Very competitive price offered by Advance for a great sparkplug.

Never had any plug-related issues.

      My bike is an OLD (1993) Suzuki Intruder 1400. That's a pair of very large jugs and stock plugs just don't cut it. These plugs smoothed everything out nicely.

        These are a great replacement for my stock motorcycles plugs. Burn hotter and last longer. And Advance is the only place nearby that sells them

            Comments about NGK Iridium IX Spark Plug (DPR8EIX-9):

            Recently purchased a '99 Yamaha Venture, so wanted to make sure maintenance was up to date. Thought I'd try these plugs, since I had seen such rave reviews about them. Upon pulling the old plugs, realized they were in fine shape - probably not a ton of miles on them. Wanted to take a look at all four anyway, went ahead and installed the new ones. Haven't noticed any difference in performance, but keep in mind the others were in great shape (not iridiums). Haven't checked mileage yet, but don't plan on spending the extra to get iridiums next time. Nothing bad necessarily about them, just don't think the extra money gets you anything.

                Comments about NGK Iridium IX Spark Plug (DPR8EIX-9):

                These plugs were installed on my Suzuki GS and fire up quickly when cold and allow me to get off the cold enrichment much quicker than with stock plugs. The engine feels more responsive at lower revs as well. The spark tip is supposedly much more resistant to wearing away and increasing the gap, so longevity makes the extra cost worth the price. Bike engines tend to wear plugs rapidly, and this should lessen maintenance time and allow me more time on the road.

                  I installed the plugs in a 2011 Triumph speedmaster.
                  So far the engine runs smooth and the idle speed has not increased (it was fine as is) as others have reported. I have run NGK iridium plugs in my Honda car, and have received long life and good performance from them. I expect the same for my motorcycle.
