I have been using NGK spark plugs for two decades and will continue to use. My Lincoln LS factory spark plug read Motorcraft on one side and NGK on the other. They were Iridium and at the time were $14 each. I coughed up the money and installed the NGK. Shortly after I did some reseach and found Champion made a double Iridium for $7 range. I installed a K&N filter after discovering the horrible fitup of the stock airbox. The lid never fit right and I was conserned about letting unfiltered air into engine. I put the Champions in at the same time and had problems Junk. Only after changing to K&N did I have check engine faults. Many and often I would take a trip to Advance to get the code. All were air/fuel related. I had a super lean condition I attribute to the Iridium plugs and filter. Plug insulator was ghost white but engine never misfired. Long story short I changed to single platinum NGK and that cooled things down just enough to correct fuel mixture problem. Single platinum cost roughly $8 less than Iridium or double platinum. My car has hit 27.5 MPG on the highway and I am very pleased with general performance. I have 116k miles on the car and have NEVER replaced a coilpack which is highly unusual. Great spark plug. I use them in my lawn mower and have never pulled more than 3 times in the spring initial start.

These plugs were recommended on various auto forums so thought I would try them out. I was disappointed when starting the car after completing the plug swap I had a misfire. Found that one of the plugs had cracked around the ceramic material. I have never broken a spark plug before so was kind of dissappinted that these were so fragile. Would not recommend.

                    Dear Customer Care, please read the question you are responding to prior to responding. Customer wants to know if Anti-Seeze should be applied.
                    My personal opinion is NO, unless you are using in an unprotected location, I feel Anti-Seeze will only add to electrical resistance.
