theres a coil pack for each cylinder. take off your plastic cover that is covering the valve cover. there is three plastic screws, flat head screw driver works. there will be four coil packs under that. each is held down by 2 allen bolts and the wire is clipped into it. lift up on the silver clip too release the wire then take out the 2 bolts and pull the coil pack out.
this is how it works on my car, hope this helped

Just to make it as clear as possible (and because I love using Paint...)
Edited pic from above...
Also, like I said, since you'll have the coil packs off, might as well at least check the sparkplugs with a spark plug socket and a 10 inch extention...

From what I've read here in AF, some people love their K&N, others hate it. The intake on this car is actually pretty efficient by itself, so the aftermarket intake is more of a personal taste. Now, K&N filters need to be oiled to work properly, however putting too much oil has been known to make MAF sensors go bad. Either way, if the car is breathing better through an aftermarket intake, you definately won't have more lag...
