now i been hearing about people upgrading there sparks plugs to Iridium Spark Plugs..some say its not worth it cause its not a high performance engine or only good if you have a high modify engine....and also some say changing the spark plugs could throw some kind of timing off and cause the CEL....

i been thinking about getting these just to see how they perform

I look for thread on this and others and there seems to be be anything on little stuff like this..but i might give it a shot and try it

 

The spark plugs that are in the car when you first purchased it are already Iridium, which also last until 100,000 miles. There really is no point to change them unless you feel they're really fouled. If you use anything else but Iridium Spark Plugs on ignition coils, it will surely throw a CEL.

 

you can run non-iridiums on the car without a cel. Almost all of the benefit of having irdiums is that they last longer. Iridium is a very low corrosion material.

But like he said, the car already has iridiums. Denso is supposed to be what they use but I hear that some come with NGK. Both are very high quality plugs.

 

I use NGK iridium 1 step colder.
