  1. Full Aluminum Race Radiators

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Hello All, Nobody makes a full aluminum race radiator for the gen 3, so I am sizing up off the shelf options for an adapt-to-fit setup.

  2. Condensor / Radiator fan not running

    2010-13 Mazdaspeed 3 Engine and Performance
    2010 3 hatch 2.5 I noticed the fan not running when the a.c. was on, so I eventually figured out that the ground cable assembly was bad. I also put a ScanGague2 in so I had a temperature gauge. Again the fan wasn't working, so I ordered a Four Seasons brand from Rock, and installed it last...

  7. How do I fix this?

    2010-2013 Mazda 3 Engine and Performance

    2010-2013 Mazda 3 Engine and Performance
    Gauge install woes continue... After the heater hose adapter didn't work out, I purchased the sender adapter from Prosport, 32mm diameter. I did some research before and found that the radiator inlets were 33mm, so no problem right? Well I've been doing more research, and have been finding...
