Maximize your stock fuel system while protecting your engine with the CorkSport MZR DISI Max Flow Fuel Pump Internals.

With well over 2 years of research and development, you can count on CorkSport to bring innovation to the high pressure fuel pump on your Mazdaspeed.

With hardening surface treatments, high strength coatings and a machined tolerance that is the best on the market, our pump internals are ready to give you the most performance available for your dollar.

These pumps are precision machined, then treated, then coated and then machined again for a perfect fit and an ultra-high efficiency. That difference in the real world is going to be higher horsepower capability, safer air/fuel ratios and the ability to go that much further in the quest for power without worrying about fuel supply.

Fitment Inspired

We know modifying additional components to install a new performance part can be a real PITA; we worked hard to design a performance intake manifold that does not require extensive modification to use. The CS IM installs nearly identical to an OE IM plus difficult to access hardware locations on the flange have been clearanced for improved installation.

The following components are in OE location and install like OE:

  • Fully Machined Installation Tools Designed to help provide the most trouble free install on the market (the keeper tool even turns into a bottle opener for your keychain).
  • High Rate Spring A higher rate spring is included in our kit for increased reliability and efficiency.
  • Designed Specifically for Mazdas The ONLY pump internals on the market designed by a Mazda performance company for the Mazda MZR engine, including Mazdaspeed 3, Mazdaspeed 6 and Turbo CX7.
  • Precision tolerances and improved efficiency 50% larger than the OEM pump internals for increased fuel volume flow.
  • Required Hardware Anodized Aluminum Installation Sleeve and Retaining Hardware included.
  • Tough Aluminum Case For storing your factory internals or anything else that is legal.
  • CorkSport Service and Support: Receive a two year limited warranty, full color installation instructions, all of the needed installation hardware and knowledgeable telephone support.

    This definitely took a little longer to install them I thought but the results are incredible. The car runs much smoother, power kicks in quicker and is well distributed across the RPM's. Noticeable increase in power and now I have the piece of mind of finally having this and knowing that my car is ready for the big bad downpipe. Stop wondering if you should buy this and just do it! It's worth it and you need CORKSPORTS version which is the absolute best! Thank you Corksport!
    These internals are just as good, if not better than the popular Autotech and come with easy to read and follow instructions. Great pressure at WOT and I'm completely confident in this part. They sold out when I ordered mine and I was worried I wouldn't get them in time for dyno day at the local Mazda shop. I emailed Brett and told him this, and he reassured me they would make it in time. A few days later I get an email with the shipping tracker, and they had upgraded my shipping to priority at no extra charge. Amazing customer service, I will continue to spend all my money at Corksport! Thank you guys!
    a bit expensive especially for how small the parts are, but feels so much more smoother and responsive saw a max fuel pressure of 2059psi on my access port, max i hit before was 1857psi , took me a hour and 15 to do it and clean out the crap from the pump put a clean oil film on everything and went together smooth
    If you plan on modding your engine in any way, even if it's only a Stage 1 CAI, I recommend purchasing CorkSport's fuel pump internals. They are the gold standard and cheap insurance.

    I've got 10k miles on mine with no issues and I have the confidence of knowing I can supply 1800+psi at WOT all day long.

    The install was easy with two caveats:

    1) A giant bench vise and breaker bar are very helpful.

    2) On my car (2006 MS6), during removal, I could not get the fuel pump to clear the bottom fuel line no matter how hard I tried. I ended up finding a clamp securing the line to the engine block that needed to be loosened allowing me to lower the line a little so the fitting on the bottom of the fuel pump would clear. We're talking less than a millimeter here, but it would not come out for me without this step.

    Finally, FWIW, I noticed zero noise difference between the OEM and CS internals.

    As always, great job CorkSport!

    Worth the price buy over all other brands. I had an autotech already installed not my choice obviously. I can speak first hand that corksport is better I logged a 4th gear pull WOT with the autotech results were 1,856 psi in the fuel rail. I ran the same test with corksport and the results were a peak of 2,001 psi in the fuel rail. Corksport internals hands down have a higher flow and send more fuel to the engine. This means more power and safer to run higher boost levels.
    This is an addition that I didn't think I really needed, as I am not interested in doing any tunes or any of the mods that I read about on the forums, but I believed someone on a very rude and crude forum that the first mod for a Gen 2 should be to replace the fuel pump internals. So, OK, it was the 4th or 5th addition but WOW, I didn't expect the drivability differences these internals have made! My car now drives in such an amazing way. I am a Pastor, not a technician, so I will likely use the wrong terminology, but let me just say that from the start it takes less gas to start from a stop, and the acceleration is much smoother and more linear.

    I am confident that following this advice is a good move on my part.
    As with all CS products that I have bought the quality is second to non. Packaging is fantastic and between the YouTube install video and the detailed colour instruction the installation is easier then it looks. Took me about 2 hours including putting all my tools away. Take your time and this is a pretty straight forward install. Took it for a little drive and you can tell right away how much smoother the car is. Thank you CS for all that you do.
    These parts are a NECESSARY evil on our engines. Buy them from corksport to ensure quality and quick shipping! Was everything I expected and more. I would recommend this upgrade to anyone looking to mod. As in do this first and be smart. They are expensive but well worth it. Not to mention is comes in a nice case (as do most CS products) as well as the tool used to install it functions as a keychain bottle opener. Always love cracking a cold one with my HPFP tool.. because its badass bro. Buy it
    Excellent quality, best features on the market, and as always good tech support from the guys had a technical question and they followed up with me right away.
    They're the best in the game, can't even compare how dedicated these guys are to other manufacturers. It makes me question why cp-e,cobb, and jbr didn't even make their own fuel pump internals. It's quality every time I purchase something here. They include everything you need and need to know.

    I'm assuming that with the tappet already mated to the collar there is no further seating required? This is the only step in the process that differs from the instructions.

    Hello, I installed the corksport internal in a brand new hitachi pump in my gti mk5 fsi engine 2008. The stock pump works perfectly fine, however with the corksport internals the car would have difficulty to start, like if the pump is not primed, and when the car does start the ecu throw the code p2293 Fuel Pressure Regulator 2 Performance code, and the car appears to be a limp mode. No boost no power. Apparently the car is experiencing fuel starvation. When I put back the stock internal in the pump, everything is normal. Any suggestion? Should I try with the stock spring?
