When I was at the auto parts store today I noticed there was a sale on (both Platinum and Copper Classic) SplitFire Spark Plugs. It was a great price so I figured I might as well put in a new set. I told the salesman what I needed. When I did, another guy behind the counter overheard me tell him "'95 Celica" and kinda mumbled a warning "I wouldn't do it". I wasn't sure he was talking to me. I looked over, he stopped what he was doing and repeated "I wouldn't do it". I asked what he meant and got "I wouldn't put those plugs in a Celica. NGK." Someone else there agreed; NGK only.

I've see some others here use NGK, there's been talk about E3 Diamond Fires, etc. Sure, there are differences but I didn't think there was that much of a difference between one brand and another. Besides, I'd heard SplitFire's were supposed to be good plugs?

Anyone else here ever hear this (NGK only)?
Why would NGKs be so much better or more appropriate for use in a Celica?

Is this Toyota's recommendation or just opinion?

denso or NGK plugs only.

end of discussion.

Spitfire? You went to Autozone huh? 39 cents a piece? LOL I just went there today and saw that. I'm runnin NGK irridiums, I think I paid 6.99 a piece.

Toyota's tend to like factory parts. NGK and Denso make factory parts, people have found their Toyota runs better with NGK or Denso plugs/wires.

I used to have the NGK Iridium's that are $7/ea. Now I have the NGK V-Power since they are gap-able (the iridium's are not). I'm not really sure if there is a difference in power or how it runs since a lot more things have changed between using the two but iridiums are supposed to last 120k miles.

I had NGK-R and im currently using Trust GReddy racing plugs. Cant say you'd notcie much of a difference betwen the two but they were due a change.

Changed from OEM Denso PK20's (Toyota's choice of Platinum Plug) to NGK Iridium, Immediately noticed the car wouldn't hesitate as much when punching the gas, especially in neutral, and the car starts on 1 or 2 fewer clicks. 2nd gear rev matching can be done faster and closer to the target rpm now, The old denso plugs did look cruddy though, surprising for platinum. I've sworn by Iridium since the day I learnt about them and have installed the cross referenced IX plug in every vehicle I've ever owned.

not gap-able? can you explain some more?

I know iridium have that special design tip that is extra small, but i figured you can gap them with a ramped gaping tool. Can't you gap them with another tool that wont damage the electriod.

the center electrode tip is very fragile and easy to crush, if you can open the gap by not touching it I guess you could gap them. But if you accidentally put pressure on the thin center electrode and mess it up, that's a $7 spark plug you just made into garbage.

They're gappable if you know what you're doing, have the right tools and steady hands. They're not gappable for most people.

ngk coppers. bkre7 or something like that.
