who makes the br7's and who makes the IT20's. also can u give me a stocking # off them too .need new plugs before i up the boost with my 5lb lower pulley thanx later.

 

IT20 is the Denso Iridium I belive stock number is 5326.
NGK is the BR7EF 3346 is the number

 

which ones should i use for a daily driver

 

I was told by NGK the design of the BR7EF may foul under normal driving, the Iridium is what I am getting, of course you will pay for them , depends on what you want to spend. NGK are 1.59 each and the Denso's are anywhere from 68.00-95.00 a set

 

GO with the Denso's if you drive your truck daily....

 

i aint cheap and i want to do this right the first time and not have any problems with my truck so i guess i will be call JL and ordering some denso's thanx everyone later
