Spark plug and wires

[Ferio_vti]

I, unfortunately, drive a Civic sedan. Looks nice, compared to 2001+, but moves like a slug.

Want to give it some power, without blowing the bank. In otherwords, no turbo. Yet.

So far, all I have put on is a cold intake. Maybe a new header/exhaust...

Anyhow, I was told I can change the spark plugs and plug wires. Is this worth it?

not unless you are miss firing it will do nothing for power.

You got to ask yourself how much power do you want? and what is your budget? If you want to buy a turbo some day the header is a waste of money.
