What’s the best spark plugs for horsepower?
The advantages of high-end spark plugs The best spark plugs for horsepower are either made out of platinum or iridium, although spending a little more on iridium spark plugs can turn out to be a better investment in the long run..
Can I drive with a bad spark plug?
A fouled or bad spark plug is a plug that has become covered with a substance like oil, fuel or carbon or one that is blistered from running too hot. Driving with fouled or bad spark plugs can cause a host of problems for your engine. Symptoms of bad spark plugs can include: Reduced gas mileage.
Can you use a feeler gauge to gap spark plugs?
You can use either a feeler gauge or a spark plug gauge to gap your spark plugs.
Do AutoZone spark plugs come pre gapped?
Some brands of spark plugs come ‘pre-gapped’ and require no ‘re-gapping’. For these spark plugs, make sure the tip is not bent or damaged. For other brands and plug types, check the gap to make sure it matches your engines plug gap specification. A gapping gauge tool is available from AutoZone.
Is a wider spark plug gap better?
Many think the larger the gap, the better. 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.
What happens if you don’t gap your spark plugs?
Spark plugs that are not gapped properly will cause the engine to either skip firing, or ignite too soon in the compression stroke. Properly gapped spark plugs also remove heat from the cylinder ignition chamber. The heat range of a spark plug is defined as its ability dissipate heat from the tip.”
Do Iridium spark plugs come pre gapped?
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.
Do NGK Laser Iridium plugs need to be gapped?
They recommend not gapping them because the irridium center electrode is more brittle than most metals and can be fractured or broken.
Can you gap spark plug without tool?
Spark plug gapping is not an easy job to do if the right tool is not there with you. Yes, the gap spark plug tools that are available might feel too extra to buy separately. However, there are some tools that are really great at handling delicate material.
Can spark plug gaps backfire?
Lack of proper ignition system maintenance can cause problems that ultimately lead to backfires. For example, a spark plug gap may widen after the plug has been in operation for months and make it difficult for the spark to jump. Also, carbon buildup may isolate the electrodes, preventing proper combustion.
How does spark plug gap affect performance?
Spark plug gap is a main factor affecting the performance of the engine depending on the engine structure. … A narrow gap leads to weak spark to effectively ignite the fuel-air mixture. On the other hand, a gap that is too wide might prevent a spark from firing at all or may result in misfiring at high speeds.
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.
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 Spark Plugs have iridium center and a platinum ground electrodes.
What should I GAP my spark plugs at?
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 happens if a spark plug gap is too small?
The Spark-Plug Gap If the gap is too small, the spark will likely be too weak and cause the engine to run poorly or with poor efficiency. … A spark-plug gap gauge both measures and adjusts the gap and is inexpensive and simple to use.
Do spark plug gaps increase over time?
it is true though that a wider gap provides a larger flame front for more complete combustion but only to the point of blowout, this gap is usually reduced from factory for increased plug life, since lots of life will be spent at low speed driving and like you said the gap widens over time so the gap is set at factory …
