    Update: HUGE  price increase
  

*by R***R on Reviewed in the United States on November 10, 2015*

Update Good plugs but price is now 3 times what I paid for the first two sets and I can't see that the plugs improved any. Yes, USA money is worth less this year but, at over $21 per plug I'm not buying these anymore. Old review still stands Really amazing plug! I avoid "hyped up products" but these really are better then any other plugs I have used in my 1999 Camry 4 cly. I am going to try them in my other cars as well. I noticed the engine running smoother right away and once the onboard computer adjusted to them I logged better MPG as well. Up 1-2 MPG Also about .08 seconds faster 0 to 60!
