Will changing my air filter to a new style affect the bike?

Hi

I would like to change the standard air filter on my 1998 Suzuki Bandit GSF600. I'm looking at 4 pod/cone style air filters which would attach individually one to each carb, or possibly 2 oval style air filters each accommodating 2 carbs.

Basically the shape/design/function of the air filter would change dramatically and I am wondering how this will affect the running of the bike?

Cheers Thumbs Up

Changing to any kind of free-flowing filter will almost certainly make your bike run leaner. In that case you may need to re-jet the carbs in order to correct the mixture.

You may be able to guess the correct jets, but in my experience (with cars) the only way to get it right is on a rolling road.

Yes. If you go over to pod filters and eliminate the airbox, it'll run like a pig. The airbox plays an important part in helping the engine make power and run smoothly. That odd internal shape and strangely placed plates and baffles aren't just for strength and packaging, they control how the air moves around. Clever engineering involved sound waves and harmonics is involved, and has been since the 80s.

Hi

Bandit airbox is not a great design, but you will need to spend a fair bit of time setting it up if you switch to pid filters.

All the best

Jetted correctly it'll still run worse and make less power than stock.

600's run like shit with pods. Compared to std of course.

To give you a clue, Dynojet only produce a Stage 1 kit for the 600 Bandit. That is for a standard airbox with a K&N and a full exhaust system.

They don't list a Stage 2 or 3 (for pod filters) because the standard airbox with a free flowing filter is enough.

It will absolutely transform the bike, you'll get far more miles per gallon, a huge torque and top speed increase, and any female you ride past will rip off her clothes for you. What are you waiting for, do it!! Thumbs Up

You asked the same question an hour earlier on banditforum, I assume you didn't like the answer you got:

pods = fail

Airbox = good.

I guess it's possible an oil boiler GSXR750 air box might be better... maybe... but you might need different carbs, and modify the tank to accommodate the air box etc.

My advice is don't bother. If you don't follow this advice, then don't come crying to us when your bike runs like a pig.

OK, some good advice on here so thanks for that.

I guessed it wouldn't be as simple as i'd hoped or else why would they have designed such a huge airbox in the first place!

Its a shame as I see a lot of bikes with a pod filter on the carbs and it's a simple but sleek look!

It'll run, but don't expect it to run as well unless you put a fair bit more work into it.

Expect harder starting, and hesitation when opening the throttle as it gulps in more air than it's meant to.

It's fun to muck around with pod filters, but every time I've gone back to the stock airbox, the bike has run better.

I have run pod filters. Pod filters work better on lower power motors or biggish motors with relatively small carbs, like GSX1100s and the like.

Positives:
Easy access to the carbs/cables etc
Sound great

Negatives:
Get wet and the bike runs like shit
The bike will be more sensitive to changes in temperature. Set it up in summer and it will not run right in winter and so on
You generally lose a bit of power low down in the best case and you might lose quite a bit up top depending on the motor and carbs. It can also be peaky and lumpy.
