  • Works perfectly in my 2014 Mazda 3
Size: (Pack of 4)
The spark plugs arrived pre-gapped, and fit perfectly in my 2014 Mazda 3. Since installing the new plugs my car has performed noticeably better, which makes the price of these plugs worth it. Since the plugs arrived pre-gapped, installation was a breeze.

  • Good plugs
Size: (Pack of 4)
Fit my 2017 accord perfect. Car runs smoothly and a little more mpg. 6 month later plugs are still really good. 9 month later still running great! 2 years later still going strong!

  • Worked great for 2013 Mazda CX-5
Size: (Pack of 4)
I got a cylinder misfire for my 100K mile Mazda CX-5. I thought I should replace the spark plugs either way so I went for these. Went in nice and easy. I'm still getting the misfire code so the journey continues but these spark plugs work good.

  • Not worth it get OEM
Size: (Pack of 4)
Put these in my 2015 WRX, ran fine for 10-15 miles so I tried some relatively hard driving after that I idled like a freight train. I thought it was my tune but after I started stalling in N i knew it was the plugs. The images show the wear after less than 100 miles. I gapped these by hand so maybe if you are better at gapping you will do better with these than I did but this was absolutly rediculous. ... show more

  • Make sure to gap
Size: (Pack of 4)
3 of the 4 were at the correct gap, one was double. Make sure to check before installation.
