will these work well with the Delphi ignition ion sensing? I have read where OEM or NGK are the only ones that will work and all others disable the ion sensing
Trace M on Apr 9, 2017
BEST ANSWER: SPark plugs are simple and after some brief,"brief" research it shouldn't affect thee way the ionization is sensed. But there is a possibility it could affect the driveability. If it does affect it it would set up false misfire codes but seem to run fine and light the service engine light
Are these plugs gaped for harley?
Vinne on Aug 4, 2016
BEST ANSWER: They come fairly close and could be run as is (think they are supposed to come ready to go) but I tweaked mine slightly because all engines require different gaps and the closer you can get it the more efficient the engine will run cause the spark and explosion is what the engine was designed for, so more horse power and better mpg. I have a 1996 Sportster with the 1200cc evolution engine which requires a very large gap from some reason, like twice as much as a lot of bikes. If you can handle putting in spark plugs you can handle properly gapping them, all you gotta do is buy a feeler gauge from any auto parts store and use pliers to open or close them, its supper easy bro. But like I said they come close, in the pair I only had to adjust one of them so I think they are supposed to come ready to rock but you always want to double check that shit, The gauge is like 5 bucks and you can use it for all types of stuff and will take you about 1 minute to do but if you were to take it to the dealership they'd probably charge you 100 dollars and have you bike for half day. haha good luck !!HARLEY LOVE!!
Is this for 1 plug or 2?
A shopper on Dec 27, 2016
BEST ANSWER: It's two plugs for your Motorcycle, as shown in the picture. Find out what your "Gap" is supposed to be, then adjust the plugs accordingly :)
Burnes rich what sparkplug should I use?
A shopper on Jun 18, 2017
BEST ANSWER: I go stock, gap on the larger end. living in Mi I do alot of cold weather riding and read somewhere they help with idle, no noticable difference good or bad with them. Replaced with stock Harley plugs this year and all is good.
I have a 2011 Ultra limited 103 stage 3 ,will These plugs the right choice?
Butch on May 14, 2017
BEST ANSWER: Replace your wires with good silicone ones and should work great. You have to gap these with feeler gauges or you will break the electrode. Been there done that
1998 Harley-Davidson Sportster 883 Hugger that runs rich what should I look at?
Robert L on Jun 18, 2017
BEST ANSWER: Firstly, Is it injected or not. If its a carby model there are a number of things that can cause the problem. If its injected you need to have the ecm checked on a dyno and adjusted accordingly.
