I am currently runing NGK tr6's in my truck and they havent given me any problems with 14psi...besides the sputtering problem which i think is related to the fuel pumps/fuel filter..... since im getting rid of the eaton, and adding a KB. . . will the usage of the tr6's do me well? or will adding denso's be a smarter move?? whats the best plug to run, while running a KB producing 13-14psi?? thanks

whats the diffrence between IT22's and the BR7's i noticed a $70 diffrence!

 

Denso IT22's would work well, they are a colder plug than the tr6's

 

tr6's for since 3,000 miles for me. I think im about to go back to a2lb lower and run tr5's with that setup.

 

Denso IT 22's

 

I just ordered mine from PSP, and I asked the exact same question. Sal said that the difference is in the idle quality.

so which ones did you end up getting? im starting to think that my sputtering problem (which only occurs when im at WOT above 4,000rpms) is from my tr6's....maybe the denso's will fix it! are the IT22's worth the money?

 

Leo,
On my truck the 6's run fine but the Denso 22's give me a really good idle. Enough of a difference I spend the money on the Denso's.
You need to fix the sputtering problem first.
Call me and lets talk about what it is doing.
