Default autolite platinums in civic dx, get rid of them for ngk?

Do autolites just not work in Hondas? I posted a question about poor engine performance earlier and then thought about it, when I bought new plugs the store didn't have NGKs so they said use autolites, I've never used them before and was wondering if they could impact engine performance that much?

anytime you run an aluminum head, regardless of make in my opinion, ngk is the plug to go to, and not the platinum unless you have a hotter spark system.

I just put autolite platinums in my cavalier and my car did not like them at all! It was idling rough and randomly misfiring so I put the old spark plugs back in which are also autolite but they are the extreme version and my car runs like a top with them. you should check the gap on those platinums because my vehicle calls for a larger gap than the platinums had. I think you should try different plugs until you find a brand that your car likes.

For some strange reason certain brand works better on particular car manufacturers. Like on Ford would use Motorcraft or Autolite, GM with AC, Old Chrysler Champion, Japanese NGK, Euro...I still put NGK...but NGK in a Ford didn't run better but cost more so sticking to Motorcraft..

I've learn to stick with what is OEM.

If you have not install them, I would return it and find the OEM spec NGK . I don't need to find out if the Autolite are good or not good in my car if I already know the NGK is good enough.

Asian vehicles only work with NGK or Denso spark plugs. Autolites when used in Mitsubishi motors have a track record of frying ignition coils! Using Platinum or Iridium will not give you better horsepower. They just cut down the replacement time intervals.
