I searched a little and found different opinions but mainly on for stock. What plugs should I run for intake and exhaust possibly iridium? And did any of you notice a difference over stock? Thanks guys.

 

If you don't know... this vehicle has TWO plugs per cylinder. Different plugs will make very little difference with that kind of ignition system.

Cheers!

 

Depending on the reason behind the change of spark plugs... if you are planning to make upgrades all around it is probably a good mod to do...

Iridium is a good choice cause its decently long lasting 20-30k miles for max performance, Copper is slightly better performing, but you have to change it everytime u change oil... its not worth doing...

Platinum is popular, because it is very long lasting 80k+ miles...

For an N/A crossfire going over Denso Iridium ik16s is probably pointless...
