  5. Spark Plugs After 60k Miles

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Here's a pic of all 4 spark plugs on my '14 2.0L Mazda3. Looks a bit worn, obviously, but there was no performance drop or any other indicator that led me to change these. I simply had the extra money and wanted to stay on top of maintenance. I replaced them with the suggested Laser Iridium NGK...
  6. 2014 3 Spark plugs

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Need to do my 100,000 service which is only spark plugs. Man is this car cheap to maintain.... So i would normally just go with OEM but there may be better spark plugs out there. Not too sure if it makes a difference anymore like it used to. Dealer wants $40 for each which is a rip off but...
  7. Spark plug replacement on '14 2.0

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Just realized I'm a bit overdue for new spark plugs on my '14 2.0 engine. Haven't done this myself before, but I'm trying to DIY more on this car, and hear spark plugs are easy. I can't seem to find any guides on how to do this on the Gen3. I have the service manual, which isn't super detailed...
  8. should I check for carbon deposits before changing spark plugs?

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    So it's that time for new spark plugs. It's actually 3k miles past the recommended interval (75k). My main concern is carbon deposits on the intake valves. After searching, I've learned that the best way to know you have carbon deposits is to take off the intake manifold and the best way to...

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Why are there 2 gap settings? Is it that if you adjust your current plugs, you would go with the Standard measures ? PLease explain Standard: 1.05 - 1.40 mm 0.0414 - 0.0551 in New Spark Plug (reference) 1.05 - 1.15 mm 0.414 - 0.452 in
  10. Spark knock on slight acceleration

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    2014, std.engine with 54,000 miles. I thought maybe it was a partially clogged fuel injector, so ran a big bottle of Techron fuel injector cleaner. Tank with Techron is almost used up and, if anything, knock is worse. Next trip will be to dealer. What should I expect?
  11. spark plug replacement at 55K

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    My Mazda isnt running like it used to... I've had a rougher idle and even the occasional mis at low RPM load. Its bad enough to be annoying but not bad enough to actually worry about. First I called the dealer about a carbon cleaning for the intake valves. The service adviser tried to tell me it...
  12. spark plug socket size

    2014-2018 Mazda 3 Skyactiv Discussion
    OK I give. What size of socket do you need to get the plugs out of the 2.0L? I have a 16mm, too big. Jimmied up a 14mm that seemed to fit my replacements. Even measured the replacements, 14mm. Doesn't fit the plugs in the car. Man Mazda really likes using some oddball sizes. Changed the gear...

    New Member Introduction & Forum News/Guide
    Hello, I went to change the spark plugs on my 2013 Mazda 3 sky active. However, all the sparks i bought didn't fit. I went to my local Mazda dealer and they said the Sky Active motor requires a high heat spark plug that can only be bought at the dealership. They cost approx $41 per plug. Has...

    Hi Everyone. I tried doing a spark plug change on my 2012 mazda 3 skyactiv engine yesterday. my 5/8 spark plug socket would not make contact with the spark plug. It seemed like it was rubbing up against the side of the spark plug tube in the engine block. ie. the spark plug tube in the...
