I've seen multiple threads about spark plug requirements for my 2006 HCH II, but some provide conflicting guidance. Could someone please tell me which Denso plug part number I should use on my 2006, along with gap and torque specs?

Thanks!

 

Really? Where is the conflicting guidance?

They come pre-gapped. No adjustment is needed.

use anti-sieze, 13 ft-lb torque.

 

I've seen different part numbers listed from various sources. Are these correct parts:

12290-RMX-004 008 SPARK PLUG (SK20HPR-L11) (DENSO)
12290-RMX-014 008 SPARK PLUG (SK20HPR-L11) (DENSO)
12290-RMX-003 008 SPARK PLUG (ILFR6J-11K) (NGK)
12290-RMX-013 008 SPARK PLUG (ILFR6J-11K) (NGK)

I'm also not clear on what the difference is between each pair listed for each manufacturer. They have the same model number, but the part number varies slightly.

 

As you notice, the manufacturer number is the same. The difference in OEM P/N isn't relevant. Likely a stocking issue or former supersedure.

Dealers will charge you $25/plug.

Just get the NGK/DENSO part number from a parts store for about $14.

 

Thanks for the advice!
