NGKDCPR7EIX Spark Plug (2 Pack)

Fire right up sounds crisp clean runs great

Instaladas en una iron 2020 y funcionando sin problemas.

These I have run in several of my Harleys. They’ve given great performance for a few years and never failed. Removed inspected and replaced. They didn’t appear to need replacing but I did anyway. I will continue running these and recommend you give them a try.

I swapped my my old plugs with these and these on my Softail. Also added thicker ignition wires at the same time and didn't notice an increase in performance.

Update: Issue was fuel related. If you get similar symptoms mentioned below maybe rebuilt your fuel pump! There's an o ring under the fuel filter that probably leaks fuel pressure. Still keeping the stock plugs in for the simple reason the engine ran smoother than these iridiums with the same fuel pressure.Original review: I have a 2011 sportster 883n stage 1 and tune. These iridium plugs create spark but are not correct for the bike. About 3 days into riding after putting in these iridiums, out of nowhere i get sputtering and misfire at around 2800 rpm in every gear. Seemed fine in the morning but in the afternoon heat, my bike refuses to run right on anything other than harley-davidson 6R12 plugs. This review is for the DCPR7EIX plugs. Some sportsters run fine on them i have read but my 2011 runs a Delphi system and does not support the ion sensing technology integrated into 6R12's yet the bike ran better than the iridiums which do not have ion sense. Some sportsters may require the DCPR7E which is the non-iridium of the same plug. Tried those, bike was unridable. Switched to Champion RA8HC which is NOT the same as a 6R12, bike ran better but not perfect. I recommend using the stock Harley 6R12 plugs in your sportster.

Good

Have pointed fing tip so be careful with gaping- the fit- they work - as for all the other claims(I.e. fuel conservation- longer lasting- more efficient-) -I have been seeing since copper plus plugs- time will tell

Can't get a better deal on these plugs. Great quality for a great price. Very happy with my purchase.
