carfreak85 Posted February 8, 2005 Share Posted February 8, 2005 NGK hands down. The FSM calls for them and subes just seem to run better on them than anything else. We changed the champions out of Wagonpowaa's brat and it ran better. Took the Boschs out of my T-wagon and it ran better. Replaced whatever was in Lepetitprince's brat and it passed emissions.

juxtaposed Posted February 8, 2005 Share Posted February 8, 2005 I use the Bosch Platinum +4's. There was a great improvement in performance, and 25k later I still have no complaints. What I don't know though is if more standard plugs would work just as well. Quote Link to comment Share on other sites More sharing options...
MorganM Posted February 8, 2005 Share Posted February 8, 2005 Your owners manual suggests the best spark plug for your car. Don't take my word for it, take Subarus Quote Link to comment Share on other sites More sharing options...
Snowman Posted February 8, 2005 Share Posted February 8, 2005 NGK all the way. That's what was used when the engineers were designing the engine. Quote Link to comment Share on other sites More sharing options...

ballitch Posted February 8, 2005 Share Posted February 8, 2005 you can run platinum but isnt that a bit hot for our engines? i agree, NGK all the way. but absolutely dont run iridium, way too hot for our motors. at least thats what im told by a suby tech in salem. ~Josh~ Quote Link to comment Share on other sites More sharing options...
Tiny Clark Posted February 9, 2005 Share Posted February 9, 2005 As long as the ceramic is the same shape, regardless of being iridium or platinum, the plugs are in the correct temp range. http://www.sarehkala.net/Spark%20Plug%20Hot%20&%20Cold.htm Iridium and platinum are used for the electrode surfaces, which have little or nothing to do with heat range.

SlipSquad Posted February 9, 2005 Share Posted February 9, 2005 NGK LASER PLATINUM BADASS! period! Did a basic tune-up on my 2.2L Legacy today and threw some NGK's Laser's in there & a new fuel filter & oil change with AMSOIL SYNTHETIC, then took it for a spin.. SHE'S AWAKE & PISSED OFF! *note* not saying the spark plugs alone woke the car up. Quote Link to comment Share on other sites More sharing options...
blitz Posted February 9, 2005 Share Posted February 9, 2005 Denso makes a good standard "U-groove" plug (comparable to the NGK V-groove), but I don't care for their iridium plug. The SOA sales brochures for '05 show iridium as standard equipment in the turbo motors, and platinum as standard in the N/A motors. Not sure if they're still using Chumpion's or not.

BigMattyD Posted February 9, 2005 Share Posted February 9, 2005 I know I am going to get blasted for this, but 40000 miles ago I put basic Autolite plugs in my 2.2, and they have performed perfectly. I inspect them about every 15000 miles, and they have not had much wear. I just replaced them with Autolite platinum with no problems. They were inexpensive at Wal-mart, and they seem to work fine. Granted, I am not racing or offroading, but I have had reliable transportation, excellent fuel economy and easy starting. Personally, I have a feeling that the spark plug debate is probably similar to the oil debate... Use whatever you're comfortable with if it works well for you.

Commuter Posted February 9, 2005 Share Posted February 9, 2005 Just to mess with everyone a bit... TorqueMaster. I've had them in my car now for ~200,000 km. Commuter Quote Link to comment Share on other sites More sharing options...

The Scooby Posted February 9, 2005 Share Posted February 9, 2005 dont waste your money on Bosch plus, the platnum 4's, any time in the normal driving rpms the spark hits the side not the end of the probe, its only upper RPM it hits the end, also the bosch's that have more then one electrice probe, or per say split fires, are a waste because they thake up the area around the electrodes, meaning that its less air/fuel mixture to be around that spark energy, meaning less spark distribution. if you want plugs that will last and be best bang for your buck, get NGK's or Denso platnum or iridum plugs for our cars. bosch plugs are made for AIR COOLED ENGINES ONLY. if you want more information on this please PM me.

Matt Actually, Autolite plugs are pretty decent. That's what we run in all of our gas-powered vehicles at work. I still like running NGK's in Japanese vehicles though.

unverviking Posted February 9, 2005 Share Posted February 9, 2005 Always replace with what the OEM put into it. Subaru uses NGK, Chrysler uses Champion, GM uses AC Delco, Ford uses Motorcraft or Autolite, VW uses Bosch (at least my Bug) Not sure about the rest, just going on what I've worked on in my time...

Setright Posted February 10, 2005 Share Posted February 10, 2005 NGK V-Groove. Tried everything else. Almost. (My EJ22 didn't mind single ground Bosch Ytrium.) Quote Link to comment Share on other sites More sharing options...
Commuter Posted February 10, 2005 Share Posted February 10, 2005 The same set? Have you regapped them? The same set. They are not "gappable". Very interesting plug. I haven't looked at their website recently (it was quite 'sparse'), but it does explain the design briefly. The main reason I decided to try them was to combat the carbon issue that the Phase I 2.5L engine has. *shrug* I may have helped a bit. Hard to know. Just tried to go the website and it seems to have disappeared... ??? Commuter Quote Link to comment Share on other sites More sharing options...

SHE'S AWAKE & PISSED OFF! *note* not saying the spark plugs alone woke the car up. I just looked up the NGK laser platinum plugs and sounds like platinum is on both center and ground electrodes. This should be good for subaru's wasted spark ignition system. Where do you get them and for how much? Quote Link to comment Share on other sites More sharing options...
JT95 Posted February 11, 2005 Share Posted February 11, 2005 When I tuned up my 2.2 after buying my wagon, the parts store I got my stuff from did not have NGK plugs. I've never used NGK plugs, so it didn't seem like a big deal to me so I got four Bosch plugs. Then, a few weeks later I read a discussion on here about how you should only run NGK and that Bosch plugs could be bad for your heads. My car seemed to run fine, so I left the Bosch plugs in. I'm getting ready to swap them out now and am going with the NGK. Curious to see if I notice any difference at all. When I had my El Camino on the road I ran Splitfire plugs and did notice a little bit of difference in better mileage. I didn't even assume they made those for a Subaru and someone told me those plugs only really make a difference in Detroit steel anyway.

THEY WORK beautifully man! Seriously! I paired them with new plug wires, they were kinda rusty. Quote Link to comment Share on other sites More sharing options...

Sorry for double posting like this.. But He's got a point.. I used to run AUTOLITES and few degrees colder in my H22 delSol w/ a 100 shot of NOS.. the only reason?? Cuz they were dirt cheap to run on the track where they got destroyed every lap!! But on the ride home.. Please believe the NGK's went back in!
