I use my car as a daily driver. I don't drive it hard. I don't redline every single time. Never hit the rev limiter. Would it be worth it to buy these spark plugs?
Just trying to have my car run well. I don't care that it says 12% performance gain or anything like that.

Thanks

It's best to use plugs recommended by Honda. NGK PZFR6F-11 or DENSO PKJ20CR-M11

 

Is it bad to use a better performing plug?

i.e ZFR6FIX-11

 

Using the wrong plugs can cause issues. I've seen it happen many times. It's best to just stick with the recommendation.

 

i usually


ngk iridiums or go to procivic.com and thats what makes my car run way better.

 

stick with factory plugs. using anything else is asking for misfire issues. only time to use a different plug is when you have modified the engine greatly.

 

I'd suggest you buy NGK Iridium IX, ZFR6FIX-11

or if you don't want to spend much, get the NGK Platinum, PZFR6F-11, these are mostly recommended for our Civics.
