Default Changed sparks plugs today at 57,112 miles.

Holy moley! And to think this whole time my car was never quite at its full potential. For anybody who hasn't changed their plugs and they're over 50,000 miles....please do it immediately. I am amazed at how SMOOTH the car pulls throughout the mid-range and top end. It seemed like at the very end of 3rd gear the car just kind of fell on its face and quit producing power. Now it pulls nice and tight and crisp all the way to the end of the tach.....even seems like the engine has a different sound to it too; a little smoother of an idle as well.

Anyway, +1 for the NGK coppers.

Yeah, makes a huge difference doesn't it? Is there a big difference between the stockers and the NGK coppers?

Changed mine at 52K the other week and it made a difference. Those suckers aren't cheap for the NGK Laser Platinum PFR6G OEM plug. Coppers were $2 a plug, while the other ones were a lot more!

I bought the coppers, but replaced them for what came with the car because I don't want to replace them for a long time.

Cheers

Interesting. I'm glad I used the stockers then It was kind of a pain to do, every year is a little to much.

if the thought of changing plugs once a year is an issue to you

you should not be driving or own any sort of performance vehicle because god only knows what else you might have issues with doing such simple tasks

Dooooood, take it easy. Plugs are a PITA, not hard, but not fun.

I'm wierd, lol
I actually like changing the plugs on my car
Makes it easier since the Air pump is removed and I have a cai/sri

I got use to changing them because I kept getting misfire codes and went back and forth with gapping them, changing coil packs, switching the plugs to diff cyl, and then finding out plugs were bad LOL

Dude...it was fun as heck. I loved it. Plus....what's better than getting to know your own car?

So the platinums are stock? Well then, if you DON'T have a problem with changing your spark plugs frequently, GO WITH THE COPPERS! These things are amazing.

It almost feels like I got dyno-tuned because the whole upper powerband is smooth as glass and NEVER loses power the whole way through. AMAZING!

Whoever wanted a write up...it's simple (just make sure you have 3-4 extension pieces and a swivel socket).

The bolts on the coil packs are 12mm bolts. Hook up 3 or 4 extension pieces, then the swivel socket, then of course your 12mm socket. Once you get the coil pack off, switch the 12mm socket with your 5/8" spark plug socket and get the plug out. Make sure you gap to .030, that's what I did. On the passenger side, remove your intake and air box completely (that's the easy side).

On the driver side, remove the battery and windshield fluid resevoir....that's it!

Changing your spark plugs should be the LEAST of your concerns. Call me crazy...but I'm always TRYING to find reasons to pop the hood of my car and go to work. Since the beginning of this year I've went ahead and changed....

Oil and filter (Valvoline Synthetic and Mobil1 filter)
Transmission fluid (Uncle Scotty's cocktail)
Differential fluid (Redline gear oil)
Coolant (Prestone)
Fuel filter
Spark plugs (NGK coppers)

Let's just say it feels like a WHOLE new car.

It always amazes me how something so vital to the efficient running of the engine seems to be forgotten or neglected by so many. I'd go further than the guys who suggest a yearly change and recommend taking them out every couple of months just for a look-see, with possibly a clean and re-gap if needed... they speak volumes about how your engine is running

Changing the plugs on these cars is not like a honda 4 cylinder. I would much rather pay a little extra for NGK Iridiums and change the plugs every 50k which for me is about 3yrs. So over the 3yrs coppers will cost about $10 X 3yrs or $40 for Iridiums ( $7.XX each plus shipping). I will gladly pay an extra $10 over the 3yrs to only change my plugs once instead of 3 times in a WRX. Of course if your highly modified you may want to change your plugs yearly, but for a stock WRX or lightly modded I don't think it's worth the trouble.

....I replaced mine @ the recommended 60k. I was so impressed with the condition that they were in that I swapped them with same type. The engine ran as smooth with the new plugs as it did with the originals.

and not to mention, changing plugs is a somewhat risky deal. There have been many people who learn the hard way that one screwup while changing a plug means you now get to pull the heads off (or pay someone to do it) Overtorque them, cross thread, or change while the engine is warm can all be very bad!

it is VERY easy to fit all necessary tools to do 90% of any and all 'shadetree' work
including sparkplugs
in a box that you can easily carry and store in a closet

these cars are very simple and require very few tools overall to wrench on


moaning about replacing sparkplugs once a year is lame
