Then I would suggest maybe something like this:

Denso Iridium Plugs for 02 - 05 WRX (1 step colder)

Under $50 for a set of quality plugs isn't bad.

Did mine a few months back...followed this very tutorial. I found it to be fairly easy, once I got a small breaker bar that would fit in to get out the back driver's side plug. You spend most of the time just moving stuff out of the way to get access.

Don't take offense..people found it humorous because you're asking for directions in a thread that has, well, the directions.

Simply go to page one of this thread..Big Sky has a great writeup.

A thanks to the OP for making this thread. I plan on using the NGK plats tomorrow. 144k on my 02WRX and a P0171 code. No record of past maintenance.

As a side note, after changing plugs xx number of times in EJ25s, I use a spark plug socket with the rubber inside, and a 5" extension. My trick is using a thin layer of electrical tape to keep the socket on the extension together when you pull it out after putting the new plug in. Just enough tape so it keeps the two pieces together and not too much that it doesn't fit in the spark plug hole. These two pieces give me just enough room to get a socket wrench in there, as well as my torque wrench for the 15ftlbs for all 4 holes.

Also another side note, when you take the bolts out for the windshield washer fluid reservoir, be sure to use anti-seize on them when you put them back in. I can't found how many of my old cars are running around with just one of those two bolts left holding the reservoir on. Same deal for the two bolts that hold the front air duct to the radiator frame.

^ good tips- thanks

Also I would never use that gapping tool one Iridium or Platinum plugs due to their thin center electrodes. You might break them as that tool applies force to the center electrode. I use one that applies force only to the side electrode.





Also make sure the harness plugs for the coil pack go back to the same location they came from!

Good tip (no pun intended).

I usually tape my harness with numbers so I can't forget what position they go to. It's easy to forget once you have them all out (don't ask me how I know...I was 16 once too).
