But blue like this:

I recommend the red. That way it sticks out like a sore thumb...

Where do you get the Blue?

Trident has black, blue and red and possible another color as the different colors are also heat rated. The red is over 500 degrees We used the blue all the time and is way better looking than black.

Trident. also MPI also Shields in that order for quality

Also sell all 3 as a dealer never had a problem with any of them unless from an overheated engine but that would be the boat driver fault not the hose company. Or someone impacted the holding clamps extremely way TOO Tight.

I like the blue.
I wish I had read this 3 MONTH AGO, before I bought 6' of the wire in exhaust hose.
