Yeah, I know, but I figured I would throw out the info as I am not sure how drastically the 3.0 differs in terms of clearance, etc. All I know is that it adds two extra cylinders and has the same frame with which to contend.....

My wife's previous car, a 2002 Legacy L, was exactly the same.
I did the plugs twice, and it was no big deal.
It was harder on the 98 Forester, with a more narrow engine bay, but I still managed to do that myself, also twice.

I tried to replace all 4 plugs one Sunday afternoon. After unhooking the entire air intake system and pulling on the boots- like the plugs were attached with expoxy, I finally gotthe right side in. I looked at the left- and gave up until I had more time. What is the secret on the drivers side? There is no room! Do I need to remove both the washer reservoir and the battery to get at the front? Then what do I do about the back? I just hope this side the wires are not "glued" on!
Any help is greatly appreciated!

If you have ramps or jack stands try accessing them from underneath.

I am not sure how that generation is arranged as compared to the prior one, but that is exactly what I did - remove the battery and reservoir.
The first time I replaced them, the boots were a royal PITA. I ended up tearing one before it finally let loose. After that, I just planned on replacing the wires along with the plugs, though they were easier to remove on subsequent tries.

Apply some di-electric grease before you reinstall them.
#11 of 11 Plugs are now in!

It took about 3 hours. I took out the battery and washer reservoir and the fron plug was right there. After much pulling and tugging- it finally popped off and I got the plug out and put the new one in. I thought the back one was going to take me all day- no room! I picked up my flat iron crow bar and carefully put the long end just behind of the boot head. With my other hand supporting the other side, I gave it the pressure and "POP" it came right off! Fitting the 3 adapters and the plug extractor into the plug hole, I was able to get the last one out. If I had discovered that trick, I would have started that on the first plug and had not nearly the aggravation. Thanks for all the recommendations and help. Until I see you again in 35000 miles....
