Do Throttle Body Spacers Work?
Hi Guys!
Well I took it upon myself to test yet another controversial bolt on performance mod: the infamous throttle body spacer! The spacer being tested in this video is an Airaid - Poweraid throttle body spacer. The packaging promises torque, better throttle response, etc....blah blah blah. Anyhow, I got tired of people arguing over whether these spacers actually work. So I spent my hard earned dollars to finally separate fact from fiction. I don't want to spoil the video, BUT.....I can tell you it made +4 torque at the wheels. Check out the results in the video below! Enjoy!

I will also add, that the spacer causes fluctuation in engine idle and after a fill up today, my usual 12.3 mpg dropped to 11.2.

While a throttle body spacer may not work I will mention that one thing I did to my truck that while it's not a performance mod it keeps the throttle body cleaner. I installed a oil catch can on my 4.9l after I had pulled off the throttle body intake and saw how gunked up the inside of it and the throttle body valve were.
I put in a new PCV gasket, PCV valve, catch can ,and bought extra hose (enough to locate the catch can for easy emptying) and some hose clamps to fit everything. Before I installed the catch can I got sea foam in a spray can and with the engine running blasted the inside of the throttle body and cleaned the TBI valve really well. Replace the TBI gasket then installed the catch can and parts.
It catches all the oil vapor and water vapor that comes from the engine and WAS coating the inside of the throttle body gunking it up. Depending on the humidity levels determines how often i empty it. I have never had more than a few ounces of oil/water in it at any time, I check it every time I check the oil in the truck and empty it as needed.
