Does anybody know the part# for the OEM Denso Plugs. Dealer wants 24.00 a piece.

 

what's your source? When I pulled my plugs out they were denso and the last time I checked NGK doesn't make any plugs for the IS350

fyi...the part number on your stock plug is probably a special part number for Lexus. If you go to a part store the plug will be a different number. (source: Denso technical support)

 

is there a DIY for this yet?

 

+1, also interested in dIY..

 

haha you have to check this out ! i recommand BOSCH

get Platinum Ir Fusion

if i remembered this correctly this spark plug can last more than 100,000 miles

 

OEM uses Denso and NGK. I only use OEM and I found NGKs hold up better/longer then Denso.

Of course they don't actually make plugs for this car...

Only items Bosch has for the 2IS are cabin filters and wiper blades.


IIRC the 2IS requires long-reach plugs too
