Back in the old carby days, these used to go in between the manifold and carby. Do they work with EFI motors? Would it help to put a 1/2 inch one in between the upper and lower?

How much do they sell for?

Remember that carbies flow both fuel and air in a vapor/mist. I can't see how putting a spacer behind your airflow meter would help. If anything, getting the meter closer to the intake would assist in response. Yes?

From my understanding they were primarily to limit or prevent heat soak up into the carby whilst also added marginally to the plenum volume.

Nowadays with cold-air induction systems, modern EFI inlet manifolding and fuel being injected right at the inlet valves I don't think it would achieve much.

They do work on EFI engines. They go between the upper and lower intake manifolds and do two things. Firstly they slow the heat soak to the upper manifold resulting in a cooler intake charge. Secondly they increase the intake length by 1/2" or 1" depending on which one you get, and increases torque. Around 5rwkw increase has been tested on a dyno. Prices are about $175 for the 1/2" or just over $200 for the 1"

if you keep the intake manifold cooler..the air will be cooler..the denser the air ..the more power..
Any type of spacer that reduces heat soak has to be some use ..

Anybody taken any notice of the intake on a gen3?

Does the Gen3 have a spacer?????

I'm wondering if the spacer is good bang for buck?

I have a cold air inlet but it still gets hot (due to the blower), so I was thinking that a spacer will stop the air heating up more and give the motor more torque.

Funnily enough, I was just re-reading a Wheels article on the development of the EL GT engine, they used a 13mm phenolic spacer and Rolf Glenk (the engine developer @ Tickford) said it was worth 1kw and 9nm of torque.

Not sure if I would consider it good bfyb at the prices mentioned by EDXR8.

I assume you have intercooled????

On Gen3 the whole intake manifold is some sort of composite material. Supposedly done to reduce heat soak into the intake charge, more so than for weight saving reasons.
