are iridiums overkill?

[slider85]

i'm using NGK Iridiums(BPR6EIX) in my NA, barely modded right now and last time I checked they were white. Are these plugs overkill for car? Should I use the cheaper ones? What part number? What gap?

I heard to only use regular copper plugs. Anything else will give you problems.

I know that for the turbos you are supposed to just use the basic copper ones, but I think the irridium ones may help your N/A application. They are alot more expensive though...

Why would anything other than copper plugs give the turbo DSMs problems?

 

[Defiant]

Platinum plugs were dying (mechanically fracturing) much more often than they should have in turbo motors when they first came out, to the point that Bosch advised against using them in turbo DSMs.

Iridiums are mostly just expensive.

Good old copper-heart NGKs work splendidly in DSMs (and in Nissans, for that matter).

And besides, they had her:

The price of iridiums are overkill. I had them on my N/T and they were nothing special. They fouled pretty quick actually. You're better off getting four coppers for the fraction of the price of one iridium.

Without nitrous or high horspower iridium plugs are overkill. Just get the V groove NGK's.


About 2.25 each.

Part # BKR6E-11


*Edit* This is for 420a. Sorry I didn't notice you were a first gen.

If you really want to go with iridiums, I have a set of densos, used for 100 miles. You can have them for $15 shipped. They cost $70 shipped new i believe

I just took out my iridiums and when I bought them the package said not to gap them. when I took them out they were gapped right for a turbo at about .030, but not for an NA. i put in the V-groove ones at the correct gap and the only difference so far is the engine seems smoother.
