Spark plug Bosch or Autolite

If you change the plugs; use the recommended plugs. I used Bosch Double Iridiums in my truck and they've worked good for 4 years now.

I just picked up 6 Bosch dual electrode double iridium spark plugs from autozone near me and threw them in. Fires great!

I used the gimmicky Bosch Platinum 4+ plugs which solved that problem (no more CELs) but sometimes idle is still a bit rough.

I got a sp series cold air intake and ecs performance ignition coils with bosch spark plugs. I once ran this car with 3 spark plugs for to much time and almost no oil at one point too.

Just replaced all my spark plugs that were in for 83k miles. Autolites were in and replaced with Denso twin-tip.

If it didn't misfire until you put plugs in it I would suspect the plugs are the cause.

I agree with everyone saying NGK but I would also like to recommend you do not buy an autolite if you need a substitute, they have horrible quality control.

If it is the skyactive-x be aware that the owners manual advises spark plug replacement at 40k miles and the Mazda plugs are \u00a340 each. I put aftermarket Bosch plugs in and it ran very lumpy and had to replace with Mazda ones.

Probably going to need to pull them again within a couple years. Autolites are the absolute worst sparkplugs.

If you need new spark plugs... Don't use Autolite.
