Air Filter vs. Airbox...?

I have an old 94 Katana 750 with low miles. I discovered the air box has warped and will not clamp down over the carbs anymore allowing dirty air straight to the carbs.

I'm considering individual air filters instead of hunting down a new airbox & stock filter. Do I risk any loss in power or fuel economy with individual filters? The bike has after market single pipe exhaust from the original owner so I'm assuming it's been re-jetted once already. I'm not looking for performance, just don't want to lose power or fuel econ.

Any thoughts on individual air filters vs. Airbox would be appreciated. I tried searching the forum for answers but couldn't find any similar articles.

P.S. what are the chances of the 39mm chrome filter pictured below fitting on my 36mm Carb. manifold; they're so much better looking than the sea-green foam ones.

Regards

You will almost certainly have to re-jet things again with this setup.

IIRC, stage 3 jet kits use a setup like that vs. the airbox, so it should work but as Vash said, you will have to re-jet.

I actually had the same problem with my 1991 FZR600, I actually found a solution to still use the airbox. At Home Depot (or any home improvement/hardware store) you can get these rubber boots in the plumbing department for joining pipes easily in low pressure situations. They come with threaded clamps around each end, and you can get them in almost any size, including different sizes on each end. In my case, I had to buy four 2" to 1 1/2" boots, and after cutting them down to the needed length, they clamp nicely over my airbox outputs and my carbs.
