What are the best spark plugs for h22's mostly stock? Im in the market for a new set, and I want the best for the money. I'm looking towards the platium fours. I've seen what they can do to normal cars, their pretty impressive . I just didnt know if they would be a good choice.

 

I've heard NKG Iridiums are good. But i'm not changing mine.

 

I have had bad experiences using bosch anything on my hondas, but thats just my observations.

ngk's are the way to go. i have had no problems running ngk iridiums.

 

Denso, NGK.

Keep in mind the platinum/iridium thing is mainly for extended service life. That's why the service interval on newer models is 100k miles. I'm running the stock iridiums in my engine and will change them out with the same at 50k miles.

Splitfires, +4s, etc, seem to be too much of a gimmick in my opinion. Sorry if I offend anyone.

I just had some NGK platinums installed in my 98 Prelude and i noticed a good difference.
