What NGK plug is the same as a champion rc12yc?
Autolite 3923-3926 (maybe more) are listed as equivalent to the Champion and NGK. I had the the exact same Champion RC12YC in my supercharged 360 (Dakota) and then switched to the Autolite 3923 which have a cooler heat range for boosted or sprayed motors. Using that same plug for 10 plus years.
Do all spark plugs come in pregapped?
Nearly all plugs come pre-gapped now. Gapping of plugs was important with the old Kettering (points and condenser) ignition systems, and that has pre-conditioned many, especially us older folks, to think it is important now. With the new high energy ignition systems now in use, plug gap is of little importance, unless grossly out of spec.
Do I have to gap my new spark plugs?
The only reason you should ever need to gap a new set of sparkplugs is if they have been dropped where it bends the side electrode down. As others have said, if a gap is too small it may not start the fire well in the combustion chamber. This only really happens at idle speeds.
Do new spark plugs help gas mileage?
Once your vehicle receives new spark plugs, you’ll notice how much better your car feels while driving. Increased Fuel Economy – Misfiring spark plugs can reduce fuel efficiency by as much as 30%. New plugs that are replaced at regular intervals maximize fuel economy, saving you money. Is 18 MPG good for a car?
What happens if you plug a gap?
Can you adjust the gap on a platinum plug?
Can spark plugs fit different engines?
Should I Gap NGK Iridium plugs?
Iridium Power Gapping Tips In most cases your Iridium Power plugs do not need to be gapped. Even with small variations in the factory set gap the ultra-efficient firing power design will compensate for those small variations.
What do NGK plugs come gapped at?
These plugs are pre-gapped at . 044". Do not adjust gap. Iridium IX - For forced induction (supercharged/turbocharged), we recommend the Iridium IX.
What happens if you don't gap spark plugs correctly?
If the spark plug gap is incorrectly set, it can lead to engine issues. The customer may experience loss of power, misfires, spark plug fouling, increased plug wear, or poor gas mileage.
Do new spark plugs need gaps?
Spark plugs traditionally leave the factory pre-gapped for their most popular application. However, a plug may fit hundreds of engines, from cars to golf carts. Gapping the plugs to your engine's specifications is important to prevent pre-ignition, detonation, fouling and poor fuel economy.
Do NGK Spark plugs need dielectric grease?
Metal shell stretch changes the heat rating of the spark plug and can result in serious engine damage caused by pre-ignition. Do not use anti-seize or lubricant on NGK spark plugs. It is completely unnecessary and can be detrimental.
Are NGK Spark Plugs any good?
Consistently high quality, a comprehensive applications catalog and time-proven performance make NGK an excellent choice for standard electrode and noble metal wire tipped spark plugs.
How accurate does spark plug gap need to be?
The spark plug gap adjustment should not be changed more than 3 times and should not exceed . 008" in either direction. Excessive changing of the spark plug gap setting will result in weakening of the spark plug ground electrode and can lead to breakage.
How important is proper spark plug gap?
Why Is The Spark Plug Gap Important? The spark plug gap influences the heat range of the spark produced to ignite the air fuel mixture in the combustion chamber. This makes it critical to engine performance.
How tight should spark plugs be?
Tighten the spark plug finger-tight until the gasket reaches the cylinder head, then tighten about ½ – ⅔ turn more with a spark plug wrench.
What happens if the gap is too big on a spark plug?
If the spark plug gap in your vehicle is too big, the spark plugs will need a higher voltage to get the ignition spark to cross the gap. The engine can't always provide the extra voltage needed to cross the gap, so the spark is weaker and won't ignite your fuel mixture properly.

Then when you feel resistance you check to see where it is point O five so this one's good now if it wasn't good if you need to make it smaller.
Is a wider spark plug gap better?
A smaller gap will yield a short, intense spark and will usually make the engine real responsive. A wide gap creates a longer spark arc but without sufficient "juice" from your ignition system, (including amps), it can be weak and yellow in color.

How accurate does spark plug gap need to be?
The spark plug gap adjustment should not be changed more than 3 times and should not exceed . 008" in either direction. Excessive changing of the spark plug gap setting will result in weakening of the spark plug ground electrode and can lead to breakage.
What happens if the spark plug gap is too big?
But too much gap increase leading to a large spark plug gap will have diminishing returns. The spark ignition process will draw too much voltage, is inefficient, and if the electrode can't draw sufficient voltage, the spark will get weak and might not ignite the fuel mixture completely.
Can you buy pre gapped spark plugs?
