### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Nice plugs, do the job
  

*by A***Q on Reviewed in the United States on December 23, 2012*

I used these in my 2004 Silverado with a 4.8 a few years ago for the 100,000 mile change and they seemed better than stock and have been going strong for 90k, its about time to change them again and I will definitely use these.  I recently added a 2003 Suburban with the 6.0 and 160k that still had the factory plugs, talk about a night and day difference.  I can't say how much better they might be than stock but they work and for the price its worth it to me.
