A sign that says check engine light on we can help | J&H Automotive

Spark plugs should be changed every 30K to 90K depending on the type and your engine. When your spark plugs are old they do not work as well and then your engine does not work as well and it can cause issues from run-ability to poor fuel mileage. 



Give us a call and we can let you know if you're due for new spark plugs.


Happy Adventures,
