K&N marine chrome air filter

I wanted a chrome air filter for my boat and was told the paper elements are not flame retardant (will not pass USCG) so I put on the reusable cotton element. Then K&N came out with a marine unit.

What's the diffrence in the K&N chrome "marine" air filter and a K&N chrome "auto" air filter?

They're both chromed metal and a cotton reusable element.

That's what I thought.

The element isn't paper - It's bimetal with cotton-like batting between the metal mesh.......

So, is there anything inside of the metal lid part or is it flat like the outside?

about $100 bux lol. As pointed out above the marine version uses a different material for the filter that is flame resistant. Same rubber ring design sandwiched inbetween 2 chromed saucers just like the automotive version. I have one on my other boat. Don't count on any performance difference. From what I've seen you need to have a serious engine to get any performance increase. Only reason I did it was my original one got crushed and the K&N was $20 cheaper than the oem one. You could probably get your stocker top piece shined up or chromed for cheaper if that's all you're looking to achieve. Also keep in mind all the ones I came across for my diameter carb were about .5-1" thicker than the stocker, make sure you got enough room under the box.
