The Motorcraft Iridium SP-534 Spark plugs which also has an alternate part # CYFS-12Y-T3 and LTR6CI-8 Clearly labeled on the spark plug itself is rebranded and made by NGK, http://www.partcat.com/ngk  On the NGK site and many other sites you will see NGK Iridium Spark plugs part#LTR6CI-8 AND 97177 Which is the same plug as the Motorcraft and cannot warrant paying triple the price because of a NGK Logo on the plug itself,pics below of the MC SP-534 PLUGS which Rock auto clearly has the best price of 3.95.  Z   BTW There are no images on the NGK SITE hmmm,BTW was able to obtain a Motorcraft SP-534 from the dealer and is the same exact plug.

Yes Z is correct. The SP 534 is the exact plug that NGK calls LTR6CI-11 stock #97177. It is NGK's best plug. It's double precious metal meaning it has iridium on the electrode and the ground strap. Which gives it the 100k service life compared to the single precious metal plugs such as the Iridium IX which is also a really good plug which NGK said is good for 40-50k.

I called NGK recently because I was contemplating changing my plugs. But there is a problem for me.

The stock replacement LTR6CI-11 is gapped by NGK at .032" and is stock heat range. They don't offer 1 or 2 step colder in the laser oem double iridium plug. The 6 designates the heat#, 7 would be 1 colder. the 11 is the gap designation.

If you want 1 step colder you downgrade to the LTR7IX-11 stock 6510. The problem is that plug is gapped by NGK at .044" and NGK told me they recommend only gapping down a maximum of .012" or you risk weakening the weld of the ground strap. Then maybe it breaks off in the cylinder. So that means that they only recommend gapping that plug down to .032"

So anyone running the LTR7IX-11 which is a recommended part for popular 3 bar tunes and gapped at .028"-.030" are running a little less than NGK recommends for that plug.

So if you want to gap down that far I'd run the stock plug but then it's not colder. Or you run the iridium IX line gapped down to a minimum of .032" and you can be colder but also have an inferior plug. But be careful when gapping down you don't go too far and have to go back up...You still over extended it in that case.
