about to replace plugs. The motor is a jdm itr and it has the PFR7G-11 NGK plugs right now. Should the replace them with the sameones. How are the DENSO plugs. Your experience with either plugs would be helpful.

I'm using the NGK PFR6G-11 and they are fine. I'm not sure why the difference between the JDM and USDM plugs. NGK

 

Different heat ranges due to the higher compression of the JDM motors.

 

I, too, would suggest NGKs. Seems that I have never had a problem with NGKs in my Hondas... cars and bikes.

 

Doesnt matter. Some come factory with NGKs, some with Densos

 

I recommend what BlueR said.
