Spark Plug Suggestions?
I have a 2002 Ford Focus. What spark plugs are best for my car?
The ones recommended in the owner manual. The correct sparkplug will depend on the model, engine type and in many instances the VIN number
Grassroots used Pulstar plugs on their Focus project.

It was SVT model
The standard factory issue plugs are just fine. High dollar plugs don't work any better.

Use BERU plugs
Hi what ever it is fitted with as you will find out if you try fitting anything others as some do misfire a lot.

Same plugs that came from the factory.
- Would bad spark plug wires cause a check engine light? I just changed the valve cover gasket on my car. Then when I tried to start it, it started violently shaking and the check engine light turned on. The only thing I could think is that maybe the spark plug wires broke when I took them off. Would that cause a check engine light? It's a 2002 Ford Focus ZTS with 150000 miles
- I have a 1976 Ford F150 with a 390 engine. Can anyone tell me what the spark plug gap should be? Don't answer if you don't know. And don't answer if you are just trying to be a wise guy.
- 1999 ford f150 v6 rough idle and spark plug questipn? My 99 Ford f150 is a v6 and I'm having a rough idea or a miss while my foots on the brake and its in gear it idles like it wants to die. I just noticed the 3 plug wired on the passenger side were burnt so I imagine its spark knocking. But my question is what plugs should I use and is this my only problem causing the rough idle? But should I go with e3s?
- On 2002 ford explorer 4.6l the spark plug is drowning in fluid? Happen before on rear cylinder #4 w/ antifreeze from crack in upper intake manifold drowning out the spark plug. So I replaced it, now #2 is doing it, but it seems more like water than antifreeze. It does seem to happen when wet or rainy out. Could it be possible to get that much water up to the top of the engine to settle around my worn out seal for a spark plug boot?
