Their really great I just need 6 spark plugs and I had ordered this 4 pack first...couldn't cancel so I ordered a pack of 6 the next day and just returned this 4 pack.My crz is more responsive worth the $Re gapped to .026”. Car runs much smoother now with no misfires or stutters. Very happygood product, great fit and performance, arrived on time, even during covidonly ones I can use in my Cruze last about 40,000 milesI know that a spark plug in most cases do not increase the power of an engine... What I have learned about the small displacement ECU controlled multi valve engines is that a colder heat range with smaller electrode spark plug is going to allow the ECU to add more ignition advance and the lesser amount of electrode projection is going to allow better intake flow into the combustion chamber.... Before and after dyno runs by Oscar Jackson of Jackson Racing and KraftWerks Superchargers has proven this to be true on Honda Fits using this same IK22 Denso spark plug.Go through proper gapping procedure to get max benefitsInstalled these on my 2011 CR-Z at 95000mi (ish) and its been running fine for the last 2kmi. I'll try to remember to post what they look like after 50kmi of use.Overall, I'm glad I got these instead of the expensive OEM plugs.excelente producto
