"The are the exact plugs that the dealer uses...I have a 2003 corolla...and said no other should be used. We were putting other types of plugs in...what a difference these make in performance and power...gas mileage remains to be seen...just had them changed. (another note...only use dealer ignition coils...or find out what they use...I had to return those)" posted by: Rosey on May 14, 2011 view all 4 reviews
