Overall, you will find the
four
main types of spark plugs are copper spark plugs, iridium spark plugs, platinum spark plugs, and double platinum spark plugs. Some have better uses than others, depending on the vehicle that you’re driving.
What are the 3 types of spark plug?
- Copper spark plugs. Copper spark plugs have a copper core and use a nickel alloy on the working end of the electrode–the part that generates a spark. …
- Platinum spark plugs. …
- Iridium spark plugs. …
- Pulstar spark plugs. …
- Reducing emissions with every spark plug.
What is the difference between types of spark plugs?
A standard spark plug typically features a nickel-alloy outer material fused to the copper-core electrodes. Copper spark plugs run cooler and provide more power in performance driving situations. … Copper spark plugs are also often used in older (pre-1980s) vehicles with a distributor-based ignition system.
Which type of spark plug is best?
NGK 6619 Iridium IX Spark Plugs
snagged the top pick in our spark plug comparison because they offered the best mix of high-performance, fuel efficiency, durability, and dependability. Featuring an iridium construction, these high-quality spark plugs provide a longer lifespan than copper and platinum spark plugs.
Which is better copper or iridium spark plugs?
Platinum and Iridium plugs
perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat. However, the overall longevity of these two types of metal is better than copper plugs. In reality, copper has the best performance of all three and the worst longevity.
How do I check my spark plugs?
If you don’t have an owner’s manual, or if yours lacks the necessary information, you can find the correct spark plugs and spark plug gap in
a general “Tune-Up Specification Guide”
(called a “spec sheet,” for short) at an auto supply store.
What’s the best spark plugs for horsepower?
- Denso (4504) PK20TT.
- NGK 3403 G-Power.
- ACDelco 41-962.
- NGK Iridium IX.
- ACDelco 9748RR Wires.
Do spark plug brands matter?
Although many motorists and technicians prefer to stick with the same brand when replacing spark plugs,
there’s nothing on the label that limits a particular brand of
plug to a particular vehicle make or model.
Are all spark plugs 5 8?
Most spark plugs require a 5/
8′′ (16mm) size spark
plug socket. This refers to the size of the flats on the spark plug that are in contact with the socket.
Do Iridium spark plugs increase horsepower?
Iridium plugs take less voltage to fire which results in more coil dwell time. That translates to better combustion, lower emissions, better fuel economy and more
horsepower
. Lower your costs. It’s true – buying an upgraded plug does cost more than a basic spark plug.
Which spark plugs are best for fuel economy?
- #1 – NGK G-Power Spark Plugs.
- #2 – NGK Iridium IX Spark Plugs.
- #3 – Bosch Double Platinum Spark Plugs.
- #4 – Denso Platinum TT Spark Plugs.
- #5 – Motorcraft Platinum Spark Plugs.
How do I choose a spark plug heat range?
According to Champion Spark Plugs, for normally aspirated, gasoline-fueled engines, a good rule of thumb is to go about
one heat range colder for each full point in compression ratio increase from 9:1 through about 12.5:1
, and two heat ranges colder for each point increase between 12.5:1 and 14.5:1.
Do iridium spark plugs improve performance?
It has a high melting point, which also means that it can produce great electrodes while retaining its fine characteristics, Iridium spark plugs
gives you better performance
, complete combustion and excellent longevity which makes you free from change your spark plugs frequently.
Can I use copper spark plugs instead of iridium?
If your owner’s manual specifies iridium spark plugs, don’t downgrade to platinum spark plugs,
double platinum spark plugs
or even copper spark plugs. They won’t perform as well as the iridium spark plugs in this case.
Do iridium plugs burn hotter?
Denso Iridium Power plugs feature the heat range at the end of the part number. … Denso plugs
get colder the higher the number, hotter the lower the number
. Starting with part # IK20 (heat range 20), a colder plug would be # IK22, a hotter plug would be # IK16.
