Re: Throttle body Spacer

I cant see how it would help. All that would do is add a half-inch to the plenum volume, which isnt the bad part of a TPI. You would get more gain from a throttle body airfoil.

Re: Throttle body Spacer

actually its probably better than an airfoil because of the swirl... instead of diverting air like an air foil it cyclones it, kinda like the tornado filter... not only would it add plenum volume, but it would increase velocity which would in turn boost top end performance... the weak point in tpi

Re: Throttle body Spacer

waste of money imo. Use your money on other items that are proven to work.

Re: Throttle body Spacer

I had one of these on my car and felt NO difference. All it did was add volume. There was no difference in butt dyno OR real dyno. It is a complete waste of money
