When I bought my car in the glove box the previous owner had bought 8 spark plugs (the car came with an extra engine) My owners manual lists three different types of plugs. (Hot type or leading - BR7EQ14) (Standard - BR8EQ14) (Cold type or trailing - BR9EQ14) The 8 plugs that came with the car when I bought it were the Standard plugs or BR8EQ14. All eight of them are the same. I was just wondering if it mattered or if I need to buy different plugs for the leading and trailing or if I can just put the standard plugs in all the holes.

thanks

i use the standard br6eq14 in both leading and trailing. no need for 2 different types for each leading and trailing.
