Anyone have a close up pic of the Iridium Spark Plugs? I have 16,000 miles on my truck and was going to upgrade to the tr6's but since these are good from no mods to heavily modded trucks i thought i would give em a try. Anyone tried them out yet? How are they? Only thing that gets me is the price and i really want to know if they are worth it.

 

Their well worth the $ in my opinion. Our price is $90.00 a set. here's a close up picture of the plugs....JL

 

GO ahead and spend the money for the Denso's.... I think you will be much happier!!!

 

They don't hold up to nitrous any better than any other plug i've tried. has anyone subjected them to high boost, like 12+??

 

All JL runs are the IT20's, i Think Totaled runs them as well.....

 

Just put the Denso Iridiums in from JL, they feel sharper and crisper. Much better on top end as well. I gapped mine at .040" and all is well. I am also using JL's chip and a 4# pulley.
