He means a direct replacement panel air filter for the stock airbox. And no, not yet as far as I know.

Thanks artood2s i didn't think so i have been searching all over.....i have rejetted with the dyno jet 2193 and the area p full exhaust and it does run a tiny bit rich on the low end and i think a factory drop in replacement filter would do the trick. If i did remove the factory airbox and went with pods would i need to go with a different jet kit??? I did hear it is a pain in the butt to tune with the pods as well??

Done tuning on a dyno with factory pro stage 3 kits and pod filters! mainjet size 112 , needles 3 1/2 - and You wont make more power compared to standard filter and airbox,I say its just a waste of money and fuel!

care to share the dyno charts?
:D Not only that, but 'tuning' an engine doesn't always focus on 'PEAK' horsepower. The less the restriction the faster the throttle response and overall power curve. If I didn't gain 1 hp from removing the box, the other factors definitely (for me) proved worthwhile.

... Yeah and I'd like to see the dyno charts as well. I call BS if HAVING to jump up 10 jet sizes and not gaining any peak horsepower ;)

peak power will be restricted at some point because of VALVETRAIN limitation. unless you change the lift or duration or both for both cams you wont gain any significant power.

honestly...you guys should avoid the K&N filter, like the plague.

there HAS to be something better.
its a piece of crap, as far as an air FILTER goes....

try doing a search...see how they stand up.....not good, i can tell you that.
