    Comments about NGK Nickel Spark Plug (DCPR8E):

    Bought a used Sea Doo from dealer who was supposed to have tuned it up and changed oil. Suspect that he did neither, based on the performance on the first test ride. Spit, sputter and run about 1/2 speed. Treated the used gas. changed the oil and changed all three plugs and now runs great as it should. Dealer thru in a new battery only because his mechanics forgot to charge the old one when they loaded it on the trailer prior to my arrival. Once he had them change it, she started and idled fine. Didn't find the rough running until I took it to the lake. You can always trust NGK for a good spark.

        OEM replacement plug for my Bombardier Outlander 400 Max 2-Up. Machine became hard to start, backfired, then would not start at all. Existing plug had spark just not good color so I tried the cheapest fix first. New plug fired up first try and has started flawlessly since, occasionally in single to negative temps.

          • Q:

            There is an R in the part number that indicates "resistor" so that I understand. What is the significance of the R under the brand NGK vs a plug without the R.

              Hi Dan, I'm glad to assist you. This NGK Nickel Spark Plug (DCPR8E) (Part No. 4339) has part number with the (R) have a resistor, and the part numbers without the (R) are non-resistor spark plugs. There is no much difference between resistor/non resistor plugs. The resistor plugs will combat typical RFI.

          • Q:

            Under the Specification Tab, the Tip Configuration is described as Loose for NGK part #4339. What exactly does that mean? The reason I'm asking this is the terminal nut is not removable on the ones stocked in the stores.
