New Product – Mazda 3 Hatchback Rear Spoiler 2019+

Enjoying your 4th GEN Mazda 3 but wanting to change up the look? Introducing the CorkSport Performance Spoiler for 2019+ Mazda 3 Hatchback. We went for an OEM+ design that incorporates the great fitment and lines of the OEM aero kit spoiler but in a much more aggressive package. Taller, longer, and with an upturned rear edge, the CS spoiler add some much needed sportiness to the look of your 3. Available in multiple finishes to suit your budget and build, the CS spoiler is a great next mod for your build! Read on for more details and check out the product listing here to purchase.

We like the OEM spoiler but were disappointed at how insignificant it looks when installed, especially when paired with the fairly aggressive OEM front lip & rest of the aero kit. The CorkSport Spoiler takes design cues from the OEM aero kit spoiler however, the design is unique to CorkSport. We started from scratch and polled the community for design opinions before settling on a final design that is both higher off of the rear hatch than OEM and extends further rearward than OEM. The design is finished off with an upturned rear edge for a great “duckbill” style look which is aggressive without being too much. You’ll be turning heads, especially when paired with CorkSport Lowering Springs and a nice set of wheels!

Fitment was equally important as aesthetics when we designed the CS spoiler. We 3D scanned an OEM aero kit wing to get the exact mounting surfaces and edge profiles so that the CS version fits just as good as OEM. We use the same mounting locations as OEM as well. This means no drilling if you’re switching from OEM aero kit to CorkSport spoiler. If you do not have the OEM spoiler you do have to do some drilling, however, Mazda pre-marks the holes for a relatively easy install! By using the same mounting locations and more adhesive mounting tape than OEM, you can be sure your CorkSport spoiler won’t be going anywhere!

The CorkSport Mazda 3 spoiler is offered in three finishes so you can choose what is best for your build. Each option uses a fiberglass base with different top layers. Regular woven carbon fiber, forged carbon fiber, and basic black fiberglass are each available. The carbon fiber options feature a UV resistant epoxy top coat for great protection from the elements and a mirror like finish. The full fiberglass option comes in a satin black coat with some light scratches and will require some finishing. We recommend some finish sanding and a final layer of paint or wrap. The shape is the same for each unit however the purchase price varies so you can really choose the best option for your build & budget.

Finally, each CorkSport spoiler comes with all the hardware and accessories needed for installation. This includes mounting bolts, washers, mounting tape, and rubber washers for waterproofing. We even include new replacement OEM Mazda clips that almost always break with removing the upper trim panel on the hatch! All of this comes with full color install instructions and great customer service & support!

2021 Turbo Mazda 3 spoiler fits with the body style well

1st Gen Mazdaspeed 3 Carbon Fiber Spoiler

Are you looking for an exterior mod that will freshen up the look of your first gen Mazdaspeed 3? Well if that’s the case then the Carbon Fiber Spoiler is the perfect part to install on your build. The Carbon Fiber Spoiler retains the OEM look with the much appreciated addition of carbon fiber. Keep on reading below for more info on the carbon spoiler.

Since the Carbon Fiber spoiler is based off of the factory Mazda piece, installation is a breeze and requires no drilling or other modifications to the hatch. We have also pinned the third brake light so that it can reuse the OEM connector with no modification to the harness needed! The Carbon Spoiler also comes with all the necessary hardware to install the spoiler so you can be back on the road in no time. Fitment with other add-on parts such as spoiler extensions or gurney flaps should work with the OEM style shape, however, we have not test fit. The same goes for GEN1 Mazda 3, the CF spoiler should fit, however, you may have a different 3rd brake light setup and/or have additional holes from the smaller Mazda 3 spoiler

Following the OEM MPS 3 design the top is carbon fiber with the bottom being a black gel coat

The CF Spoiler features a fiberglass base that is then topped off with a layer of carbon fiber on the top side of the spoiler. The underside of the spoiler is finished in gloss black and the whole thing is then coated with a UV-resistant epoxy resin to provide a mirror-like finish and the necessary protection from the elements. The two halves come together on the rear edge so there is a small seam, however, once installed, the seam all but disappears!

Cold Air Intake Systems Explained for your Naturally Aspirated & Turbo Mazda

Mazda 6 Turbo Performance Intake

Cold air intake systems, are they necessary? Are they worth the extra cost? Does it matter if the engine is turbocharged or not? Will the engine or its performance be hurt without one? We have repeatedly seen these questions on forums and social media groups regarding Mazda’s 3rd and 4th Generation Mazda 3 & 6. To help the Mazda community grow, learn about their cars, and what to do with them, we have written a blog that we hope will help shed some light on these questions and others. 

Most importantly, you will NOT hurt your engine if you use an SRI only on Turbo or Non-Turbo applications.  

