Just want to verify that the part number from my Helms manual was right. NGK PFR6G-13. I just check the price online and they were $16 each! Please tell me they can be had for cheaper.

 

NGK PFR6G-11

I got mine here:

Thanks man. Did NGK just change the part number, because thats what it was listed at in my 1998 Integra Service Manual. Just curious.

 

The last 2 digits stand for the spark plug gap.

13 would stand for 1.3 mm
11 would stand for 1.1 mm

Unless you drive a GSR, stick with 1.1 mm gap. I think you may have read the GSR spark plug part number instead of the ITR one.

You can probably run 1.3 mm gap on your ITR but I wouldn't push it. I would hate to think I damaged the pistons cause of spark plug clearance issues

Thanks man, the manual had them listed as the same plug. But I'll go with the 11 as you mentioned. Thanks again.

 

or you can just get the 13s and regap them

 

that's just way to much work

 

Good point, I guess whichever are cheaper, if their's a difference.
