NO dyno results yet, but I'm planning on taking dyno readings at some point. I'll post numbers for anyone interested...just not sure how long it will be until that happens. K&N seems to be pretty reliable with numbers, and they will send you dyno results if you call them and ask. They sent me results off a 2000 SE...doesn't help too much since I have an '03, but they were pretty straightforward when I called them and told me what might change the performance improvement you actually can notice. Good luck getting real results...dyno testing is expensive for those of us that don't have connections or our own garage (someday, dammit...someday).
