Well I'm going to do some basic maintainance work on my civic and I want to know what you guys think. I will be replacing the spark pugs, air filter, distributor cap, possibly rotor.

Should I buy these things online or go to NAPA auto parts for them?

I want to get a K & N filter and I see them on Ebay for about $45 after shipping, seems kind of high to me?

How much would you say the other parts will run?
