K&N adapter to S4 air meter

I think I heard somewhere that there is a stock Toyota or Nissan part that bolts to the AFM and has a round end that a K&N filter will mount to.
Can anybody tell me for sure? Anybody have one for sale?

Thanks,
Bruce

Brand new, shipped to your door for $20. Even come with a filter of unknown quality.

My K&N filter/adapter has a larger round part than the one that Chris pointed to. I assume it's a K&N part. I don't know anything about the Toyota or Nissan parts.

Here is a much better design than the ebay one...

The RESpeed piece is a superior part, plus Billy provides excellant service.

My impression was he was wanting to go the cheap route. :) If you want the best part out there check into the carbon fiber ram tube the Spec Miata guys are using.

Thanks Chris. got it. Funny ad though. Just a marketing reseller who doesn't understand squat about what he is selling. Did that before I saw any of the other replies, but yeah, I was most interested in cheap as it is for a rental beginner's car, not a front runner.
