What do U guys think of the 'coolant by-pass mod' on the Throttle body?

I did this and had it like this for 2 years,I can't say I noticed a difference.
I had problems with all of the sensors on the TB and eneded up replacing them all 1 by 1,each time I did the car improved.I way wondering if this mod may have caused heating problems in the TB?
My car has 100,000km on it now.It had 60,000 when I did the mod.
