Do these spark plugs need to be gapped?

In the kits that I have bought, the plugs were 'correctly' gapped at .040" ... A good habit to get into would be to always check what you receive, just to be on the safe side...Bob B.

I did purchase the RC12YC which are gapped at 0.020" because that is what the manual calls for. The RC14YC supplied in the kit are gapped at 0.040. In retrospect and after doing a bit more research I guess that you can use the RC14YC that come in the kit as is, without a problem. I just prefer to follow the manufacturers recommendation.

As I recall, mine were good....but like Mark says, never hurts to check. You can buy a gauge at AutoZone for a couple of bucks.

Yes, but I found the two in my kit already gapped close enough that I didn't bother. On the test run following maintenance, the generator fired in no time. Take a quick gap measurement, but don't waste too much time trying to get it perfect.

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!)

Always check them against what the manual says they should be; I'd never trust that they were right.

If you have an R/O systems, you will need an air gap. Otherwise, I do not think it is necessary.

That gap is designed to let the air in to mix with the fuel. it is entirely normal. you may have to block it a little in extremely windy conditions.

No sir, go to a muffler shop, have them cut your original cat off and weld the magnaflow cat to replace the gap. That's pretty much what I did. You don't have to mess with your o2 sensor. Now the driver and passenger is a different story.

Yes, it comes pre-gapped from the factory. Do not attempt to gap as it will damage iridium tip. Your vehicle will run like new with these plugs.

I'm sorry I forget what exact socket I used but the spark plug is longer then a standard spark plug so you would need a deep socket. I a 263 piece craftsman mechanic set and I had the socket that fit.

Your owners manual will tell you what plugs your bike will take, if it lists this plug, your good to go(never heard about having to adjust the gap of a new plug). You could always check the gap and make sure it's in spec for your peace of mind. CR8E is stock plug for your bike. Here is a site talking about IX plug, if it's worth it. https://www.ninjette.org/forums/showthread.php?t=46130

Yes they will the 2003 T-bird has a 3.9L F/inj. V-8 DOHC 32 valve engine, and you will need 8 of them and they should be checked to have a .044" Gap. before they are installed, and I believe the Cylinder Heads are Aluminum if they are it is recommended that you use Anti-Seize compound on the Spark Plug Threads other wise there is always a possibility that the Spark Plug threads will come out of the Cylinder Heads when the old Spark Plugs are removed caused by heat corrosion because of the different metals (Steel Spark Plugs/threads),(Aluminum Cylinder Heads/threads).

The coils are plug and play. I changed out my spark plugs at the same time.

no. you need to get the threaded part of the plug out of the head. this is to fix a problem where the threads in the head that hold the spark plug in strip out and have to be re-threaded.

No. There isn't any problem like this they are great. They are just very very little lose in the socket. Flickering depends on your car what you have.

No. Should be pre-set. However, you really should check gap on all plugs you install into an engine. It is good practice, and you can note it as a reference for performance. You may wish to vary the gap based on your requirements for performance, power of engine, and the load you place on it. If you don't know, or have a stock engine, just make sure all the gaps are the same. Use the factory recommend gap, which as we said, should be pre-set. Don't reset it unless you happen to hit the head when installing, requiring a re-check.

They came pre gapped. However I did check just to verify and be on the safe side. I didn't need to make any adjustments.

It was last Fall when i changed the plugs on my '01 Suburban. The new requirement for the 5.3L GM engine is a spark plug gap of .045" vs. the original requirement of .060. I would make them all the same at .040 or .045, which ever is correct. Check through Google. The plugs on my vehicle had never been changed up to 160k miles and what a difference. I think the recommendation is to change them at 100k.

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.

Yes - that's how they are designed with a bit of work. Mine had loose wire connectors at the end of each run to link up the next, so you would need to buy plug connectors similar to the ones that run from the power block at the originating end.