What are the typical intake systems available for your Mazda? At CorkSport, we have two primary intake system setups: Short Ram Intake (SRI) System and Cold Air Intake (CAI) System. It is essential to distinguish between the two because you (the Mazda enthusiasts) will ultimately decide which system to use. 

Short Ram Intake (SRI) System

This CorkSport system consists of a filter, billet MAF housing, silicone coupler, a few clamps, and may or may not have a mounting bracket (depending on application). This system is efficient and straightforward (an unrestricted airflow path increases power). This system removes the factory airbox and snorkel. The cost is very effective for the results and provides excellent induction sounds. 

Mazda 6 Turbo Performance Intake

Cold Air Intake (CAI) System

CorkSport’s system consists of the SRI (as mentioned above) plus a heat shield or airbox designed to keep the engine bay heat away from the intake system’s inlet and helps direct cold air induction. This system removes the factory airbox and may or may not reuse the factory snorkel. The cost will be higher than an SRI due to the additional components involved and may muffle some of the induction noises but provide better heat control.

Mazda performance air intake heat shield

OK, is a Cold Air Intake System worth the extra cost and complexity? Does it do anything? Well, in our opinion, yes and no. We have tested this, and we have proven that a heatshield does improve (read reduce) “heat soak” of the intake system, BUT not in the ways most people expect. Below is some data from our 2018 Mazda 6 Turbo with our SRI and then also with our SRI + Heat Shield:

This first graph shows the vehicle idling for a period of time, much like sitting at a stoplight or in traffic. The red graph shows the SRI only, and the blue chart shows the SRI+Heat Shield. It’s pretty apparent the heat shield is helping reduce the amount of engine bay heat being ingested by the intake while the vehicle is sitting. The maximum temperature delta is approximately 15-20deg F. That’s a respectable improvement, and this lower amount of heat soak should, in theory, improve the vehicle’s acceleration from a complete stop. Now let’s look at a graph that combines idling and acceleration up to 50mph

The second graph indicates similar data for the stationary idling period, but more importantly, is what the data tells us once the vehicle starts moving. You see a small spike for both systems (this is due to the engine suddenly ingesting more air), then you see the air temp drop rapidly as the vehicle increases in speed. The vehicle’s forward motion/speed is important because that is how fresh cool ambient air enters the engine bay.

You’ll notice that both the red and blue graphs meet at the same point after the rapid cooling then have a small amount of fluctuation. In a nutshell, both the SRI and SRI+Heat Shield perform about the same once the vehicle is moving. Again, they perform almost identically once the car is rolling.

Next question, does it matter if the vehicle is turbocharged or not? Before we answer that, let’s go over the differences between turbocharged and non-turbocharged systems. 

Turbocharged

The engine is equipped with a turbocharger and an intercooler system to cool the boosted air temperatures before entering the engine. The intercooler system is required to negate the by-product of turbocharging an engine (and thus boost), which is heat. The airflow path is intake -> turbo -> intercooler -> engine.

In a turbocharged engine, the need for and use of a Cold Air Intake System is typically not deemed necessary or very useful. The turbocharger superheats the cooler air it receives from the intake before passing it to the intercooler. The boosted air exiting the turbo is substantially hotter than the ambient air temperatures in your engine bay before it enters the intake – especially true while the vehicle is moving.    

More focus is placed on performance improvements of the intercooler system because that is the primary method to cool the incoming boosted (read “hot”) airflow before it enters the engine. The use of a cold air intake system has little effect on the resulting boost air temps, so the cost-effectiveness is not great. This is precisely why the Mazdaspeed platform focuses on increasing the intake size (ingesting more air = more power), adding a larger turbo (more boost), and increasing the size of the intercooler (additional surface area for cooling) coupled with a professional tune to maximize power.

Non-Turbocharged

The engine is not equipped with a turbocharger and, therefore, does not require an intercooler system. The airflow path is more direct and does not have a cooling system built-in; intake -> engine.  

Since there is no intercooler to cool the incoming air (it’s not needed), the best way to improve air density and performance is with cooler air entering the engine directly. So, a cold air intake on a non-turbo engine can be helpful – especially in warmer climates. 

2019-Mazda-3-air-intake

Let’s Recap: 

In either turbo or non-turbo applications, a heat shield or CAI system will provide varying degrees of benefit in some driving situations. For a turbo application specifically, the usefulness of the CAI system is marginal due to the turbo heating the air it receives from the intake. Instead, investing in an SRI and performance intercooler system is a much better plan.   

For the non-turbo applications, a CAI system is a worthwhile investment because the airflow path is so much more direct, and it’s the only way to help reduce intake air temps and thus increase air density which equals power.  

We hope this has been a helpful and educational blog and lends support as you decide the right path for you and your Mazda! Thanks for tuning in!
