OK Guys, here's a neat item for those who are running a Turkey Pan and wonder whether they're getting enough airflow from their Stellings and Hellings oem aircleaner.

You already know the answer - you are not getting anywhere near enough air into the ol' 427 through the S & H. There are several threads here that have looked at the flow rates - all conclude that there is not enough airflow.

So you do like I did - you start searching the 'net for a suitable replacement. The K & N X-Stream 9" filter nearly always stands out as a possible alternative - that is until you start measuring, and then you see it may not fit.

Until now. Michael has made up a new base to use with a 9" round filter and the X-Stream top assembly. Michael's base lowers the filter over an inch, and provides the needed room under the hood and scoop. In my install, I calculated a nearly 80% increase in surface area by using his base with the 9" X-Stream assembly.

K & N also makes several different 9" diameter filters, ranging from 1"-3" in height, that can be used to customize the X-Stream assembly. Use Michael's base plate, one of the various height 9" filters, and top it off with the 9" X-Stream top, and you have the best flowing filter available for use within the confines of a Turkey Pan.

Thanks, Michael, for taking the time and the initiative to solve this problem for us. The base plate you sent me was nicely made, arrived in great shape, and filled a much-needed niche in the Cobra builders' world. I now have a free-flowing aircleaner for daily driving, and I can drop the old S & H on for shows. A perfect combo!
