I'm glad you asked this, I have been meaning to talk about it for a while now.
When I fogged my airbox I purchased 3 turbonators (2 7/8"). I put one of them in the fogg tube before the airbox. The second one I put right before the ASC throttle body. The third I placed right before the regular throttle body.
The key with turbonators is to put them at the most restrictive parts of the intake so that they force the air through.
Now, in order to gain maximum hp and mpg, you must make sure to put each turbonator at 90 degrees from the previous ones. I tried 45 degrees but I found that my mpg actually went down but hp was through the roof. 90 degrees is a nice compromise of good hp (about 15 more, 5 for each) and better mpg, best I have gotten so far is 40mpg in the city, and thats with some spirited driving.
Great mod, good luck with the install.
