Guys, we want your feedback on a project we’ve been working on for the past year.
We’ve shown glimpses of our Mazdaspeed intake manifold from time to time, including the one below when we had it installed on Barett’s Mazdaspeed 3, which popped up on our Facebook page—on April Fool’s—while it was being tested.
This manifold is designed to be a bolt-in. It’ll work with the stock throttle body, stock intercooler, stock you-name-it. This means if you’ve upgraded to a front mount intercooler, it’ll also work as it keeps the OEM throttle body location.
We’ve been through a few iterations of the intake manifold, and below is a picture of the latest version. We’ve changed several things in the design from the last test version, including individual ports for the runners to install meth injection.
In our testing, we’ve found spool to be 200 rpm sooner with the manifold installed. This has been shown on a 1st gen Mazdaspeed 3 equipped with the CorkSport turbocharger and a 2nd gen Mazdaspeed 3 with a GT35r installed.
We also had a peak increase in power of 17 horsepower at the wheels on the 1st gen Mazdaspeed 3 in back to back testing with the manifold.
So. This is where you the Mazdaspeed owner comes into play. We want to know: Would you buy this if we made it? Tell us your thoughts, and if you are interested, shoot us an email so we can keep you updated.
Cheers,
CorkSport

I was able to get a Relentless Customs manifold for 1/3 of the price you are asking. The one I got was polished as well. With an option for port injection I can see it going for $650ish but $725, you’re approaching BT territory.
A ported manifold is not a good comparison against what we are working on bringing to the market, it may be good enough which is fine for some people but it does not correct the base design of the manifold.
Will this help with the #3 cylinder issues?
It will address the un-even airflow from the intake manifold.
I’m definitely interested if it has even air flow with no detrimental side effects (cold starting, low rpms, light throttle input), and can fit with oem fmic designs.
I’m interested as well,I want to keep my TMIC.
What is the eta on this?
The manifolds are moving forward. We are doing long term testing currently.
Exactly what I was looking for. The JMF intake mani is ugly as all hell, and the relentless customs PNP “stock” mani is boring. This looks like a good combination of design and performance
I’m interested.
why no port injection compatibility like the other competitors?
We went for a more OEM look on the manifold with better flow. Why be like other companies? We have several manifolds out in beta testing now which we are collecting more data on the final design.
Come on I need one know!!!!! Please?
We are working on them as fast as we can.
When you say 17 horsepower at the wheels, was this on a full stock 1 gen mazdaspeed 3? I really like it. Looks stock. Perfect.
Please tell me it will fit on the MS6.
It will fit. We have a BETA unit in a Mazdaspeed 6.
i have the 725 when can i buy it
We have the beta units in the field and we are working on production units. We will post up when we expect to have them available for sale.
Awesome. I’ll be saving up for it.
i hope you offer the tb on the opposite side(or it be a plate that you have a similar looking blocker for so that either side can be the TB side(or goodness, maybe both!!!) because it would be nice to have a blow through IC, i don’t get how a fmic is benefitted by the silly stocklike TB placement, maybe the kits out so far? But for the ms6 there hardly are any(and ones that are out are discontinued), I would rather the TB be on the opposite side of the IM so that ablow through intercoler core can be used, and not have more pipe than a plumbing factory. Or, and this is just wishful thinking,how about a manifold with optional ability to have water to air core cylinders by laminova inserted into it for supplemental cooling, or if you really want to give the mzr motor a speed-gasm, how about showing it the same love some miatas get, in the form of a roots blower inside the mani…. nothing like constant positive displacement , but I have as much hope for that, as actually winning the lotto… maybe i can sell a kidney?
Any updates?
We are working on quality improvements of the manifolds currently.
Will you be taking core charges on this item?
This is not a stock manifold, it is a new casting so we would have no interest in the OEM intake manifolds.
I really hope that you would consider to include the option for Meth Ports to all runners and a final cure all for even air flow across all ports…..Looking forward to add this to my MazdaSpeed 6. Which already had the CorkSport FMIC and CorkSport complete Exhaust set up
Make it flow, add some color options, & it will sell.
Any updates on this Manifold?
Can you provide flow data? What would be the total percentage of flow imbalance?
Any updates for when this will be ready? really excited to get this!!!
What Paual (above) doesn’t realize is that this flows WAY more than his Relentless ported IM, and has less than 1% flow imbalance between cylinders, again, something his ported IM doesn’t come close to.
Another huge benefit of this is it will be compatible with a TMIC.
Is vtcs deleted on this intake mani?
Yes it is.
Will the throttle body be in the same position like the oem
I will by one if it also fits with the aluminum radiator
The manifold keeps the throttle body in the OEM location.
Yes it fits with the thicker CS radiator.
So how are we doing on this?
Ready to go with this manifold. Must be getting tired of everyone asking when it will be ready ?. Ready when it is. Very glad it works with the FMIC.
Am interested In this manifold plz let me know when it’s about to buy!
We have the first batch in production.
Ready and waiting for manifold goodness here in Australia.
Please provide me with adinitional information to the supplied email for release.
Will it come for meth injection?
No port injection?
Will you include new gaskets with the kit (IM/Head and TB)? Just cancelled my order for another aftermarket manifold, based on your comment above that the first batch is in production as of 9/26/16
Ill be definitely buying one of these bad boys. Keep us up to date 🙂
will it fit a bigger TB like from the chrysler 300 3.6l? I think it was like 74 or 75mm
So when should I plan one giving you guys my money for this? I need this manifold… Seriously.
Is it possible to get it without the tmic option? and a central single, maybe dual, meth location? How is fitment and install, eg sensors in stock locations? I had some “easy bolt-on” parts that had horrible fitment. I’m seriously interested but I will say that I like the look of the JMF more, but reading that it has fitment issues scares me.
One last thing, dyno please with mod list (before and after would be awesome).
When can I get it?
Do you do anything to address the MIL from removing the VTCS?
