Are you supposed to Gap platinum spark plugs?
Do not change the gap on platinum, iridium or twin tip spark plugs, as the fine electrodes may get damaged.
What is the gap on Bosch spark plug for?
Bosch 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.
Does spark plug gap have to be exact?
The gap between the center and side electrodes of a spark plug must be an exact distance; otherwise, your plugs don’t fire efficiently. Adjusting the distance between the two electrodes is called gapping your spark plugs. You need a feeler gauge to gap your spark plugs properly.
Are pre-gapped spark plugs good?
While it is true that many spark plug manufacturers will say that their plugs are indeed pre-gapped, that does not necessarily mean that the plugs are gapped for your specific engine or vehicle. … Therefore, always measure the gap to ensure maximum efficiency and longevity of the plug in your specific engine.
What does increasing spark plug gap do?
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.
Why does my car shake after I changed the spark plugs?
Shaking or vibration may be caused by many different things such as faulty spark plugs, poor fuel pressure or misfires. Other things such as a faulty idle air control valve may cause the engine idle to drop below the normal idling RPM which may also cause the motor to shake or vibrate more than normal.
Are Bosch platinum spark plugs good?
For the vast majority of drivers on the road today, the Bosch Platinum +4 can be considered the best all-around spark plug. … This creates a powerful, long-duration spark which is better suited to igniting the fuel/air mixture in any engine, high performance or not.
What is better platinum or iridium spark plugs?
Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
Do NGK iridium plugs need to be gapped?
In most cases your Iridium Power plugs do not need to be gapped. … Should you decide to re-gap your Iridium Power plug, use extreme caution as improper gapping may damage or destroy the Iridium center electrode or porcelain center.
Are iridium spark plugs worth the money?
Iridium spark plugs give you even better gas mileage, performance, reliability, and longevity than double-platinum plugs. Due to the advanced material and innovative technology integrated into iridium spark plugs, these plugs are priced higher than copper and platinum options.
How often should iridium spark plugs be changed?
Conventional spark plugs should be replaced every 20,000-50,000 miles. Iridium or platinum-tipped spark plugs – also called “long life spark plugs” should be changed 60,000 and 150,000 miles, depending on the owner’s vehicle.
