Ok Complete Noob Question

[Brick]

about to order some plugs.. are all LFR6AIX-11 the same? about to order some from EBAY and there are so many listings. Some say for their cars but don't list nissan at all. Is there different variations of this plug? or is it just to confuse people like me that they list it like that.

[bigkevracer]

Should all be the same. Some listings just mention certain cars so they'll come up in search results.

Here's an old link I found on here, still works: http://www.ebay.com.au/itm/160704553314?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

I've got the Densos and no complaints so far, but apparently Scott found they don't last as long.

I was pushing them quite hard Ryan.

I run the LFR7-AIX plugs now with no issues. They are the same as WRX etc, they will fit fine Josh.

That's a good price on the listing you linked Ryan. Are they the right heat range though?

The ones I bought said 1 step colder than standard for FI applications.

I don't know where 'Heat Range 6' fits in the greater scheme of things.

Oh, & I was going to post a pic of one of my plugs. It was obviously the cause of the non firing cylinder I had a month ago (the electrode was missing).
