I have the whisper lid and I need the filter for it. Can I just get the one that auto Zone carries or do I need to order it from Thunder Racing?

 

I doubt they are any different. Open it up and see if the one at the store has a gasket for it. I have owned a K&N and a holley power shot, I recommend the holley because it doesn't require the gasket like the K&N.

 

Anyone know if it should have the gasket?

 

Yes, It does. But make sure it's in the box before you buy it.

 

But that one will fit in whisper lid?

 

I got my K & N filter from Auto Zone. Seems to fit ok with the lid.

 

Yup
