Hello, i have recently bought a 2002 black honda civic 1.6 vtec, i sent it to the mechanic and changed distribution kit, i wanted also, to change the air filter and the spark plugs, but i am not sure which brands i should go for, and also, the clutch pedal makes a little noise when pressed, either with the car engine turned on or off, i think its no a big deal just a bit of oil and hopefully it will go away but i saw some scary stuff about that noise. Back to the spark plugs and air filter, i was looking at this:
Air filter:

OR

this one above is for the ep2, but i think it also works.
spark plugs i am clueless.


Also, i was searching and i found about a aftermarket intake, i was wondering what it will change, the performance, MPG, the feel, etc, is it easy to install? is it worth it? does it damages the engine somehow, all the things.
Thank you for your time!
