i just got back from kragen auto part with a 10 pack of spark plugs but i think i got the wrong plugs the plugs i took out of the ds are dr8ea the ones i got from kragen are d8ea they look exactly the same but the plugs are missing a letter can i run these or should i return them.

 

nah it will work fine but the only difference is the dr8ea has a resistor type plug.

 

someone told me the r was for race lol.

 

The question what do you need 10 spark plugs for ? It a DS ! My plugs last well over a year and usually don't need to be changed when i do change them.

 

Well, the only difference you may notice is the radio may get a little more static. [img]i/expressions/face-icon-small-wink.gif[/img]

 

i returned them and orderd the dr8ea from from ebay got a pretty good deal 12.50 for 10 plus shipping the reason i need 10 i want to perfect the jetting so in case i foul some plugs i dont want to be running to the store and i like having extra parts around lol.

 

I thought the resistor didnt allow the plug to spark till the current reached a certain amount

 

I thought they starting making them to reduce RFI (radio frequency interference).

In the old days you could get interference on the car radios, and it made a big difference switching to a resistor plug. It now also helps reduce the RFI that would interfere with on board computers, and tv's.

 

The coil generates a certain amount of energy. This energy wants to go somewhere. At a certain voltage the plug fires (regardless of resistance). Until that happens NO CURRENT FLOWS. Whether you have resistance or not does not matter. A paltry 5KOhms does not do anything when compared to the nearly infinite resistance of the gap itself (until the plug fires that is).Once the plug fires the resistance comes into play. The coil cannot get rid of its energy in the shortest possible time due to the resistance.This reduces current flow in the spark and it takes quite a bit longer until the energy in the coil has expelled itself through the resistor. This results in a longer spark. However the spark is slightly weaker due to energy loss in the resistor.

 

When My Ds650 was delivered to the house, they said not to ride next to the house, because it messes up the TV and Radio...
