Pulstar performance spark plugs??
Hey guys,
So I'm thinking I need to change my plugs on my 4.7 since I don't know when the last owner changed them or even touched them. It's at 75k miles but anyways I was on auto anything and found these pulstar performance series plugs, now how good are they? Do they actually give more power?
They claim to give you 12% more hp and torque which I don't know is true.
Thanks
