Don't let them sell you Bosch plugs at autozone. If they don't have NGK, get comparable Denso's. if they don't have Denso's get anything except Bosch.
I agree you should change the valve cover gasket seal and the spark plug tube seals. This is easy to DIY. There are instructions with pics in the DIY section (1st post authored by sir_nasty)

 

ya. bosch + honda = kaboom.

 

I figured it out why my car is shifting weird. My throttle cable broke and my my tran fluid was ugly dirty! Just incase heres the part I'm talking about. This is a picture I just got off the internet. It isn't mine.

I don't get why I am still able to move forward with that broken cable, anyone care to explain?

Also is it easy to install myself?
