I had two similar relays that failed on my horn setup (Cadillac 4-note) due to corrosion of pins, so now I run waterproof version.

Skin Effect. Only significant for high frequencies - e.g. at 10k Hz skin depth is ~0.65 mm At motor frequencies, 100-200 Hz max, skin depth is couple milliliters - nothing to worry about.

Almost fairy tale! Man, you're super lucky! I'd still write to NGK, they need to know about this shit.

ECT sensor?

Yeah, looks like it got good reviews from people. Though even at Lowe's price, dollar per pound, it's not that much cheaper than specialized deadening stuff - like 70% or so.

But either way they will break again in couple weeks, right? My goal was to fix it once and for all.

There is some small flow from IM vacuum/boost cycles plus vibrations, so junk can be carried down from EGR tube. 100 thousand words miles:

No boost gains, but it logs twice faster!

Pics are pretty much self explanatory:

Deadening sheets are very heavy and that's their main quality that works. The foam that you linked is completely different animal. It's not my, I wish! :D But I used that thread as my how-to back in 2012 and I like how it worked out and lasted all these years. Foam is used mostly to fight...

While you're at it, I would also suggest to add 3 layers of deadening sheets. I used these ones and they greatly improved street noise isolation...

Anything will be better than oem coffee filters even with all noise our cars make! I have Boston Acoustics Pro60SE (now discontinued), only issue was freezing cones in cold Chicago winters. In general, I'd suggest component speakers that have tweeters mounted separately in doors window corners...

Unlike standard heat range, one step colder NGK's ground electrode is just nickel and not platinum tipped, so they wear faster. NGK specs say 40-50k vs. 80-100k miles longevity. So, for our upgraded cars you can use 50% of these intervals.
