Spark plug Bosch or OEM FORD

if not oem ACDelco get ones from the likes of ngk, or bosch.

When I had dino burner cars, I did all of my own work, and always used Bosch Platinum plugs for my specific engine and heat. Iridium last the longest life, but are more sensitive to getting hot and causing pinging.

I went with Bosch but you really can't go wrong with the 4 vendors you have listed.

Until I replaced the plugs, coils, alternator, starter, battery and cleaned connections all I could, this problem persisted and my vehicle killed a coil / 2 every season.

Bosch Spark plugs Motul 0W-20 VW oil for the last two oil changes, about 3k miles on the current change AFE air filter Brake fluid flush within last year or so Coolant flush with VW fluid within last year or so Accessory drive belt New belly pan screws and fasteners

So far we have; Changed to new spark plug wires, distributor cap and rotor and the distributor is not leaking oil, tried two different sets of spark plugs Bosch F6DTC and NGK/RIDIUM BKR6EIX.

I ran them for awhile in my Passat VR6.They did decent.Burned really well actually. I think when I was running them I only got about 23 MPG.

Bosch finewires suck dong and AFAIK are not OE for anything even though they claim they're OE for practically every car on the road.

Bosch platinum are trash.

I’ve heard bad things from mechanics about Bosch, specifically Bosch platinum.
