Roadking41a your car should already have some form of WAI.
A thermal element in the air cleaner snorkel that draws heat off the manifold.
Speaking of OEM WAI...I found out yesterday that lots of modern vehicles have it. Read any of the results for this search: http://www.google.com/search?q=throttle+body+bypass
They tell you how to remove it for more power. It's a coolant line that carries hot coolant to the throttle body, and is there supposedly to prevent humidity from condensing and freezing in the throttle body at low temperatures.
How do they compare to a DIY WAI? I'd guess that they don't heat the air as much as we're looking for when we do a DIY WAI.
Typically referred to as a TBB or Throttle Body Bypass... HUGE mod for the F-Body crowd (Camaro/Firebird) equipped with LT1 and LS1 engines. I'm not sure, but the TPI throttle body may have had a coolant line passing through it as well.
I think the level of heat we are talking about is different. only so much heat is going to radiate out of that hose. the exhaust manifold gets really hot and a lot of that is lost in transit to the intake but I am glad it does because I don't want the temps to go nuts on me.
I have heard that if your vehicles computer takes into consideration the temp difference then the WAI will make a difference and if it doesn't then you just lose power because of less oxygen. obviously my car does this because my mileage has gotten better and it has over a long period of time as well.
Be the change you wish to see in the world
