Click on the bottom sticky in this forum and then click spark plug facts.

I just looked and there are no real details how to do the job.

doing the plugs on a Subaru engine isn't that big a deal - remove the coil packs, then remove and replace the plugs like you would on any other engine - the main difference is that they are on the side of the engine, rather than the top. If anything is in your way, just remove it (not sure about an 06, but on my 02, it helped to remove the battery and windshield washer bottle)

Its not that bad, took me like 1.5 hrs the first time, then maybe 50 min the second time. 1 of them had a cracked insulator, so its totally worth it

Took me about a 1.5 hrs also just did mine this wkend. On driverside i just removed the windshield washer bottle n that was it. If u have a socket driver that has a swizel head that helps out a lot. Too bad I didnt.

What plugs are you all recommending (if anything other than factory)? Car is my wife's. 100% stock.

You'll need to remove the airbox and the air pump, just a heads up.

Its only on 06+ wrx and 07+ sti.

It injects fresh air into the heads during cold start for emmission purposes.

I would just stick with the factory plugs. They work great for a stock car plus they are platinum so no real need to upgrade.

I changed my spark plugs on my '06 WRX TR this past weekend. It wasn't that bad, other than the fact I couldn't get to the one (last one) by the air pump on the driver's side (3 newly installed, 1 old one left). I noticed after removing them, they had normal wear (not sure if there's any repercussions when driving with 3 new plugs and 1 old one). I couldn't reach my man hands far enough to pull the last socket out (still managed to fit a small ratchet to loosen the bolt). I'm definitely going to try and figure out how to remove the air pump to get to the last one sometime this week.

I followed the directions on scoobymods (thanks Peaty) as well as getting additional information with the "difference" between the 02-05 models compared to the 06-07's, which isn't much other than the air pump and removals that aren't necessary. Here's what I did:

Passenger side:
1. Disconnected negative battery terminal
2. Removed front air duct (flat funnel-shaped held on by 2 bolts; connected to the snorkus)
3. Unplugged MAF sensor (carefully) then unclip hoses on top of the air box and MAF sensor wire from the side clip.
4. Removed the airbox (held on by two bolts) and air intake duct.
5. Removed the plugs held on by one bolt each
6. Stuck in a socket extension for spark splugs and loosened/removed. 7. Replaced with new spark plugs (IMPORTANT: 15-18lb (torque wrench))
8. Put it back to together.

Driver side:
1. Removed battery
2. Took the windshield washer bottle plastic screw off (to allow flexibility when working)
3. You'll see the plugs on the side.

Sorry, but unless you have barbie hands, I can't see a way to get that last plug out (nearest to the firewall) without removing that air pump. Any help? suggestions?
