I am trying to locate the NGK Iridium plug's #. Can't find it in the NGK official site. Please help?

 

These plugs come in two heat ratings. BKR5eix-11 is the equivalent of a Denso IK16. BKR6eix-11, which runs colder, is the equivalent of a Denso IK20. (Denso's site has a cross-reference chart; check it out before you buy.)

The IK20/BKR6eix-11's are great for the TL-S or heavily modded TL's; otherwise stick with the BKR5eix-11's/IK16's

 

Thank you Thank you.

 

Hyde is correct unless you live in the hotter climates.......use the colder plugs then, it helps against detonation....
