High temperature rating?

I do not know, i had a set on my 350 with block huggar headers, tht center header tubes burnt the center plug wires. i had to order a set of tayler wires from Summit to solve this problem.

do you have a set for a 1985 mercruiser 260 350 engine

The universal kit. I received were quite long and are enough to even go under the exhaust..they are a decent buy for the price

How many are in the pack?

10 total. 8 plug wires and 2 coil wires to fit point or hei style coils.

Will this fit a 1995 camaro z28?

will this fit a 2012 camaro ss?
