The electronic ignition will not affect the plugs or the gap setting. Use the original recommended plugs and gap.

NEED SPARK PLUG GAP FOR 9BSXS 190-1VH


The gap is .040 and is pretty much a standard gap.

Any opinions on what's better electronic ignition or points .what are the pros and cons to both of any


electronic ignition will beat points hands down any time
to understand this you will need an explanation of how each works.
with a points system there are a set of points , a condenser and a coil
when the points are closed the current flows through the coil windings and produces a field flux
when the points open this field id collapsed and that produces the high voltage for the spark ( understand that current has mass and when the points open the current still flows and that is absorbed in the condenser-- that continuing current flow acts like an arc welder and burns the points )
to make this collapse happen faster the condenser back feeds current through the coil windings and so the voltage is boosted from 12 volts to around 17,000 volts
This relative low voltage induces a high current flow which over a short operating time burns the center electrode of plugs away , requiring frequent plug gap adjustments and plug replacements
problems associated with points include
point gap constantly closing from the wear block being worn away
point bounce at high rpms
coil flux saturation falling off at high rpms reducing the intensity of the spark
water and moisture in the distributor causing loss of spark
on the other hand with electronic ignition there is no points to
get wet
bounce
close up
no condenser to fail
points burn
the electronic system works on a much lower voltage ( 5-7 volts) and a pulse that initiates the action in an electronic circuit that is controlled by transistors and capacitors
This allows for a more rapid increase and decrease in the coil field flux and that increases the voltage to the vicinity of 60,000 volts
this reduces the current across the plug gap and that results in longer plug life and no change in plug gap settings ( EFI systems using quality plugs will never need changing of the plugs from electrode loss)
as electronic systems are sealed there is no problem from water as there is with points , although the same problem remains with moisture in the distributor cap
Now we have a low voltage spark with high current flow to ignite the mixture against a very high voltage with low current flow to do the job
to make it even better some electronic systems will actually continue a series of sparks so that the flame in the mixture is continually being ignited as against the one spark from a points system ( the air fuel mixture is not static but continually rotates -swirls in the combustion chamber)
what does this mean
better economy at higher rpms
better burn rate of the mixture producing power for all of the power stroke
smaller coils
with ECM units that control the ignition , it also controls the ignition timing according to rpms , and throttle setting and mixture setting reducing the need to alter the spark timing for different fuel octane ratings and altitude conditions as it is done automatically to suit the reports from all the sensors
So as I said
electronic system win hands down over points every time

What is gap


Hi, Mike pertaining to engine spark plugs, "GAP" is the distance between the positive and negative electrodes at the base of the plug and is measured in thousands of an inch or mm by using a round pin gap gauge or flat blade feeler gauge. Every engine manufacturer has a specific design-size-heat range- gapped spark plug. Gaps will vary depending on engine brand. Gap is also referred to in engines using a mechanical "POINTS" ignition system instead of electronic ignition (what is the points gap) for more information about your question and valuable "FREE" downloads that you will need please visit the websites below. Good luck and have a nice day.

What is the spark plug gap for a 04 1.6 toyota avensis


Great that you are checking/measuring the spark plug gap...many people overlook this setting...you can not count on the new plug having the correct gap...Most plugs with today's electronic ignitions use the 35 mm gap...however, your best answer is to ask your Auto Parts store what the gap should be when you purchase the new plugs...Good job, hope this helps.

Briggs ans Stratton Quantum 5.5 HP still no spark after changing coil and plug


You are correct, you have a flywheel with magnets in, an electronic ignition unit which when the magnets pass the ignition unit core at speed energises and creates a spark via the plug, the earth wire simply takes the unit to ground and shuts off the spark, the unit you changed was it definetly an electronic unit or just a coil? if electronic and you are cranking the engine fast enough and have the plug well earted against the cylinder with the earth wire not connected it should spark.

What is needed for a tune up?


Thanks for choosing FixYa and welcome. For a tune up, you would need to change spark plugs, coils, distributor cap, coil pack, and wires. You would change the air filter and the fuel filter also. Change your pcv valve as well. You can also change all your fluids and filters, such as oil, coolant fluid, and transmission fluid.

I am seeking the points setting/gap for a 1962 auston 6 cyl 4ltr 2.45ton truck hope you can help thanks gary.


If it still has a breaker point ignition system then gap the spark plugs at .032 inch, or .81 mm, and if the distributor has been converted over to an electronic ignition system then gap the spark plugs at .040 inch, or 1.0 mm.

Replaced coil, spark plugs,plug wires, rotor and rotor cap, and the part under the rotor (forget the name) car has a miss when idleing and when getting on it, NAPA said the spark plug gap should be .035,...


if this is a four cylinder engine,the plug gap is what NAPA told you,verify you have the right plugs and gap,next remove the cap again and verify the plug wires are pulled into cap where they will lock in.

How to replace sparl plugs on a Jeep Cherokee?


Hello, I hope this info helps...(subytech1)...REMOVAL
In this engine, each individual spark plug is located under each ignition coil.

  1. Prior to removing spark plug, spray compressed air around base ofignition coil at cylinder head. This will help prevent foreign materialfrom entering combustion chamber.
  2. On this engine each individual ignition coil must be removedto gain access to each spark plug. Refer to Ignition CoilRemoval/Installation.
  3. Check condition of coil O-ring and replace as necessary.
  1. Inspect spark plug condition. Refer to Spark Plug Conditions.
CLEANING
Theplugs may be cleaned using commercially available spark plug cleaningequipment. After cleaning, file center electrode flat with a smallpoint file or jewelers file before adjusting gap.

CAUTION: Never use a motorized wire wheel brush to clean sparkplugs. Metallic deposits will remain on spark plug insulator and willcause plug misfire.

ADJUSTMENT

Setting Spark Plug Gap - Typical
Check spark plug gap with a gap gauge tool. If the gap is not correct,adjust it by bending ground electrode. Never attempt to adjust gap bybending center electrode.

INSTALLATION

CAUTION: This engine is equipped with copper core groundelectrode spark plugs. They must be replaced with the same type/numberspark plug as the original. If another spark plug is substituted,pre-ignition will result.

Special care should be taken when installing spark plugs into cylinderhead spark plug wells. Be sure plugs do not drop into plug wells asground straps may be bent resulting in a change in plug gap, orelectrodes can be damaged.

Always tighten spark plugs to specified torque. Over tightening cancause distortion resulting in a change in spark plug gap or a crackedporcelain insulator.

  1. Start spark plug into cylinder head by hand to avoid cross threading.
  2. Tighten spark plugs to 27 Nm (20 ft. lbs.) torque.
  3. Before installing coil(s), check condition of coil O-ring andreplace as necessary. To aid in coil installation, apply silicone tocoil O-ring.
  4. Install ignition coil(s). Refer to Ignition Coil Removal/Installation.
