## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    LT1 Runs Smooth as Silk.
  

*by P***C on Reviewed in the United States 🇺🇸 on May 19, 2016*

These replaced a seven year old set of their +2 platinum plugs in my LT1 Corvette.  I liked the concept of +2, but I remember wondering if it ran different...  This time around, I just went regular platinum replacements.  Theoretically they last longer than the regular plain vanilla AC-Delcos.  I saw some "don't bother with Iridiums in the LT1"  with some people saying it could be problematic for the OptiSpark.  Back in the late 90s, everyone swore by platinums, so this is what I chose.  Runs smooth as silk.

These fit perfectly in my 1998 Chevy Suburban, the price is right, and I will buy again.
