Add Power and Get Better Gas Mileage

When most people think about purchasing an intake, they want it for the performance increases. While an intake is probably the best bang-for-the-buck modification you can make to add power and torque to your Mazda, there is another huge, but often overlooked benefit which is the improved gas mileage.

How is that possible?

The CorkSport intake uses a conical dry flow air filter with 3” outlet that is much less restrictive than the factory filter. This directly translates to better gas mileage. We have also calibrated our precision machined MAF housings and intakes to exacting tolerances and have designed them to work better and more efficiently than the factory intake system.

Where’s the proof?

We were beginning to get feedback from customers stating that they were seeing improvements in their gas mileage with the addition of the intake.

I have a brand new 2012 MS3 that is stock apart from the intake. With this new intake I have seen a my average mpg for the last 12,000 miles of normal break in driving go from 28.4 to 31 miles per gallon while now driving in a much more aggressive manner during the last 1,000 miles. I am thoroughly impressed and I hope that this information can be of use to your company and other customers. – Alex B.

To be sure we needed to control the test conditions and make our own conclusions.

After testing the Skyactiv CX-5 with the factory intake system, we showed an average of 34.0 MPG. After adding the CorkSport Short Ram intake, we have been showing 38.5 MPG average. This is a 13% increase in fuel mileage improvement just by the simple addition of intake system.

We then went a step further and did extensive in town gas mileage testing. Though the results were not as impressive, they were still substantial. The baseline with the stock intake was 29.3mpg and improved to 31.2 with the CorkSport Short Ram Intake. This is a 6.5% improvement in fuel mileage.

Of course the CX-5 SkyActiv was designed with fuel mileage in mind so getting great MPG’s in this car was not surprising. This is when we decided to take our testing to the next level and see what could be achieved on the Mazdaspeed3.

As it turns out, the Mazdaspeed3 showed similar improvements in gas mileage in the city, but significantly less on the highway. We had a 6.1% improvement in city driving and 4.4% Improvement on the highway with a peak of 33.2mpg with the CorkSport intake installed.

Some customers have seen additional increases, but the results are generally subject to how a person drives. Remember with that increase in torque and horsepower you will be more tempted to have a heavier right foot too.

What’s the Payoff?

With gas prices yo-yoing over the last couple years too, at some points, topping 4.00 a gallon here in the pacific northwest, we estimate that the intake will be able to pay for itself in around 13,000-16,000 miles. With a national average of around 15,000 miles driven per year, you can expect your intake purchase to pay off quickly and then start getting money back in your pocket from the fuel savings.

Not only does less gas mean more money in your pocket, but fewer emissions as well, so you can tell all your environmentalist friends that you are doing your part!

To recap, better mpg, more money in your pocket and you a decrease in your carbon foot print. This all sounds good to me.


Avoiding Clamp Failure Modes

As CorkSport works through R&D on any new part we are developing, we always take the time to consider possible failure modes. This ensures the final product has been thoroughly thought out and developed to avoid as many potential failure scenarios as possible.

Failure modes can come in many different forms. There are failure modes brought on by the product that have to be considered, failure modes brought on by assembly and packaging to consider, and failure modes brought about by the installation of the product. Often a failure mode can be a simple issue that may seem trivial until you sit back and consider the potential consequences. For that reason, clamp placement is a critical issue that can be easily overlooked during installation.

The Common Cause of Clamp Failures

When a part is installed that requires clamps, it is easy to consider only the aesthetics of the part. The initial reaction is to want the clamps to be even and silicone to be on properly, but there are a number of other potential hazards that need to be addressed when installing clamps.

The motor itself rocks back and forth which is particularly noticeable on a Mazda where the motor rocks a lot. Because the motor rocks but the engine bay does not, the clamps on your installed parts may move around and come into contact with other parts of the engine bay.

Notice the picture above. Everything looks good until you look closer. The clamp is actually touching the radiator hose which can be a potential failure point with the part. By simply rotating the clamp slightly so the bolt does not come into contact with the radiator hose, you can avoid the contact point and a possible problem with your vehicle.

Clamp placement is critically important with a front mount intercooler install because the clamps have the potential to contact a lot of parts in the engine bay and other pipes. When it comes to intakes, it is also very important to consider clamp placement because they are much closer to critical wiring. Simply flipping the orientation of the clamp can mean the difference between worn plastic and wiring harnesses or trouble free operation for years to come.

Avoiding Clamp Failures

Using the picture below as an example, you can see that the clamp fits well and doesn’t touch anything, but imagine if it was tightened into the stationary object. When it moves back and forth it would eventually rub through the tape and shielding and contact the wires inside. By being aware of this, we can position the clamp so it will never contact. This is something easy to do while you are installing the part, but can be a much bigger headache down the road if it is not considered upfront.

Below is another example of a clamp that is not ideally positioned. We actually have the opposite scenario here to the last example. The clamp is on a pipe that is hard mounted to the frame, while the other pipe is attached to the motor and moves. This will cause the clamp and the pipe to contact and wear against each other over time. Although both are metal, the clamp will eventually work its way through the aluminum pipe and cause a vacuum and boost leak. This means a poor running car and loss of power.

Take Time to Consider Clamp Placement During Install

Take care during your installation and avoid potential pitfalls down the road. By maintaining good clamp placement, not only will you avoid scratching the pipes, but you can avoid other potentially serious issues like boost leaks and unintentional contact with other parts in your engine bay. So remember, always keep your car safe, beautiful, and protected by maintaining good clamp placement.


Product Release! CorkSport Mazda CX-7 Airbox

We know CX-7 owners do not get a lot of attention from Mazda aftermarket performance companies and can often times be overlooked when it comes to performance parts that would otherwise be considered a standard offering for DISI engine Mazda vehicles.

With that said, CorkSport is happy to provide a little love for the CX-7 family with the release of the all new CorkSport Mazda CX-7 Air Box.

Designed specifically for the Mazda CX7, the CorkSport CX-7 Air Box for CorkSport SRI provides protection from the hot underhood air of the engine bay while adding additional access to ambient air temperatures, resulting in greatly reduced temperatures in and around your SRI for less heat soak and more power.

The CorkSport Mazda CX7 Cold Air Box for CorkSport SRI connects to the air induction scoop and can be further modified with an additional opening that can be connected to piping leading to the fenderwell.

The CX-7 Air Box is easy to install allowing customers to quickly upgrade their SRI and get the added advantage that comes with a CAI without the pressure drops inherent to longer intake piping.
