Exclamation Get those Champion plugs OUT!!!!!

I had no idea that changing my spark plugs would make that much difference. I have always known that Champion spark plugs were for lawn mowers only, but I didn't know how right I was! I put a new set of NGK spark plugs in my 2000 RS and it made a noticable difference in throttle response, idle quality, and power! Do it and you will agree!

I agree....as of yesterday I had 27k on the origional Champions....ugh...
I put in Bosch Platinums (not +4s) and it's UNreal. Torque is way up (or back up) and it runs much smoother...

Should I pull my Autolite Platinums (came used with the car) and go back to NGK copper?

Exactly...at least now they'll last alot longer than the Champion Coppers...
Still can't believe they did that to us...hell I though I had platinums like the '98s and '99s...

The Champions looked fairly good although having 27k.
I stuck the Bosch Platinums in for $1.99 a plug...not bad...
When I get plug wires I'll probably put in Denzo Iridiums.

How much trouble is it to change the plugs on this car? Are they easy to get to?
The last time I did my own plugs was on a 400CID Pontiac engine and everything was right there in front of you. The only mistake I made was to waste money on 8 Splitfires...ugh waste of $40, that was like 10 years ago.

Also, is there a compelling reason for me to spend good money on expensive plugs rather than NGK's or Bosch Platinum's for like $2 each?

I's easy to change plugs....
Ya gotta take the intake silencer tubing off (you should do that anyway for performance reasons) and also take off the wiper fluid tank (two screws) and that'll get you in there fine. 6" extension on your plug socket and your on your way.
Hope this helps...

Every car runs best with NGK plugs except for Toyota's, they need Nippondenso plugs.

You'll really be happiest with the NGK platinums from the dealer. I've said it at least a dozen times, and I still believe it. There's also something about not having to change your plugs for a year at a time...

I put in the Bosch Platinum (not+4) as well. They feel pretty nice. They were a small improvement, since my plugs only had 7k miles on them. A lot of the diffrence you felt probibaly is from getting NEW plugs in your car.

I'm a firm believer in NGKs, however when I swapped my Champions for NGKs, I noticed no difference. I didn't expect one either, however, others here seem to post noticable gains. If you're coming from 27,000 Champion plugs, yes, but then you would have noticed it with new Champions as well.

Cool

Hmm, so changing plugs at 30k should be noticable? I just checked mine and they are nicely lightbrown-grayish, perfect. The gap looked a little bit too large.
But at 1.5 per plug it should be worth trying...

WRC...Yeah...if you've got a 2000 or 2001 they put the Champion copper plugs in there...last about 15k...'98 - '99s have NGK Platinums which last quite a bit longer. Either way you should change'em. I would have sooner if I had remembered...

Actually, my 1999 2.5RS came with Champion platinum plugs. Not NGKs. I had to buy the NGK platinums separately - not all 99's got NGK's...

Part number on the NGK platinums (that I use anyways) is PFR-5B11.

I maybe off topic, but oh well here it goes:

Anyone know if we're suppose to go with a hotter or colder plug when we turn up the boost on wrx? Whats the difference between a regular plug and the hotter/colder ones?

Thanks

Went to the dealer to check out the NGKs from them was told that the plugs they had were from Subaru. I asked who made them and he did not know, Man aren't the people supose to know these things. He also told me that no Subaru comes with Champion plugs from the factory, well atleast until the book told him different, OOPS. Well needless to say i bought a set Of NGKS from the Auto store instead. Today i lost a little respect for the Scooby Dealer
I have to go there tomorrow to get the oil changed, at least the Techs know what they are doing to my baby.
Peace

FWIW, the Indy car engine I inspected used Champion plugs. Granted, they have a MUCH better ignition than a stock RS, but still, don't discount the plugs too much
