Im in the process of putting headers on my car and i was trying to decide if i was going to change the plugs out or not.........my car only has 27,000 miles on it and when i took them out they were in great shape. But since they were such a PITA to take out i thought i should go ahead and change them out to save me the troule of doing it later. The question is what plugs you guys use and what are good ones to get. Ive seen bosh iridium 4 something or others and the the quad platinum something, but i just dont know............any suggestions?

not really worth changing them, just get your car tuned after the header install. If you were upwards of 100kmiles, then i'd say otherwise.

They have to come out anyways if you are putting headers on. Personally, I think it is worth it not having as an issue for that much longer. I have seen many people who are naturally aspirated people are using NGK TR55s. You can even get the Iridium version for a longer life.

Change them. NGK TR-55's. If you plan on spraying anytime soon, then go with TR6's.

Save yourself the heartache and broken skin and change them out now, also you may end up cracking one while instailing your headers so it would be nice to have them onhand.
