I don't understand the potential "gap issue." Want to have a set of these plugs to have on hand for my 2013 FXDB. Will this affect me and if so, how?

Others have said that these plugs come pre-gapped, and that is NOT correct. Yes, there is a gap, and if one considers that "pre-gapped," then I suppose they are "pre-gapped" in a manner of speaking. However, it's not as if they come custom-gapped to order, and if the gap is not correct for your bike, you will have to gap the plugs to your bike's required specs. Do NOT use an old-fashioned coin-type gapper. As noted, the electrode tip is very small and fragile, and it can be broken easily, so you will need to gap them very carefully with a wire-type gapper. It's not difficult, but you do have to be careful. If you need help, there are videos all over the Internet. All that said, I do HIGHLY recommend these plugs. My FLSTC runs significantly better with them, and they have also improved my gas mileage by 15-20 percent. I will never buy another spark plug--and I will continue to gap each one carefully to my bike's specs.

They come pre-gapped. Mine had a sleeve over the threaded section that extended to cover the electrode. Pretty fragile in the electrode area that's why gapping is not recommended. My 2008 FLHTCU (Ultra Classic ) runs great on these. Have in excess of 15,000 miles on them.

This quote comes directly from NGK's web site under Tech Support - number 3 - GAPPING.Quote "While it is a popular misconception that plugs are pre-gapped from the factory, the fact remains that the gap must be adjusted for the vehicle that the spark plug is intended for."Check your owners manual for the correct GAP for your bike.-v-

No different vehicles have different type of gap electrode requirements. so check with the dealer

Hi, not quite sure, my question to you is how old is your speaker wire...what gauge..any green anywhere on those conductors..did you do any splices anywhere even the signal wire for a double sub setup has to be done right double check every input jack for wear at the strain reliefs. Hookup one set at time and test at each add

mine are gapped at .45 thousands but I race mine and have a MSD hooked to it a few thousands volts running these in a set of pro comp alum heads. it is a standard plug for normal every day driving. they do make a colder plug but I am at 5000 feet or more so I run these. hope it helps

I had same problem just trim the edges of the connecters and make sure you are putting them in the right polarity positive and negative and frequency wires are in order there tight fit

Probably because they are just meant to be a cross referenced replacement. If you know your stock plug, you find the cross-referenced replacement and it will fit.

I imagine that it could depend on which banana plug you are using but I did not have this problem. Make sure you remove the black and red plugs and that all parts are secure and the connection holes are free from obstructions. My banana plugs do not fit all of the way in, only about 3/4 of the way, is this what you are experiencing? The spring expansion of the plug itself is all that keeps it in place, it does seem a little slipshod but I have never had any problems with sound quality or spontaneous disconnects even though they pull out, easily, with a light tug.

No, there should not be a gap. I would contact the seller and let them what's going on. I would read the reviews and product review before buying any item.

All spark plugs should be gapped according to the manufacterer specifications. Performance is based upon this. Check the manual... It's trivial to do... a 'wire wheel gapper' cost about 5 bucks... well worth it... I bought mine 30 years ago, and have used it for many different plugs.. snowblower, lawnmower, generator.. you name it... (car too!)

I usually never had that problem unless I pushed them too hard, I bought two of these amps, each one pushed a mofo 12" sub. When I got one of them it seemed like something was rattling inside of it, like a peice of metal. Opened it up and sure enough it was. Check the amp, check all your connections, and play with the settings according to your music type. It also varies what your sub or subs your pushing. My best answer is in your connections. See if that helps. Like where your ground is located and how good your ground connection is. But factory defaults do happen, especially if they are cheaply made and mass produced.

Mine sits perfectly, no gap. I'm guessing a batch of their production went bad as i saw some similar comments here lately.

Have your amp checked by a factory installer. Planet Audio is very good at making it right with there customers. I'm sorry but I have never had one do that. So it my be internal.

Surely a connection or the configuration is wrong, they worked well in my car, not sure what's the problem on your truck body, sorry!

Not normal at all. Several issues can cause this, i.e. bad grounding, poor shielding, RFI or EMI from nearby devices/outlets/power wires, faulty amplifier, etc. I personally have 2 F12's and have sold several more to customers and have never had an issue with them.

Front or back it doesn't matter. Some vehicles require an adapter to add aftermarket speakers, as I found out with 2014 tundra dbl cab. if you have question there are a ton of resources available online You don't need to have a dealer install them unless your worried about the warranty.

my 2002 maxima required a 1.1 mm gap - they were close - as I recall 2 of 6 needed minor adjustment

You can check the placement for your car on this site: http://www.ngk.com/product.aspx?zpid=10221 I installed these in my Dodge Ram and did not have to gap the plugs.
