I am getting better MPG,but It seems a little lacking in the power dept. compared to the autolite copper I had in?!Especially as far as low end torque.
Pros: better MPG
Cons: lacking power, low end torque

Now running the Bosch +2 Platinums and my MPG jumped from about 21 to 25! A lot of others will tell you not to mess w/ the platinums but they are doing well for me.
Pros: improved MPG

Pros: started faster, idled smoother

After too many bad experiences/unhappy motors I wouldn't put bosch plugs in a lawn mower.
Cons: bad experiences, unhappy motors
But otherwise, Bosch FLR8LDCU+.

I bought some of those and didn't think much of them tbh. My engine prefers NGKs for some reason. Feels smoother and more eager to rev. I noticed with the F5DPORs a 'welded on' tip which looked a bit weak
Pros: smoother and eager to rev
Cons: welded on tip weak
Part number: F5DPOR
i changed the original NGK spark plug with new Bosch super 4 spark plugs. a nice improvement but still far from old good performance.
Pros: nice improvement
Cons: far from old performance

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.
Pros: runs perfect at 15psi
Cons: not optimal in any way

Audi
Part number: F5DPOR
As for your plugs, bosch is deff the recommended brand, but just about any high quality plug designed for your engine will work fine. (im currently running platinum in mine, and their fine, but lots of people have reported idel issues with them.) The motor was designed around a copper plug, so thats what it should run on best. so bosch copper is deff the way to go.
Pros: high quality, work fine
Cons: idel issues reported
