Used them when I was turbo. U will see mpg go down a little vs using iridium

 

What number did you use? Stock is 6, I'm using 8 iridium at the moment (2 steps cooler). I can't find anything with a non-fine wire and resistor in the NGK line for 8.

I'm hesitant to use anything other than the exact part# listed in the owners manual. I used a slightly different NGK plug for my 2012 TL - it was literally off by one letter at the end, and I could notice a difference in my idle. It didn't seem to change mileage or power but the idle bugged me so I switched back to the exact ones from the manual.

The ones I purchased initially had a small extender of some sort coming off the ground electrode:



The exact ones called out in the owners manual does not:



You wouldn't think something like that would make any difference but when I swapped them out, the idle smoothed out considerably. Don't ask me why. Unless your owners manual gives the alternative plug as an option, I wouldn't go with it.

 

i was using 2 step cooler and gapped at .22.

 

the fuck he clearly stated when he was turbo. no need to be rude!!

 

bump

 

What kind of answer are you trying to get if the ones here aren't good enough?

Stop with the excessive bumps

 

Please install them on your car and tell us how you like it. I went from iridium twin tips denso (while turbo) to cooper (still turboed) and took a hit on mpg. It's like 2 bucks a plug so what do you got to lose op?
