Which Spark Plug to buy???

2006 SRT8 Charger
Just about to order spark plugs but need your guys expert opinion.
What do you think about NGK Iridium IX LZTR5AIX-13?
Set of 16 for 136.00 shipped?
Thanks

 

Good plug for long life...one less thing to worry about for a while.

 

try rockauto.com alot cheaper ngk 2314 stock srt8 heat range for (16) 28.00$

 

If you are stock just get stock....don't waste the money on Irridiums.

 

This place has some good info.

Those are supposedly the premium NGK's... but I noticed they don't have the NGK "R" rating. I'd be leary about trying these myself. If you get them maybe you could do a little before and after KR logging to see how much that R rating matters.

Ultimately I agree with the others and go with the OEM plugs.

Damn! I didn't believe you and had to look for myself. Incredible price.

Rockauto has the Iridiums cheaper than the stockers. $28 vs $40 for 16.

Great site but... why do they list Pulstar's as "ultimate" class... and everything else below this?

 

I'd stick with oem
