Throttle body spacers

Back to the topic. I'm curious if they're worth it, but unless the cost was low I'd still wait for a after market intake manifold

My bad, never paid much attention to throttlebodies and throttlebody spacers, thought they did the same thing

After doing a quick search; I deduced that TB spacers usually help with engines that are TB injected not multiport injected. Adding a small amount of cfm to the TB wouldnt make a difference as the injectors arent near the TB. For this reason, this is why the BPB's would work better in respect to this option, like @stugray said.

The idea behind a throttle body spacer is to increase the plenum volume.

Check page 8 for a brief description of the effects of changing the plenum volume.

Crawford Performance is proud to announce our latest product, the Billet Power Block (BPB).
CNC machined from Billet 6061 aluminum, our BPB sandwich between the cylinder heads and the intake manifold to create longer intake runners. The lengthened intake runners enhance the volumetric efficiency of the engine which translated into an increase of 19 Horse Power, 15 Pound Feet of Torque and narrowed up the torque dip by 300RPM on a totally stock BRZ. Our BPB also works with any aftermarket tune, exhaust and intake components. Our original road testing was done in conjunction with our stage 1 reflash followed by extensive dyno testing with and without a tune.

well virginia doyou believe?

OK, this is taking about spacers on the intake manifold runners, and the OP was talking about a spacer in the throttle body. Two completely different things. You DO know the difference, right?

I think op is talking about something like this?

then......, install a spacer interesting?

Reading the info on it and trying to figure out how it "creates a better air/fuel mixture"..... Anybody?

Yea I too lack understanding on how it increases manifold vacuum or somehow alters the air fuel ratio or "makes it better." Hypothetically if you left that 1/8" NPT plug open to atmosphere, the vacuum leak would allow un-metered air in and allow a leaner burn for more efficiency?

i was bored on ebay one day and came across very cheap TB spacers for the frs
http://www.ebay.com/itm/281460119020...%3AMEBIDX%3AIT
now, if it does anything or not is an entirely different story, but for $20 atleast it will give you a little bit of color
it obviously isnt going to hurt your car in any way
a quick little google on TB spacers and it comes up with this
http://blog.modbargains.com/throttle-body-spacers/
i did not read it all because well, who has time for that but the part that did stand out was this

'What is a
Plenum Spacer? What is an Intake Manifold Spacer?
Some modern cars, like the
350Z and Scion
FR-S/Subaru BRZ feature a multi-piece intake manifold.
These Plenum spacers are sandwiched between the cylinder heads and the intake
manifold or sections of the intake manifold to create longer intake runners. The
lengthened intake runners enhance the volumetric efficiency of the engine which
translated into an increase in horsepower and torque as well as an improved
power band.


Of course, these
upgrades are a stopgap that offer a portion of the benefits offered by a
performance-oriented Intake Manifold, such as those offered by iPD
Plenum.


So in closing, if
you’re looking for a way to pick up a little extra power and enhance your
efficiency, a Throttle Body Spacer is an effective, inexpensive and
simple-to-install means to achieve that goal.

so who knows. no dynos no one really cares right?
im at the point in my day where i couldnt care less. $20 for at minimum a nice touch of blue to match the rest of the car couldnt hurt, and down the road i now have a plate for WM
