Was thanking about getting a throttle body spacer for my 07 wrangler x good idea bad idea? pros/cons looking for any info i can get do they really help with mpg?

 

Waste of money IMO. Try a search and you'll get tons of threads/posts on it, mostly negative.

 

I had one and threw it on to see what all the commotion was. (I got it free with my CAI)

I tried it with and without the CAI, and tried my best to drive the same as I always do with it. It did NOT change my mileage even in the slightest smidgen (which is what i expected when i installed it). I did notice an ever so slight increase in MPG with the CAI, about 1~2mpg, but that is so slight it is subjective as to whether it was the CAI or not; actually a large possibility that because i was paying so close attention to my own driving habits, that i may have just increased it either way by being more conscious of the throttle.

My personal less than professional evaluation:
It is a really pretty orange lump of aluminum.
Other than it's obvious uses as a paperweight or turn in for scrap, it doesn't do anything.
IMO, Snakeoil.
Don't waste your hard earned money on it.

 

they work on a carburated engine, but not on a engine system like ours. Since the fuel injectors are at the pistons thats where the optimum mixing point is. unlike a carb engine where it is right at the carb.

 

Wasted money.

 

thanks guys looks like ill be saving $100.00 towards something else.
