While pulling my air filter today I found that the plastic wire loom on top of the engine is brittle and crumbling exposing the wires. Anybody else have this happen?

Yep, the loom will break down with heat and time. I just replace mine as it crumbles. The clips are more work than I'd like to do to source so I squeeze the new loom through the old clips.

Every one of them under the hood. I replace them with reflective heat resistant stuff. I probably have some more to do now, it's been a while.

I'd agree that crumbling loom is a normal thing over time with the heat exposure in the engine bay. Maybe just a little surprised to see that on a 2014 already. Looms on my 2013 with almost 80k miles seem ok still.

Interesting, of all the cars I've owned over the years I've never had this happen. Is there any reason to leave the giant piece of plastic on top of the engine, airflow routing, hood temp/warping, etc.? If not, this is a perfect excuse to cut in some hood vents and add another electric fan.

mainly just there for looks and protect from some dust IMO.....but it gets dirty under it regardless. I added a PSC hood louver. It doesn't make a hill of beans in regards to cooler engine temps, but I'd guess it helps a little with general engine bay ventilation....some is better than none. I will say the engine cover is nice to deflect rain water that enters through the hood louver. I do recall seeing a couple posts of adding fans to the underside of similar louvers to really push the air out, but seems like a lot of effort for a marginal difference.

Where do you get the reflective wire loom?

My '13 is suffering from crumbling wire loom. I find nylon split loom that's heat resistant to 300 Deg F but none better. Does anyone have a source for a better product? As I don't want to remove connectors I'm going to stick with a split loom instead of a braided sleeve.

Thanks,
