Why do Toyota spark plugs have an you shaped groove?

The name explains the design of this plug — it uses a U-shaped groove in the ground electrode. This u-groove traps the air/fuel mixture before the spark plug fires, making for a large spark, reducing fouling, and making for more efficient combustion. Available for select models, this design has several benefits:

Can a NGK spark plug be used on an outboard motor?

NGK spark plugs are original equipment on many outboard motors and are excellent replacements for everyday engine maintenance. Please view the application guide below. You may also find the NGK spark plug code helpful.

Do you need to replace spark plug wires?

Damage: It’s possible for spark plug wires to be damaged. If the insulation is compromised, or there’s an internal break, you’ll need to replace your wires even if it’s not yet time.

What should I put in my spark plug boot?

That means you’ve properly seated the plug wire. You can put a drop of dielectric grease inside the plug boot for better heat dissipation. Repeat the process in Steps 2 through 7 for each of your remaining spark plugs until you’ve replaced them all.

What can a bad spark plug wire do?

A bad spark plug wires can affect the smooth flow of electrical current which can cause a rough engine idling. Poor fuel economy in a car is a worrisome situation. There could be other reasons like a catalyst issue. But, a bad spark plug wire is a suspect.

Where does the spark plug wire go on a four cylinder engine?

Because every vehicle is different, it is always a good idea — even on four-cylinder engines — to mark the spark plug wire location prior to removing it or to remove the wires one at a time if you are changing the plugs and wires. Obtain the firing order for your vehicle.

Can a spark plug not ignite without a good spark plug?

Well, my response to this question is yes, and that is because the spark plug wires are what makes possible for the spark plug to get the required voltage jolt of electricity from ignition coil in other to ignite the spark plug. So without a good spark plug wires ignition of the plugs will not occur.

Which is the best conductor for spark plugs?

By having separate crimps, the conductor doesn’t need to be bent 180° and get squeezed between the terminal and sleeve. This individual conductor crimp produces a more secure crimp and there is less chance of spark arcing to the engine block or exhaust manifold through the boot! Super Conductor Spark Plug wires are available in either red or black.
