spark plug boots
by Walter from Goldsbro, North Carolina on September 07, 2014
Boots look good. I haven't installed them yet,but I do have a question about the other end attachment boot. They were not included in my order. Will call you about this.

Is this boot ok for use on a 1994 yamaha 70 TLRS?
It is universal in its and accepts 8mm Universal Spark plug boot. We do not have the original information to confirm your original size. Your OEM number you need is 6G1-82370-21-00.

I need spark plug wire kits for mercury optimax 225 hp 1998?
