I am pretty sure most people do not think the Throttle Body Spacers are worth it. First of all, most of these Cold Air Intakes and exhaust systems are for higher RPM gains and I just do not understand why you would restrict them with these restrictive turbulant/turbine spacers.

What about these Mass Air Flow Sensors? These seem to offer even less restriction over the stock honeycomb type sensor and can only help. I guess the concern is if the stock unit is restritive enough to hamper performance on a basic stock engine with only Cold Air Intake and exhaust system?

Nope, none.

I remember remouving the air restricter from the intake on my YJ Sahara. It was quite noticable. The H2 has one of these?
