I've done it with the headlight in place, but it is tight. 
Pull off the intake hose behind the light and pull up the 
panel that it mates to. Use a screwdriver to pop off all 
the clips holding the top of the box to the bottom--I 
think there are six of them.

Now you should be able to force the top of the box up high 
enough to get the old one out and slide the new one in. 
However, I have long and thin arms and digits, so YMMV. 
Also note that you'll be putting some serious stress on 
the big intake hose that goes from the MAF sensor to the 
throttle body, so you may end up with vacuum leaks if 
yours is marginal to begin with. Also watch for splits in 
the hoses for the ISV.

I just replaced my whole airbox with a K&N cone that I 
bought almost 2 years ago. I've had a K&N panel in the 
box for probably 3 years. The panel was a little dirty, 
but still wet with oil. I ran a clean rag along the inside 
of the top of the box to see if any schtuff was making it 
past the filter, but it came out clean. I guess the panel 
did it's job, we'll see about the cone.

I doubt the cone does anything for performance (maybe a 
little on the top end), but I don't care because the sound 
is great! At least it'll be easy to inspect and clean. I 
plan to build a heat shield soon based on Christian Long's 
original plans, and I'm thinking of using one of the OAT 
sensors for some before and after readings.
