Do not change the gap on platinum, iridium or twin tip spark plugs, as the fine electrodes may get damaged.Why do Bosch Spark Plugs say do not Gap?
A spark plugs gap directly affects the tip temperature and the voltage necessary to fire the plug. Bosch spark plugs traditionally leave the factory pre-gapped for their most popular application.Can you gap Bosch Double iridium spark plugs?
Note: Bosch OE Fine Wire Iridium, OE Fine Wire Double Platinum and OE Fine Wire Platinum are pre-gapped adjustment of gap could cause damage to the center electrode.Do you need to Gap double iridium spark plugs?
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.Bosch Spark Plugs - What's the Difference?
What happens if you dont gap your spark plugs?
Q: What Happens If You Don't Gap Spark Plugs? A: Ungapped spark plugs will cause misfires as the gap between the electrodes could be too small or too wide. The air/fuel mixture then may not ignite or ignite on the wrong stroke, which can cause misfires.Are Bosch Double Platinum pre-gapped?
(Note: Bosch OE Fine Wire Iridium, OE Fine Wire Double Platinum, and OE Fine Wire Platinum are pre-gapped from the factory.)Is it OK to Gap iridium spark plugs?
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.Should you check gap on new spark plugs?
Do Spark Plugs Always Have to Be Gapped? Not always. In the past, it was necessary to gap spark plugs, but today spark plugs are usually pre-gapped. It is advisable to double check that the gap is correctly set to the vehicle's recommended setting when installing spark plugs.Can you gap Bosch spark plugs?
Gaps should never by adjusted on Platinum+4 or Platinum2. Bosch Platinum+4 and Platinum2 have factory pre-set gaps, and should never be gapped by the installer. To widen the electrode gap, use a tool that only pulls back the ground electrode, without applying pressure to the center electrode.What is the correct spark plug gap?
For most racing applications, you usually want the plug gap to be between 0.020 and 0.040 of an inch. Most engine builders seem to settle around 0.035 of an inch. Factors such as the type of ignition you run, cylinder heads, fuel and even timing can affect how much gap will work best for you.What is the torque for Bosch Spark Plugs?
1/8 turn on plugs with a tapered seat. E3 - For spark plugs with a gasket: 1/2 turn on 10mm plugs, 3/8-1/2 turn on 12mm plugs, 1/2-3/4 turn on 14mm plugs. 1/16 turn on plugs with a tapered seat.What is double platinum spark plugs?
Platinum spark plugs come in two varieties - single and double 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.Is a bigger spark plug gap better?
The larger the gap, the more voltage is needed to jump the gap. Most experienced tuners know that increasing the gap size increases the spark area exposed to the air-fuel mixture, which maximizes burn efficiency. For this reason, most racers add high-energy ignition systems.How many times can you gap spark plugs?
Repeat the adjustment until the gap tool fits closely between the spark plug electrodes. However, you shouldn't adjust the ground electrode more than 3 times. It's durable, but it's not meant to deal with lots of pressure and might snap off.What happens if spark plug gap is too big?
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.Are NGK iridium plugs pre gapped?
These plugs are pre-gapped at . 044". Do not adjust gap. Iridium IX - For forced induction (supercharged/turbocharged), we recommend the Iridium IX.Are Autolite double platinum spark plugs pre-gapped?
