Mechanic preferred

I'm a chick so I didn't know what to buy and when I asked the mechanic he said to get these. They worked! He said they are a little more expensive but are a tried and true brand and can't go wrong with them and so I got these

L6 4.0 Jeep like copper plugs

I replaced champion platinum plugs with these for a considerable difference in acceleration. Shipping was fast and free.
