Spark plugs?

[spareparts]

I've sold thousands(probably 10's of thousands) of NGK plugs over the years. I have yet to find one NGK plug that was bad out of the box. I have never seen one that was worn out. I've found them fouled by gas, oil and water, but never worn out. Years ago, I worked on cars, were stocked Champions. generally out of a box of 4, I'd find at least one that was bad. the only reason I put Champion junk back in a motor is if its called for by the OEM. Once we did a back to back dyno test on an OMC looper with a dyno. It was the k$O dyno that reads psi, not HP, we went back and forth between the same set of champions and another set of NGK's. The K&O is not the most accurate dyno, but we consistently got 20 psi increase over the champions, we went back and forth on the plugs, the NGK's consistently made more psi. Auto light makes a good plug, but they rust real quick in a marine application. AC has a plated plug thats usually the OEM plug in most GM blocks. Mercury uses NGK across the board except for a few 3.0L applications(something to do with interference with the ecm). Yamaha uses NGK exclusively. Next time you have a regular(not one of the high dollar ones, just a standard plug) Champion plug laying around, drop it on the floor, it will shatter including the core. You can do the same with a NGK, AC, or Auto light and the core will remain intact. The only application I've found that a champion does better in is in a lawn mower

Try putting anythingbut a CHAMPION in a late model CHRYSLER product and see what happens. I don't know how many trans won't shift right and check engine lights I fixed by putting a set of CHAMPIONS in when I worked at DODGE. The customer would always say I just did a tune-up and now it won't run right, put in a set of worn out CHAMPIONS to prove to them that the plugs were the problem.
