Platinum disc welded to backside of ground electrode provides long life.

However, the most common flaw they do have is wrong gapping. You may need to adjust the gap but it won’t be really time-consuming or costly. The other thing you need to pay attention to is packaging. There are a lot of complaints as for poor packaging. So they can be pretty vulnerable to damage during shipping. Double-check the spark plugs on the spot.

These spark plugs are designed to satisfy all your needs as for improving performance durability. They fire much faster and cleaner with less voltage for easier starts, quicker acceleration and improved fuel economy.

Its full platinum tip assures no gap erosion which leads to longer life span. It is leak proven and heat fused which will guarantee durability and reliability of the plugs. As well as Nickel-plated steel shell is designed for long-life corrosion resistance.

You will benefit greatly with these spark plugs. They will help you with fuel savings and decrease emissions and corrosion. You will spot that the car will start up much quicker and smoother. However, if you come across the misfire issue consider changing not only spark plugs but the ignition coils as well.

In addition, I’d recommend to check the plugs for any oil or coolant leakage. Unless it is stopped, you won’t get rid of a misfire problem.
