I have a 03 acura rsx type s. i need to change the spark plugs, however there are so many choices out there. Such as NGK Iridium or Ngk platium. Then there Denso. All of theses are quite costly so i want to get some feedback before i make my choice.

what ever you do, do not get autolite or champion, total garbage. you should get double platinum tipped plugs. Platinum stays clean and doesn't corrode, the reason double platinum is because one sided platinum tipped is a bit pointless because you will not get the benefits of platinum if the non platinum coated electrode is corroded. The only iridiums I recommend are the ones that are coated on both electrodes. Those are very expensive, getting single coated iridium plugs are pointless and a money waster. But Iridium is better than platinum. Denso and NGK are fantastic brands, theres a reason they come standard equipment on cars like Ferrari and the Nissan GTR

The reason Iridium plugs are so expensive is because the material is NOT manufactured on earth. It comes from meteorites and asteroids. If you have no performance upgrades, or just bolt ons, then the factory plugs will be just fine. A common misconception is just because you have high output plugs is you are going to generate more spark, which is FALSE unless you have some sort of high output ignition to fire the spark to them.

wow that was stupid.

It is true Iridium is found in most asteroids. However, the only difference in this metal and others is that it is one of the rarest in earths crust. You do not "manufacture" platinum or gold either...or any other element. They are what they are. There would be no such thing as as a precious metal if we could manufacture elements from scrap.

Not to insult, I'm sure you're probably well versed in cars. Just want to make sure you're not repeating misconceptions about the elements.

Need to put in the ngk iridium, acura likes what it came with. doesn't like other types of splugs.
