At idle you're talking about 1 cycle/sec per cylinder if I'm mathing correctly... so at 3k rpm you're saying your Wife can detect 3 injector cycles/sec/cylinder.... that's amazing!!.... perhaps my maths are wrong but I'm still skeptical what you think you're hearing is the injectors...
It's only when idling.. You guys don't have to be mean, I know what I mean and what I'm hearing. If you want to answer my question then do it, otherwise go away.
I didn't intend for my comment to be taken as mean, I really meant I was impressed that the wife actually knew what injectors would sound like. Women generally aren't as into cars like guys, my wife knows enough that she would not fall for any crap from a repair shop but I doubt she could discern injector noise.

The bosch 42 units are actually a bit louder than the stock units and regardless of which ones you go with, you can still hear them when inside the car except when making open pulls with an aftermarket exhaust.
