Bosch H7DCO - But from where?

Hi everybody,

Im trying to source a set of non resistor Bosch H7DCO spark plugs.
Anybody know where i can buy these from as the dealer now only sells the resistor type.

Many thanks

I assume you mean 2.6 /103.942 engine..

Bosch replacement is HR9DC, so the NGK as stated will replace the original Bosch Non R H9DC plug.

Ok .... an EVO

I don't have a chart on it , but the BP6EFS NGK is the non resistor repalacement for the Bosch H7DC.. so , that is what guys are using unless you can find some Bosch NOS somewhere.

Sometimes NAPA still has them..but I prefer NGK since Bosch started making plugs in India..........
You may want to try the serch feature in the Performance forum..they will tell you what they like the best..or even MBDOC will know ..he raced one.

Ok
NGK /BP6EFS is the replacement for that. [ H7DCO]
..but, if you are want a higher heat with a H9DCO, you want the NGK BP5EFS.
Be aware that Bosch heat increases with the higher # , whereas NGK decreases heat as the # increases..

Your stock plug is the one I first mentioned ..BP6EFS on NGK.

Yes, If you want OEM heat range ..
if high mileage or in-town driving, you can bump it to the 5 , but that is just something that is owner preference.
