Airaid 450-636 Throttle Body Spacer for Ford Mustang

No vi gran cambio en el consumo de combustible, pero si mejora el sonido del motor y tal vez un poco la respuesta del acelerador, pero no es muy notorio.

Was a little worried that I might not like this because of so many controversial reviews online. I used it with the Airaid CAI and it fits in there with a little work. So far I've noticed a little bit more low end torque. Some of the other mods that I have are just the CAI and a Borla Touring exhaust and with this TBS its really great.

Saw minimal increase in throttle response, but why lie: That whistle is awesome !

I can't use this spacer after purchasing it because right inside the entrance to the stock intake manifold of my 2014 V6, there are 4, 1"x 1" teeth on the top and bottom that are meant to straighten the air flow out. Not only does this completely defeat the air-spinning effect of the spacer, it works counter-productive to smooth air flow because the air is now being spun against essentially a baffle. I don't know if other years have these teeth as well, but there was no warning with the product that says this should be checked for before purchasing the item. I contacted AIRAID and they had no comment. And it didn't look too easy to break the teeth out, as well as make sure no particles break off and go into the manifold. Owell. By the way, in order to use this with a K&N Typhoon CAI with aluminum tube, you will need to cut 3/4" off the tube AND hose connector where it connects to the throttle body in order to make room for it. Many CAIs are different, but regardless, you will need to move the throttle body over by almost an inch so plan accordingly.

Easy to install
