hey all

my Mazda 6 is a 2L petrol and im wanting to upgrade my spark plugs. im looking for mid to high range. i have a set of racing plugs in mind but cost to much. so was looking to see what others have been using

 

Not going to happen; if you change your plugs away from the factory spec units then, if anything, expect a drop in performance.

 

Well, you won't necessarily drop in performance, but yes, there is plenty of plug hype.

GREAT dyno results: Sparkplugs.com - Spark Plug 411

 

thanks for that.

i'll be doing them shortly. for the power incresses i'll just stick to the same type.

 

A huge selling factor of new plug materials like platinum, iridium, etc., is the extended service life, not improved performance. It helps manufacturers with their claims of "60,000 mile tune-up interval". If your plugs are easy to change, and you don't mind doing it, pick-up something reasonably priced like NGK G-Power and you'll be happy. I have been.

And I'll throw-in my standard pitch for RockAuto.com.
