The truck is currently using Autolite XP5245 iridiums. Normally I would go with something from NGK but I figured if the Autolites were a decent price I would get them and they would probably last the life of the truck
If its just painted like some cheap plugs such as some autolites then yes its needed.
I have a stack of 25+ index cards filled with notes about the care and service of the car. The factory service manual has notes and highlighted areas all over it.
Replaced spark plugs with genuine VW Bosch units
So here is my experience with gaps on this engine. The wife 09 Passat was misfiring so I decide to replace the plugs. I buy Autolite double platinums which were gapped huge. Turns out the 0.032 gap was not correct after all and it should have been 0.028. Big difference, this baby flies again (GIAC tune).
Been using bkr7e since 2007. They are ok, but not optimal in any way. Im now running Bosch F5DPOR. \"OEM Audi RS2\" They are gap free, and runs perfect at least at 15psi in my car.
I’ve heard bad things from mechanics about Bosch, specifically Bosch platinum.
the plugs are brand new Bosch Double Platinum.... so then I went out, put them back in and was still a biotch to start....
Don't buy Autolite spark plugs. They suck. I had 2 out of 4 in a pack that were faulty and failed within days of installing them.
I did not have good experiences with Bosch on another vehicle.
