Interesting. I actually installed the pleated top too and I think it feels a little better.

However, my dyno guy said that he doesn't like the pleated top and thought it would be better to try to get a more traditional setup but try to increase size of element to 4" (mine is currently 2+".

By the way, I have also recently been adding about 10-20% of 111 octane race fuel; it feels like a 10-15 hp boost; and it runs so much better.
