Review on Spectre Performance 29516 Blue Split by Rosalio Zavala

I bought these with the intention of using them on spark plug wires. These detachable hoses are undersized leaving a gap of at least 1mm the full length of the spark plug wire. They may not be designed for this, but from what I've read they should have. The next size up looks huge on the connector wires and makes them look awful. I simply rotated the split loom so that the large gap not covered by the loom was on the underside of the connector wire. The plastic felt cheap, wasn't consistently blue, some spots were a little lighter. I also ordered 2 other sizes, which were not so cheap and therefore not transparent, sizes 3/8 and 1/4. I wouldn't recommend them for spark plugs or anything else, I'm sure they're fine.
