performancewise>>what are the best spark plugs for the Sedan?
Where can i get them from???

 

The stock plugs you allready have in the car.

 

Depends on what you are doing with your car. For N/A and an everyday driver the stock OEM plugs are already pretty damn good. I think they cost around $14 a piece. They are the NGK PLFR5A-11 Laser Platinum Plugs. The platinums will last a long time and offer consistent spark performance. For more demanding environments such as FI, heavy track use, etc. you can go to the more expensive iridium plugs. Even if you don't have FI or race alot, you could use iridium plugs, although it would be unnecessary.
