08 Hummer H3 with the 3.7L In-Line 5.
Has anyone added a TBS or CAIK to this engine?
What is the verdict?
Thanks

A Throttle Body Spacer is a TOTAL waste of money with a multipoint fuel injection system. The whole theory of a spacer is with a carb or TBI it increases plenum under carb/TBI to aid fuel mixing and charging. There is no mixing taking place there with multipoint. On the air cleaner, everyone wants to believe in magic air cleaners but your engines intake is well tuned from factory and well protected against water ingestion too. A cold air kit will throw all that away.

penzfan: Thanks Snoman. Are you a mechanic?
By hobby only. I am semi retired with a engineering background. Been messing with 4x4's longer than most here (over 35 years now) To me it is not if things work but rather how and why things work. (the engineer in me I guess) Because of this, I tend to get a little technical at times.
