The two go well together, and it mellows the decel drone a lot. I'm very happy with my purchase.

After reading many other positive reviews on both the GWR and Miata forums I finally decided to buy this product. My main concern for many months was whether or not I was up to the task of installing the header. But with the excellent instructions on Brian's forum as well as several Miata forum threads it turned out easier than I expected. After receiving notice that the header would arrive on a Friday afternoon, I began the disassembly process. After about 3 hours I had the stock manifold out. Later that afternoon the new catted header arrived right on schedule. And it is a thing of beauty. I opted for the stainless version. Installation on Saturday morning took another 3 hours, although I could have shaved some time off of that but I was actually enjoying the process of double checking torque values and cleaning up my engine compartment. I already have the GWR catted midpipe, so that connection was a snap. I put everything back together, reconnected my battery, and went for a drive. NO CODES! Nice throaty sound with my RSII muffler, and a significant boost in power and low/mid torque. Another happy camper here. I since have added a M-E tune and I feel I have realized all of the gains that Brian has achieved on his 2012 project Miata. I've put several hundred miles on my Miata since the install with zero problems. This is the car that Mazda should have built all along. Thanks Brian.
