Feeling like your SkyActiv powered Mazda isn’t getting the “shining” attention it deserves? Maybe you’ve already bought every CorkSport item you can, but just want more! I can’t blame you really; it’s a virus that all car fanatics fight.So here’s fuel for the fire! Introducing the aluminum crank pulley for 2.0L & 2.5L SkyActiv engines!
Manufactured from high-grade 6061-T6 aluminum, this precision machined crank pulley is sure to give you that extra level of detail you’ve been searching for. Plus it’s 100% designed and manufactured right here in the Pacific NW, USA.
This crank pulley isn’t just for looks folks, it’s got bite too!With a 68% weight reduction, compared to the OEM component, your engine is going to rev faster due to the lower moment of inertia of the rotating mass.I can’t guarantee your bum will feel the difference, but your 2.0L will.
You may also be wondering: “The OEM component is steel, will the aluminum be strong enough?” Absolutely! We’ve been testing the component on an employee car for 2 months (roughly 2000 miles) without a single issue. The accessory belts put a very small, almost insignificant, amount of force on the pulley.The real concern is the bolt that holds the pulley on, but we got that covered also, see below.
To be confident in the products we produce, we conduct FEA (Finite Element Analysis) on all applicable components.In this case it is the bolt clamping force holding the pulley on the crank.The crank pulley bolt is an M16x1.5 with a torque spec of 67-80 ft-lb.For this analysis I used 79 ft-lb which creates a clamping force of 7557 lbf.Looking at the color graph to the above, you can see that the maximum stress is ~12420 psi which is far below the material yield strength of ~40k psi.So what does this mean to you? You can (but shouldn’t) torque that bolt down to ~250 ft-lb without worrying about your beautiful new pulley being structurally damaged, but you will have to worry about getting that bolt out next time, that’s your own problem.
Add some shine to your engine bay and just a little more pep in your step.Keep an eye out for the product release in the near future! Offered in anodized black.Zoom – Zoom!

Engineered with exacting tolerances, the CorkSport Mazda SkyActiv Intake includes our precision machined MAF housing made from billet aluminum, durable dry flow air filter and custom reinforced silicone connector. In initial testing on the SkyActiv Mazda CX5, the CorkSport SkyActiv Short Ram Intake netted peak gains of +5 HP and +6 lb torque.
“Sales for Mazda’s new SkyActiv product line-up have shown tremendous potential and we have had several product requests for a SkyActiv intake,“ said Rich Harris, President of CorkSport Mazda Performance, “Our engineering staff really stepped up to the plate to get our new SkyActiv intake to market quickly in order to fully support the Mazda community.”
CorkSport has already confirmed the fitment of the single exit Mazda 3 exhaust for the SkyActiv Mazda 3 and made it available to the public and is happy to be able to add a second performance offering designed for the SkyActiv technologies developed by Mazda to increase fuel efficiency and engine output.
As with all CorkSport products, the SkyActiv Short Ram Intake comes with a two year limited warranty, full color installation instructions and CorkSport service and support. For added support, this kit also has a complete installation video.
The new addition to the CorkSport catalog is priced at $179.00. The CX-5 SkyActiv intake can be purchased separately in our newly added CorkSport CX5 catalog and the Mazda 3 SkyActiv Intake can be purchased as an option that has been added to the CorkSport Power Series 2.0 Liter Mazda 3 intake.
Product Release! CorkSport SkyActiv Short Ram Intake May 30th, 2012CorkSport
The Transportation Department published a press release yesterday (July 14, 2011) granting in full the Mazda Motor Corporate petition for an exemption of the CX-5 vehicle line from the Theft Prevention Standard and determined that the “antitheft device to be on the line as standard equipment was likely to be as effective in reducing and deterring motor vehicle theft as compliance with the parts marking requirements of the Theft Prevention Standard…”
Why do we care, you might ask? This is a key indicator that Mazda is readying the Mazda CX-5 for release in the US and based on the pattern we have seen from past models that have made an entrance into the US market, it is likely that we will see the 2013 CX-5 for sale in the US by summer of 2012.
The Mazda CX-5 will be the third model in the CX line-up, next to the CX-7 and CX-9, and will appropriately be the smallest one. Mazda said in a press release about the CX-5 that “(It) will be the first production vehicle to incorporate Mazda’s new design theme, ‘KODO – Soul of Motion’ as debuted on the Mazda SHINARI concept car, as well as the full range of breakthrough SKYACTIV technologies, including engines, transmissions, body and chassis. The CX-5 will join Mazda’s global line-up in 2012”
According to autocar, the CX-5 will be available with diesel and a six-speed manual (though the diesel is not likely to be made available in the US) and are also proposed with a double body variant 3 and 5 doors, all of which should ensure that the compact crossover not only looks good but is also fun to drive and fuel efficient.
Look out for the debut of this car at the 2011 Frankfurt Auto Show this September.
