I was talking to a friend about the WRX, thinking of the engine layout and I'm like... how would I change the sparkplugs. He tells me dealership would have to do that. Is this true?

It can be done, but it's a real pain. I'd just let the dealer or a Subaru mechanic do it.

No.

In fact, just yesterday someone posted a thread in the Service and Maintenance forums documenting the procedure for changing the spark plugs.

Did your friend tell you this because he thinks it's too difficult to do on your own, or because he thinks there is some rule that Subaru won't allow you to change your own spark plugs?

He just thinks it would be hard for me to do. I can see where he would think that because when I looked into the engine bay it was covered with lines, wires this and that and just crap everywhere!

BAH, it just involves taking out the Stock Airbox on the Right side, and the Battery and Water Spray tank on the Left. Then you've got pretty good access. After that....... you just need the right tools. If you don't have these, then have a mechanic do it.

If thats all you need to do then thats no problem at all. I was just getting worried because I was thinking back to this old domestic they made, I believe it was a mustang of some sort where you had to lift the engine to change spark plugs, thats how cramped that engine bay was.

Thanks guys!

Porsche 911s usually have to drop the entire driveline to change the plugs.

All flat engines go the WRX/RS/TS isn't as bad. It's definately more of a pain than a Honda Accord.

I plan to change my own plugs. The dealer doesn't HAVE to do anything. They're only human; theoretically you can do everything they can.

I would have the dealer do it just to be safe. IIRC you have to go under the car.

It's easiest when on a lift, that's why it's best to have a gas station/mechanic help you do it or have it done at a mod friendly dealer.

Or you could take too long, get more familiar with your car, clean and inspect every part as you remove it, and be a happy enthusiast.

Yeah, that's great for you guys in California.
You've got 12 mo's/year to putz around, disassembling your car like an archeological dig, polishing it with q-tips and whatever.

If my 30k service is due in February, I'll be a happy enthusiast if I can switch out the plugs before mah fangers turn blue.

Peaty's site has some good information, as always:

Here is a thread

Here is a pic

Here are some other nice pics

Bottom line: if you don't feel comfortable in the engine bay getting your handy dirty and likely drawing blood then best bet is to take it to the dealer. Plug change should only take 1/2 hour to 1 hour if you know what you're doing.

Good luck!

Took me less than 20 minutes to change the plugs in my RS the last time. Of course I don't have to unscrew anything from the top of my plugs to get them out. If the WRX is like my RS and my GL then it wouldn't be any easier to get at the plugs from below - something about fenders and front drivetrain/suspension being in the way. With a Cobb intake all I have to do is pull the wires, swap the plugs, and push the wires back on (pass side). On the driver's side I pull the washer tank out first, but leave the battery in. It's really not hard. Just remember not to tighten the plugs too much.

Ditto on the drawing blood comment. The engine bay is definately not hand friendly.

Had owned 2 different Porsche, 911's both of them
and changing plugs on them was much easier than
my WRX. Could actually get to the plugs w/o removing
any other parts.

But WRX, airbox, passenger side and water bottle & battery
on driver side. Taking my time 1.5 hours, thats about 2 beers.
and a 2 cigs..and a few dumb looks..

I believe it was the big block Corvettes in the late 60's and early 70's that required loosening the motor mounts and jacking up the engine to get to the plugs. Some owners just drilled large diameter access holes through the fenderwells.
