You want lameter air flow not swirls. Swirlies are for toilets. I dont port intakes and ports to get swirls its done to remove them. Swirls cause turblance easly noticed on a flow bench by the noise it makes. Some heads are so loud ya gota go for the ear muffs. Some Yates heads I once did you could bairly hear them flowing air at 360 some CFM.

Could not have said it better my self!

Just thinking back to the "swirl-port" heads on Bill Elliot's T-Bird in the 80s....lol

Different situation there. Ports and valve location and angles produce swirl and tumble in the cylinder/combustion chamber. Piston confguration and chamber shape also come into play. For best power economy and emissions any particular engine requires a certian amount of tumble and swirl. This aggitates the fuel mixture making it as angry volitable as possible. When it is ignited by the spark plug a more complete faster burn is acheeved.

I know that -
my point was how everything old is new again...

In case some of you havent noticed, on your 4.6 heads, there is a built in swirly in the combustion chamber, at the intake valve......so this has already been done, by Ford. No need to tornado anything, or vortex them.

wow, and i bet some of you think subaru's are made in austrailia

Its more like its forgotten every 5 to 10 years. This is what I have seen working for many companies. I could go on about this and how it works and how it actually is and has destroyed american companies and our hold on manufacturing.

"History repeats itself" At least I always seen it that way. It's a matter of how long you can go before it repeats again is usualy the ultimate question.

Has anyone ever installed a Throttle body intake spacer on a 2004 Merc Grand marquis? Did it help any where?

on 5.0's and 5.8 EFI's a phenolic spacer helps a little.

On the PI heads when I port them I remove about half of it. tolittle too much air flow goes south though
