any opinions? They seem to be the thing for the Lightning. They claim there pretty good

 

Do they even make a plug for our trucks ?
I been hearing some negative things about the quality of the NGK plugs maybe just a bad batch made it out to the market?

 

i dont know. i would think they would. maybe not.

 

http://www.densoiridium.com/ and you can look up the part number for your application. For my 99 5.3 it's IT16 gapped at .050 and I've thought very hard about buying some but I want to know for sure if that u-groove in the ground electrode really helps.

 

They look cool but $11.99 per plug seems a bit steep. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

 

I have a set of IT24s waiting to be installed but I keep putting off the 4 and 1/2 hour job. I need the colder 24s because of the 5lb pulley. I'm running NGK BR7EFs right now--they took me the 4 1nd 1/2 hours to change.

They are expensive but they do not misfire. Probably not necessary uless you're running a s/c/turbo with high boost levels. My OEM plugs were fine with a 3lb pulley and got me into the high 12s.

i can change the plugs in my blown chevy in less than 30minutes, 15 if it is cool.

 

explain why it takes 4.5hrs. i could chang the plugs in my turck in 25-30min. no prob.

 

Because he drives a lightning. I read in a magazine it is easier if you pull off the wheels and remove the fenderwells.
