Do Performance Spark Plugs Make a Difference?
 

Hi everyone,

I've been slowly upgrading my daily car and was looking into high-performance spark plugs. I've seen some brands claiming improved combustion and fuel efficiency, but I'm not sure how much it actually shows in a practical setup.

Does anyone here use high-performance spark plugs in a street car? I'm wondering if it's worth the upgrade or if it's better to stick with the stock plugs. I welcome any suggestions!
