So my car is about to break a year and i think that it's best that i do a tune up. I've been looking at some different types of spark plugs and I just don't know which is best for my crossfire (05 Limited). On Advance auto parts they have a Denso IK16 Iridium Power Spark Plugs and dont know if they're the right ones for my car. So what spark plugs do you use. And i really dont need anything fancy, if anything, i rather have the ones that save me gas since i drive my crossfire daily. Also should i get a K&N air filter or the OEM one's? Since my car has free oil change and maintenance, everything else is getting serviced by my dealer. Except for the spark plugs or belts, etc. which we be done by myself

again thanks again!

Love my crossfire, had it for a year and boy is it a solid rock, drive it everywhere, everyday!

 

How many miles on the car? Maybe you really do not need plugs yet.
You asked the same question a while back and got an answer, do you want a different answer now?

As far as the air filters go, K&N's are popular but paper ones work, again it's up to you. I'd go with the K&N's but ....

 

I used the plugs and wireset from needswings, I also bought a k&n filter set since it'll save me money in the long run.
