Odd that it would be short, but Bosch may have just gotten their 
lengths wrong. Nice thing about the OE style sets is that you can 
replace just the wire. Next time you need something else I can throw 
in an appropriate length of wire if you can tell me how much you 
need.

The TVS is NEVER the cause of poor power. I don't know how this got 
started, but for the last couple years it's been getting a lot of 
unwarranted attention. If you think your TVS is bad or unadjusted, 
just unplug it and see if your engine now runs better. If you don't 
notice an improvement reconnect it and move on.

A 5-pin is never an appropriate replacement for a 4-pin. That just 
doesn't work. If you have your original 4-pin it is probably fine. 
I've seen worn out 5-pins, but never a worn out 4-pin.

Of course it's possible that your 4-pin was damaged by someone who 
damaged it internally. That certainly happens, but there's no excuse 
for it.
