Careful with a gapping tool. Iridium plugs & many types of platinum plugs have a very tiny bit of iridium or platinum in the gap. That tiny piece of metal is pretty easy to break off.

 

I hope they're pre-gapped! I just puta new setin my car a week ago thinking they needed to be replaced, but I found out there were already NGK iridiums in there haha. My buddy had threw them in there a few months prior when he was doign work on my car and I didn't realize it. Almost a waste of money, but oh well.

 

They come pre-gapped. When I changed the plugs in my V6, I checked the gaps (all checked out fine.) I didn't bother checking the gaps when I changed the plugs on the LX with NGK double plats (I couldn't find the little gap tool I have.)
yeah i am sure the rear tree are hard to get to in the 3.0 V6. One was kind of a pain in my little 2.7 V6, but i was able to get it. It shouldn't hurt driving it with 5 new and one old for a short time.

 

i have a question...what do you think is the best plugs for my 94 accord I4 vtec(F22B1) ??im looking at the NGK Iridium IX

" NGK Spark Plug: Plug No. ZFR5FIX-11 Iridium IX Spark Plug: Sohc; Vtec; Gap @ .044 "

am i on the right track??

and what should the gap be??is it still .044"?

 

Any NGK ZFR5's will work, I have G-Power plats in mine, gaps is still .044 inches or 1.1mm
