I recently read a thread where some one was asking about throttle body spacers but today I cannot find it. Also today I saw something on a car show on tv showing a phenolic spacer which is supposed to increase torque and horsepower. Another dream? Possibly. I know that spacers will work on carburetors but I am not sure about efi. Does any-one out there have any info on these spacers? I could use a bit more torque for those long hills.SR
