Silly question, but I’ll ask it anyway.

Reverse thought experiment: would the car run better if you used audiophile interconnects in place of the stock spark plug wires? 

I spend most of my time in the future. I only come back here for the jokes. Besides, they don’t have audio forums in the future. The trolls got too out of control. 

They stole it 20 years ago. You should sue.

Then there’s this,

“The Nanofiber main strength is its exceptional midrange purity (we feel the midrange is absolutely as open as with the Indra - the flagship of STEALTH analog interconnects). The Nanofiber offers first class overall presentation: excellent speed, very good midbass and deep bass performance, sweet treble - but this sweet treble is not extended enough to qualify for the reference level - i.e. truly complete with the Indra when it comes to critical listening. However, there is one area where the Nanofiber actually outperforms the Indra: these pure carbon cables offer the least "listening fatigue" of all cables we have ever tested (our own and other brands). In our opinion, the Nanofiber is the best choice for pure listening pleasure - all by itself, or in combination with the Indra or the Metacarbon. If you like the Quad ESL loudspeakers, then you are most likely to prefer the Nanofiber to any other cable.”

One can’t help wondering if the car would run better if the spark plug wires were all in the correct direction. Hmmmmm...

roberjerman is right. Of course, he thinks clothes hangers are fine, too.
