Product Release! CorkSport Redesigned Turbo Inlet Pipe

CorkSport is pleased to announce the re-release of the CorkSport Turbo Inlet Pipe for the Mazdaspeed 3, Mazdaspeed 6 and CX7. The newest version of our turbo inlet pipe has been redesigned to provide seamless fitment with OEM or other aftermarket intake systems by replicating the fitment of the factory TIP to the intake.

This popular product maintains its ability to provide improved responsiveness and power while now providing even better fitment for customers running stock or other another non-CorkSport brand aftermarket intake.

Unlike other turbo inlet pipes on the market, CorkSport’s Turbo Inlet Pipe is constructed from mandrel bent aluminum making it a true high performance turbocharger inlet pipe. It has been designed with a downstream recirculation valve fitting to prevent turbulence backwash around the MAF sensor and avoid unnecessary check engine lights and stumbling.

During extensive testing, the CorkSport Turbo Inlet Pipe showed a 14% improvement over the stock pipe and significantly decreased airflow turbulence by removing the restrictive nature of the stock pipe with the sweeping curves associated with the mandrel bent aluminum 60mm piping used in the CorkSport pipe.

CorkSport has designed the turbo inlet pipe to be purchased as a standalone piece to compliment your current stock or aftermarket intake set-up or can be purchased with the CorkSport Mazdaspeed 3 Short Ram Intake for the best value on the market.

When combined with the CorkSport Mazdaspeed 3 Short Ram Intake, flow test results showed a 54% improvement over the stock air box and turbo inlet pipe and netted max gains in dyno testing of +25lbs of torque and +33HP.

Sold separately the CorkSport Turbo Inlet Pipe can be purchased for $109.00 and can be customized to compliment the look of your engine bay with polished or powder coated black aluminum piping and your choice of red, black or blue silicone. Purchase the CorkSport Short Ram Intake along with the turbo inlet pipe for an additional $140.00 to get the most gains from this power modification.

When Products in Development Don’t Make the Grade

Things don’t always go as planned. We begin a project thinking our customers will be able to get good results out of a new performance product only to find, when we start testing, those results don’t show up.

An example of this is the CorkSport Cold Pipe. After investing months in the development process, we are choosing to abandon the product and put our development efforts elsewhere. Focus on products that will provide our customers with the type of performance benefits that inevitably did not show up during the testing of this product.

How it all began:

After seeing the great success of our Top Mount Intercooler and the amazing benefits it offered, we wanted to find a way to give customers who chose to stick to a TMIC even more performance. Looking over the TMIC system we noticed that when the air exits the intercooler it immediately hits a wall. It exits the intercooler towards the front of the car, but just after exiting it is forced to the driver side.

Once we identified this potential air flow restriction, we decided that it would be worth it to try and expand the stock cold-pipe to provide a better path for the air to flow, as well as a larger volume to accommodate the increased flow seen with a CorkSport TMIC.

The development process:

We scanned the stock pipe into a solid model so we could improve flow and still provide a great OEM fit.

Once we had a CAD model, we noticed the access to one of the four TMIC mounting holes became covered so we added an access hole to be able to tighten down this bolt as well as provide a NPT fitting to be used with water/methanol injection.

We proceeded with some virtual testing and discovered that the flow was more even and fluid as it moved through the redesigned pipe when compared to the stock pipe. Once we felt good about the revised drawing, we took the CAD model and did a 3D print to check fitment and conduct real world flow testing.

The part fit great and looked great. We were very happy with how the project was turning out, so the next step was to do some flow tests to determine the exact gains that the redesigned part offered.

The outcome:

We were disappointed with the results. The redesigned cold-pipe by itself offered a 15% increase in flow over the stock cold-pipe. When combined with a CorkSport TMIC however, both pipes flowed the same. Since the intercooler’s max flow (still significantly higher than the stock TMIC) was less than either of the cold pipes by themselves, the redesigned cold-pipe and CorkSport TMIC only flowed 0.7 CFM more than the stock cold-pipe and CorkSport TMIC, a negligible amount.

Knowing this, we now had a big problem. Why would anyone want to upgrade this part for a negligible performance improvement? Sure the option to do methanol injection would be great for some but we didn’t think most people would be interested, even at our target of $125.

We hit the forums, Mazdaspeed Forums to be exact, and asked what they thought of the product and if they would still be interested in the product with the minimal gains seen. The general consensus was that although it was a great idea and seemed to have a lot of development and engineering behind it, they didn’t feel like it would be worth the cost or that we would see enough sales to warrant producing the part.

With this feedback, we decided to abandon the project and cut our losses on the development time and money we put into the product. Unfortunately this happens occasionally. We work on a project only to end up killing it before we reach production. It’s just the way development goes sometimes, but each and every time we can take it as a learning experience to further our knowledge about what projects may or may not be worth pursuing in the future.

We want you to feel confident that our products do what we say they will do and though it’s not an easy decision to scrap a product after investing thousands of dollars on development, when the alternative is to release a product that has no performance benefit when our customers are expecting one, the choice is simple, abondon ship.

CorkSport Top Mount Intercooler Development Process

The idea for the CorkSport Top Mount Intercooler (TMIC) was originally developed from a thread started by azmavhockey3 on the Mazdas247 forum. This idea exchange by Mazda owners on the forum lead to an in-depth development process that included several design iterations, prototype testing, sample testing, and finally production testing. The end result was the recently released CorkSport TMIC which provides solid power gains at a great value.

The following graphic demonstrates the development and testing process for the CorkSport TMIC.

Why a 3″ Core for the TMIC 

  1. Helps Maximize dissipation.
  2. Can directly bolt on the OEM cover which is designed to mate with the hood venting shroud for optimal flow.
  3. Leaves a clean look in the engine bay and covers up many of the wire and hoses near the fuel pump.
