Option
Are you running an aftermarket downpipe?
Which exhaust gaskets would you like?

If you opt to send your core in first, there will be a 1-2 week turn around time once your core has been received. 

If you send your core back later, the core charge will be refunded once we receive your oem/rebuildable condition core.

This is our stock remanufactured K04 turbocharger for the 2006 - 2013 Mazdaspeed 3/6 and MPS.

This includes:
A complete rebuild, housings are cleaned extensively inside and out.

  • Refinished housing
  • Balanced rotating assembly
  • Complete gasket set(with upgraded option available)
  • 9x M10 x 1.5 Exhaust Studs
  • 9x M10 x 1.5 Nuts
  • 4x M14 Coolant copper crush washers
  • 2x M12 Oil feed copper crush washers
  • 1 Year Warranty (valid with core return)


If you are running an aftermarket downpipe, we highly advise running one of our oil restrictor bolts. This is to ensure proper oil feed and prevent over-oiling.

Gasket options: We include single-layer steel gaskets with every order, unless you select the upgraded gasket option.  We HIGHLY recommend the upgraded gaskets as they are a 5 layer multi-layer steel gasket, which will provide a much better seal than the single layer gaskets. The 5 layer gaskets have a better likelihood of being reused, unlike the single layer gaskets.

    Came in clutch!

    At 94k a rebuilt KO4 is just what I needed to get the car back on the road. I like that it came with all the hardware and gaskets. No searching around for other parts even got the oil restrictor bolt too. Nothing to complain about, it's great!

    Great product

    Great product and excellent customer service. I can see where thought was put into making the exhaust studs shorter than the OEM ones , as there's minimum engine bay space to work with. The shorter studs make life easier to install my aftermarket downpipe . The 5-layer MLS gaskets were a great choice, as they're of much better quality than the OEM.

    Worth every penny.

    Had a old smokey K04 on the speed... reached out when my motor blew and Chris got me straight! Came with all the hardware you would need. Been almost 10k later and still holding strong. Builds boost like a champ. If you're not looking to upgrade, this is the perfect turbo replacement

    Awesome

    This turbo was fantastic, the wait was well worth it to have it rebuilt. It feels quality and looked straight off the assembly line! Chris was a pleasure to work with, super communicative and always had the best of interest for his customers!
