Question NGK DCPR7EIX plug

Has anyone had real time experience with the NGK DCPR7EIX plug compared to the Bosch?
I question the single ground on the NGK as compared to the split ground on the Bosch.

Re: NGK DCPR7EIX plug

I have a set that have been in for over 30,000 miles and they have worked just fine...I will change them fairly soon though.

Re: NGK DCPR7EIX plug

Don't know about experience but I did the 12k and used the NGK and don't seem to have any issues.

I ran them in a high compression V-Twin and they were fine there also.

That iridium is tuff stuff.


I don't think plugs or fuel or air filters need changed at 12,000 based on what I saw on mine at 12000. I will do it while my warranty is intact, but after that I will run the plugs, and air filer 24,000. I will hold judgment on the fuel filter after I do my 24K. At 12k I could not get any dirt out it no mater how hard I tried.

I notice you have a newer LT, did you notice any performance difference?
BTW I did my air filter @ 12K (way to soon), fuel filter AND metal quick connects @32K. (just for preventive maintenance.) Now time to do the air @ 40K....

Re: NGK DCPR7EIX plug

Most all autos run platinum plugs for 100K , I have 30K on NGK IR plugs and see no change in then visually or performance / gas mileage . Just do not run so long as the gap opens up too much as this will run up the secondary coil voltage and this will increase the chances of coil pac failure from insulation breakdown .

I am not one who believes spark plugs give any performance gain. No matter what the hype. Even guys who Index Plugs say it is more for them, then performance.

So no, I did not notice any difference either in mileage or performance. Just the wallet

Re: NGK DCPR7EIX plug

I am running NGK DCPR7EIX on my 04 LT
and Split Fire on 03 LT.
Other than the slight sound difference they are about the same. Iridium sounds better and feels like an airplane......:-)
