Don't use a traditional cheap disc gapper like I did....use wire gapper...but anyway, Was gapping to .040 and went to remove plug from gapper... the freaking iridium tip just broke right off :flame: :flame: :flame: WTF... :flame:
They seem to be real fragile...so be careful. Don't think I'm going to get another replacement. ESPECIALLY SINCE IT HAPPENED ON SECOND ONE I GAPPED TOO. just gently wiggling off gapper. :flame: oh well, 38 BUCKS down the freaking drain :flame: :flame: Not going to put in my engine now, only have two :deadcow: . Staying with NGK V-powers. :rofl:

you do have to be careful for sure. I dont think they will break from combustion, but they will break from pushing on the firing tip. The NGK's use a thicker firing tip than the Densos and the Densos have been in use in many high boost engines besides the SRT-4. I will still try them as soon as I can get my hands on them. I've used them on other vehicles in the past and never had a problem gapping them.

oops

Don't think I was using the proper gapping tool. Had a Disc kind more meant for copper plugs. Oh well, learned my lesson. Still not going to mess with iridiums. I'll probally fug up again. :deadcow:

i paid 10 for mine ngk did you buy yours at
Sparkplugs.com. 38 total shipped Should have left gap alone and just put the damm things in car. :flame: 0.047 would have worked ok I think. Close to stock gap. Really wanted to try them out, but don't want to spend another 38 bucks.

the NGK IX iridium line of plugs have a thicker center electrode than the Densos, .6mm vs .4mm, I've gapped them successfully before using the proper wire gapping tool. The disc style gapping tools are too harsh on fire wire plugs, use a wire gapping tool and you should be fine at least with the NGK's. The Densos are more fragile.

Hey I just ordered a set of these from sparkplugs.com. Any suggestions on what gap to try? I got the LZTR5AIX-13 plugs. Car is pretty much still stock.

I want those exact same ones! stg1 @ 17psi (LZTR5AIX-13 ) but sparkplugs.com wants $7 per & I am looking for somewhere cheaper.

If you are considering getting them , get them in heat range 6 as opposed to heat range 5, I think its a better way to go. LSTR6AIx-13. As for gaps, I say .035-.040 should work the best in the long run and give the plugs some longer life.
