I would go with NGK's or Denso. My rolla (98) had Bosch when I bought it used. I noticed on hard acceleration it would bog down and falter. I never thought plugs would cause that but I spoke with a Toyota mechanic through a mutual friend. The first thing he asked was what kind of plugs are in there? When I said Bosch, he said get NGK's and live happily ever after. . . and I did! It fixed the problem.
NGKs would be my choice. It's affordable and does its job very well.
As for the vibrations, you'd have to tell us when you feel the vibrations and from where ;P
Low RPM's butwhile driving..Dont have a tach so cant be sure...the rear view mirror vibrates like a orbital sander...thanks for the spark plug info..looks like NGK are it...
Denso Platinums are recommended for the plugs.
and if the car vibrates in the pedal and steering wheel at low rpms when in gear (drive, reverse, lows ) then its probably one of your mounts. tranny mount too.
wrong tires for your wheels would cause a noise and vibrations at higher speeds.
check the tread wear. they tell all.
