Revieing an Old Thread ~ Here's Spark Plugs - Not Running NGK's R Plugs .
Running these :
NGK - DILKAR8P8SY Medium Heat Range , Believe these are Iridium - which is very good material for Spark Plugs
Most Turbo's run some sort of this Type .. I do Remember Thou when all they had were the Platinum's which had to be Changed every 20K . .
On Turbo Motors ~
Heat Range 8
26.5 mm Reach
14mm Hex
12mm Thread x 1.25 mm per Thread
Dual Fine Wire Tip. . 006 Laser welded Iridium center electrode tip
Prep Gap .043
I was just Searching around Notice a Spark Plug Update listed for this by
NGK Plug DILKAR7G11GS - WHICH Simple looks like a Marketing (( Price Increase )) as Spec's Same - except Heat Range is 7
Spec's Honda Plug seem to be Heat Range 8 . . from everything I looked @ Yet all Info out in Internet world has some Conflicts ( Best to Call NGK )
Speak with Tech Support as all Parts Places have No Freaking Idea what They are Selling . .
What I do like are for Tuned Motors with Mods - would be NGK - LKAR8BHX which Fit another Motor , but have Same Spec's Except for
Gap .032
Electrode Design : PSPE - see Picture , but Claim to be Faster . . do to
Exposed - Open Electrode Tip
Materials :
KGK # LKAR8BHX - Ruthenium HX
Heat Range 7
