Best Spark Plugs for our Car?

[Createdtoburn]

I have a 89 GTS, and I was curious what's the best brand/type of spark plugs to put in our car? Im about to hit 200K in like 700 miles, and I want to do a full tune up on it. Deff needs a fuel filter soon. But anyway, let me know! :-)

I personally like NGK or Denso.

Congrats on the upcoming 200k, I had that moment 2 and half years ago. Now I'm sitting on about 245k.

I use NGK copper plugs in most of my cars and have no complaints. I did recently switch to Autolite plugs for my MR2 and am hopeful they don't foul as quick as the NGKs.

Personally, I'd go with the cheapest NGK, Denso, or Autolite that you can find. I've heard that some Toyotas have problems with Bosch plugs but I can't back that up with any facts.

someone had used the two electrode bosch plugs in my celica during a tune up right before I bought the car and they were fouled out rather quickly, I know a'm already running a little rich but my standard autolites haven't fouled yet.

Alright cool, I'll throw some NGK's in there! thanks

[Createdtoburn]

Crappy, well apparently NGK doesnt make spark plugs with Copper tips. That sucks. I just got the basic Nickel Plated ones for now, still look like nice plugs. Just need something for now. Not even sure what's in there hah. Soon I'll be getting these http://www.racinglab.com/nology-hotw...oyota-005.html with their nice Silver tipped plugs.

Those (Nology Hotwires) are complete scams, don't get them. Also, don't get any gimmicky plugs. There is no reason to use them, you won't gain any horsepower or mileage.

You probably got the right NGK plugs. They're copper-cored. What is the code or part number on them?

[Createdtoburn]

Hmm, I wondered about them. The NGK plugs I got say BCPR5ES-11, 6696

[toyotaspeed90]

the 5es is correct for the bigport.... the -11 refers to them being pregapped to 44

Don't run Autolite -- they don't have the heat ranges available that NGK does for imports.... if you look up Autoline for say a 1989 4age, 1989 4agze, and 1991 4age they all use the same autolite plug but different NGK plugs... the NGK variances are heat range differences.

I run NGK Platinums since 2002... never had problems. BCPR5EGP I think it's the platinum for the bigport, and BCPR6EPS? the smallport I believe (can't remember the correct numbers), either way they come in pairs.

Check the NGK website, you put in your info and it tells you which plugs you can run on your motor... I know they have the 4AGE on there because I have used it a few times for all my cars.

[Createdtoburn]

Ah ok, yeah I looked it up. I bought the "Standard" plugs for my car. The ones I took out of my engine today were Bosch Platinum 2's. They all looked pretty evenly worn out, and nothing out of the normal. Which is good to know. Anybody ever try the Iridium IX? Guess that's NGK's best plug.

[toyotaspeed90]

No reason to run Iridiums... or even Platinums.... on these older cars.... the iridiums and platinums were used for longevity.... but these motors are pretty old and regardless of what plug is in them is probably going to foul within 50k or so..... so, why not run with the coppers at $2/piece vs $7-12/piece for iridiums?

[Donald]

Actually, I have heard people say thet although Platinums and Iridiums last longer, the standard iron tipped plugs work better. Less chance of knock or ping.
I have never proven that myself, so take that with a grain of salt.

I don't know if any of my engines are going to last 75,000 miles anyway, so I just use regular plugs (NGK or ND).

Stay away from Bosch.
