Typically the wider you gap your spark plugs the weaker the spark. Usually a spark plug gap +/- . 010 from manufacture spec is ok. However, if you want every last bit of performance from your engine whether you're using platinum or iridium spark plugs, then a proper spark plug gap is preferred..
Also, can you gap platinum plugs?
Do not change the gap on platinum, iridium or twin tip spark plugs, as the fine electrodes may get damaged.
Also Know, do Bosch platinum spark plugs need to be gapped? Yes, Bosch Spark Plugs are pre-gapped at the factory. Note: Bosch OE Fine Wire Series Spark Plugs (Double Iridium, Double Platinum and Platinum) are pre-gapped. Adjustment of gap could cause damage to the center electrode.
Similarly, are NGK platinum plugs pre gapped?
While most NGK spark plugs are pre-gapped, there are instances where the gap requires modification.
What is the proper spark plug gap?
Also, the spark plug gap should never exceed . 055" unless pre-set by the manufacturer. Spark plug gap is where spark plug spark discharge is designed to take place. On a conventional spark plug, it is the area between the center and the ground electrode.

What is the best spark plug gap tool?
Feeler Gauge It's the best tool for measuring and adjusting the spark plug spacing. It's easy to tell the difference in the blade sizes, and you can easily tell which gap size you are setting your plug gap to. Moreover, feeler gauges are inexpensive, and you can easily replace them in case you lose or bend them.Should you GAP new spark plugs?
The gap between the center and side electrodes of a spark plug must be an exact distance; otherwise, your plugs don't fire efficiently. Gap new as well as old spark plugs, even if the package says that the new plugs are “pre-gapped.” To avoid problems, work on only one plug at a time, in cylinder sequence order.Do you gap NGK Laser Iridium plugs?
NGK do not recommend gap adjustment for precious metal spark plugs. A variety of techniques are used to adjust electrode gaps. An appropriate method and tool should be used for gap adjustment although it has come to our attention that a variety of improper methods are used that lead to implications.How do you gap a spark plug with a feeler gauge?
Here's how to gap your new spark plug: - Use a feeler gauge to check the gap of the spark plug.
- Choose the correct wire based on the size of the gap.
- Run the wire between the two electrodes of the spark plug.
- Widen the gap, if necessary, by hooking the gauge on the ground electrode and tugging gently.
Are NGK Iridium pre gapped?
Do I need to gap my NGK IX iridium spark plugs? They come pre-gapped at . 030, which is the gap recommended on NGK's website for the 2.0L WRX (well, for my 2004 anyway).How long do NGK Iridium plugs last?
NGK gives them a life expectancy of 40-50k miles. But they have to temper their projections as driving conditions and motor modifications differ. Typically we have found you can expect 60,000 to 80,000 miles on an unaltered motor. NGK Laser Iridium plugs have iridium center and a platinum ground electrodes.Should you lubricate spark plug threads?
AC spark plugs should be installed dry. Do NOT use any type of anti-seize lubricant on spark plug threads. Anti-seize lubricants decrease the amount of friction between the threads, resulting in over tightening. That can cause the spark plug to move too far into the combustion chamber (in crush washer applications).What happens if spark plug gap is wrong?
Spark plugs that are gapped incorrectly can cause an engine to miss, or run erratically, especially during idle. The incorrect spark plug gaps can cause uneven firing of individual spark plugs and delay engine combustion; both of which can cause an engine to miss or idle erratically.Are NGK V power plugs any good?
NGK Vpower are like $3 a piece and are excellent quality plugs especially for the price. However, the Iridiums are even better. NGK platimum power plugs are an economy plug.Do you gap NGK G Power spark plugs?
Registered. Do not gap them. The platinum tip on these spark plugs are fine enough where it doesn't required to be gapped to produce a fine spark. And where the gap is right now is already designed for optimal performance and life.Should I use anti seize on NGK Spark Plugs?
From NGK - For spark plugs with special metal plating; anti-seize is not recommended during installation. It is recommended to use spark plugs with the special plating on all aluminum cylinder head applications to prevent damage to the cylinder head.How do you tighten spark plugs?
Apply a thin coat of anti-seize compound to the spark plug threads, being careful not to get any near the lower threads. Thread one of the new plugs into the spark plug hole until you can no longer turn it with your fingers, then use a torque wrench to tighten it to the specification listed in your service manual.Should I use anti seize on Bosch spark plugs?
2. For Landfill applications, anti-seize is highly recommended. Bosch recommends Loctite Heavy Duty Metal Free anti-seize part number 51605. When applying anti-seize, only put a small amount at the base of the spark plug as shown.Do you need dielectric grease for spark plugs?
Dielectric grease does not dissolve in most liquids, so it is good for marine and outdoor applications. You can use this grease to lubricate the rubber parts of electrical connectors, spark plug wires, and to protect electrical connections on your boat or recreational vehicle from corrosion.What part of a spark plug is platinum?
A single platinum plug is much like a copper spark plug with a platinum disc welded to the center electrode; a double platinum spark plug has a platinum disc on both the center and side electrodes.What is a platinum spark plug?
A platinum spark plug is similar to a copper spark plug, except that its center electrode has a platinum disc which is welded to its tip area. The copper spark plug only has nickel alloy material in this area. As a result, the platinum spark plug is more durable and can last as many as 100,000 miles.Do you gap Bosch Iridium plugs?
Yes, Bosch Spark Plugs are pre-gapped at the factory. Note: Bosch OE Fine Wire Series Spark Plugs (Double Iridium, Double Platinum and Platinum) are pre-gapped. Adjustment of gap could cause damage to the center electrode.What is double Iridium?
Double Iridium Spark Plugs. The ultra-fine wire design and laser welded tapered ground electrode deliver optimum performance, while the iridium center electrode and ground electrode help it to go the distance. Unlock the performance in your engine with Bosch Double Iridium Spark Plugs.Are Bosch Spark Plugs good?