Most spark plug manufacturers will pre-gap their spark plugs for their most popular application but considering that same spark plug might fit over a hundred different vehicles or engines, checking that it matches your vehicle's specifications is a good idea.
Do I need to gap NGK Iridium spark plugs before installing?
yes that is right but mine were all jacked up i had one that had to small of a gap and the rest were to big so i had no choice but to gap it. i had another set before that and i just threw them in with out checking the gap and fouled out the 2nd one not fun but it sounds cool like a suby
Iridium Spark Plugs - to gap or NOT? - Car Talk Community
So it’s time to change the plugs on my 02 Camry 4-cylinger. The owner manual says Denso or NGK Iridium plugs. I nab a four-set of NGK Laser OE spec Iridium Plugs. The o. manual says a .043 gap so I check them with my feeler guage and note they are off - just a tad; I adjust the gap a bit farther being careful not to abrade the electrode surfaces. As I remove the plastic hood covering the ...
How big should the gap between plugs be?
Car measurements differ, and you can thus not use anything that you find on the market. In most cases, the gaps should be in the regions of 0.028 to 0.06 inches. This information is available in your owner’s manual. Where you cannot get it, you can talk to an expert at the auto parts store.
How to tell if 49cc spark plug gap is working?
In this way, you can tell if the 49cc spark plug gap will work for the plug you have in mind. You can now use your tool to adjust the bottom electrode. It should be such that you hold the spark plug with the electrodes facing the floor. From here, you can bend the bottom outward or inward, based on the gap needs.
What does it mean when a tool passes through a gap?
Where the tool passes through the gap and does not touch the electrodes where it should, the gap is too wide. Where the tool cannot fit between the electrodes, the gap needs some widening. If the fit is close to the measurement, you can proceed to install the plug. Do gaps need Denso Iridium spark plugs?
What is the cheapest tool to use to check the efficiency of a gap?
The cheapest tool is the coin-style gap. Here, you run the coin through the gap until you find where it stops. The edge has markings similar to those in a ruler and shows the thickness of the points. You can use this tool when checking the efficiency of the gaps, or widening the gaps as you run the coin.
Why do plugs tan?
It owes to the accumulation of oil and dirt particles around the plug. It occurs due to static electricity released by the plugs. This tan is normal, and you should not have any concerns about it. Some people have mistaken it for broken seals inside the plugs.
How much pressure do you need to bend a plug?
Ensure that you do not bend more than 0.02 fractions of an inch as the plug cannot take much pressure. If you damage the plug, misfires are likely to happen. Where you cannot bend the plug using the tool, you can make the adjustment on a flat surface to add to the pressure.
What is the cheapest tool to use for a gap?
Most tools will have a flat edge, which helps in bending the bottom electrode to help in the adjustment of the gap. The cheapest tool is the coin-style gap.
Why are spark plugs loose?
There are also drawbacks to indexing spark plugs. When washers are added, the spark plug may loosen if the washers don’t crush properly and hold the torque. Also, if too many washers are added, the firing end of the plug will not be as far into the combustion chamber and performance can decrease.
What happens if the ignition gap is too large?
However, if the gap is too large, and the ignition system can’t provide the voltage needed to spark across the gap , or turbulence in the combustion chamber blows out the spark, misfires will occur.
How does indexing work on spark plugs?
Indexing is done by placing (usually copper) washers of varying thickness on the spark plug shoulder, so that when the spark plug is tightened, the plug will rotate a certain amount, and gap will point in the desired direction.
Does spark plug gap size affect voltage?
Since the gap size has a direct effect on the voltage necessary to jump the gap and ionize (light) the air-fuel mixture, careful attention is required. While plugs are pre-gapped from the factory, the gap may need to be adjusted for the vehicle that the spark plug is intended for.
Does the spark plug gap increase performance?
In most engines, performance will improve when the spark plug gap opens toward the intake valve (s). However, without testing different index positions in an engine on a dyno, it is nearly impossible to determine which index increases performance.
What happens if you plug a gap?
The incorrect plug gap for your engine can contribute to a high rate of misfires, loss of power, plug fouling, poor fuel economy and accelerated plug wear.
Can you adjust the gap on a platinum plug?
If adjusting the gap on fine wire or precious metal plugs such as platinum or iridium, be very careful not to apply any pressure or prying force to the fine wire center electrode or insulator as they can be damaged. The gap should be adjusted by only moving the ground electrode.
Can spark plugs fit different engines?
A spark plug part number might fit hundreds of different engines from many different manufacturers. Although the NGK factory will set the gap to a preselected setting, this may not be the right gap for your particular engine.
