1999 Volkswagen Beetle how to change spark plugs
.040
.028"
Between 0.025 and 0.028 is recommended.
1 - 4 - 3 - 2
They have to be in the firing order.
Some Volkswagen models actually came with a diesel engine. Others have spark plugs located under the distributor cap. Once the distributor cap is removed replace the spark plugs one by one as to not get them crossed.
Takes the spark from the coil and distributes it to each spark plug in the firing order.
The distributor distributes the spark to the spark plugs at the correct time and order.
