Here we go again, WHAT SPARK PLUGS

I've never been "impressed" by a sparkum plug. plugs don't make power. engines do. all a plug...any plug can do is spark when the current comes down the wire. i always just get whatever's on sale at wal mart. I've run on the street that way, raced at the track that way. I've run some high nines with wal mart champion plugs that were on clearance for 89 cents each. the only thing fancy plugs like platnium or irridium and the like can do is maybe last a little longer. that's ALL. these companies spend BILLIONS.....lemmie say that again......BILLIONS on marketing and hype to make you think that you cannot live without their "superior" plug and that it will out perform all the others. I've been wrenchin on cars professionally since 1974. the only ONE thing I have seen, witnessed and DONE myself that adds power concerning spark plugs is indexing them. and that is minimal.....but there IS gain to be had there. when you're talking about .100 of a second in a drag race that can be the difference between a win or a loss. you'll have people on here sayin how they feel more power with this plug and that......but honestly, you think anybody wants to say their stuff is "normal" and just like everybody elses junk? fact is a plug is a plug is a plug. always has been always will be. all the rest is just a bunch of frikkin BS. i say run the Champions. why? they were good enough for the factory to put um in 340s 440s and Hemis. that's good enough for me. they are also cheap and readily available. somebody says champions dont run good is full of a load. they had somethin else wrong that they'll never admit to. it wasn't the plugs fault.
