Spark Plug Replacement | 2014-2018 Mazda 3 | 2.0L

Video on changing the spark plugs on my 2015 Mazda 3. Should be the same for any non turbocharged 2.0L or 2.5L engine of this era. This motor is 2.0L.
Spark Plugs: AutoLite XP5682 (4 PK): amzn.to/3KeB7hM
Tools needed:
3/8" ratchet
Short and long extensions
8mm socket
- above items linked as a set here: amzn.to/3R5nMdh
14mm spark plug socket: bit.ly/4107Hdm
Feeler / Gap Gauge (not the same as used): amzn.to/3RZZemm
Needle nose pliers (not the same used) amzn.to/3I6P52w
Penetrating spray: see local home center.
Patience ;)
Mazda recommends changing the spark plugs every 120,000km (75,000 miles).

Thanks so much for this. I’ll be using this video next weekend to do this job. I can’t believe how much money you can save by doing your own maintenance.

just wanted to say thanks for the needle nose pliers tip. had to pull the spark plug socket off 4 times cause they were fit on so snug.

Thanks for your guide, this will be helpful once I want to do mine 😀

How tight did you tighten the plugs.

No need for dielectric grease? And if so, where?
