Does anyone make a throttle body spacer for the G37? Thanks.

 

what's the point of adding a spacer on the throttle body?

 

I thnk it makes some noise, not sure though.

 

i really don't see a point in doing this just for the noise. noise of a air leak?

 

well back in the day.. they used throttle body spacers to increase the volume between the throttle and cylinder, improving volumetric efficiency. similar to plenum spacer.

but I believe modern cars with fuel injections already optimized for standard volumetric efficiency and you'd have to go to forced induction to get any more.

the most you'll probably get is a change in sound..... maybe but there won't be any benefit. but I don't think there is car specific ones out there,, just direct fit cause throttle bodies are kind of off the shelf now a days.

 

no point on the G37 its not like the G35

 

I believe improving the air volume post-tbody may slightly improve the top end power output of the car. This is why everyone was running manifold spacers on the VQ35, except the power improvement was marginal at best.

 

^^^ its done because its cheap and MAY do something. Like BB grounding kit. We really dont know if it does anything but we all buy it haha.

 

The intake manifold spacers are for stopping heat soak not adding more volume as they're usually 1/4t thick at most. I'm not sure it would do anything on our cars as we don't really have throttlebodys per say(not in the traditional sense anyways). The long tube intakes do seem to add more power then the shorty ram airs but that's probably just access to cooler air.

 

I was running plenum and throttle spacers on my maximum (VQ35) and felt gains on the top end but my bottom end (torque) dropped off, which on a V6 that's already lacking torque was kind of disappointing. Not sure on the effect on our engines though.

 

Throttle body spacer is a waste..

 

adding an extra inch or 2 to your throbble body isent going to do anything
