throttle body space and aftermarket MAF sensor

[snowbrdkid0]

I was recently looking at jet products, and i came across a throttle body spacer and a new MAF sensor. THey claimed to give a little better gas miliage. is this true?

Do a search for throttle body spacers and you'll see the general concensous is that they are pretty good paper weights.

what about the MAF sensor?

IMO i'd skip out on the MAF too.

Both are absolutely useless. The MAF sensor might actually reduce fuel economy if it increases airflow. Your vehicle's ECU will detect the extra airflow and therefore add extra fuel to the mixture in order to keep a proper air-to-fuel ratio. You might get a slight increase in power, but most likely the milelage loss won't be worth it.

 

In most cases, the fuel economy you get from the factory is as good as it gets.

Get you a spacer, a Tornado and a Tubonator and you will be able to keep papers on your desk even in a hurricane.
