K&N Filters

[Ripp3rCrust]

Will be doing a service in the near future on my bike, part of this being replacing the oil and air filter. Is it worth paying a few quid extra for K&N filters or should I just stick with cheaper stock stuff? Is their any particular advantage to the K&N products?

Cheers.

I think k+n pod filters, need setting up on a bandit, and it will never be right, run rough and have flat spots, it's the only thing on a bandit that should be left alone, save your money or better still, spend the money on iridium plugs.

I'd stay with OEM filters, the gain/prize ratio isn't really good if we talk about K&N products and as Ja7 mentioned the bike would need new jets

+You can make your own filter out of the filter foam, I did and it's great the foam for 2 complete air filters costed about 2.50GBP

A friend of mine had CB500 and put in it K&N air filter, tuned exhaust and muffler from Ixil, dynojet kit and some other bits and the bike was a beast BUT the power band was like a stairs

pods arent worth it on a b6, the total surface volume the carbs match the surface volume of the airbox. it is a common thing to do on a b12 due to the extra capacity and larger carbs

I'd definately stick to OEM. I feel that changing the air filter is needlessly introducing potential problems that aren't needed and would cost you money.

Better to concentrate on keeping it running tip top in stock form such as checking the plugs, balancing carbs, valve clearances, oil changes and the likes.

Surely if a filter is letting through more air, it is likely letting through more rubbish too?

Any gains made from a K&N and rejet are going to be marginal and not really worth it.

Don't get me wrong, there's nothing wrong with modding a bike to get more power. Sticking in a K&N without anything else isn't really going to do it though.

Just make sure OEM filter is nice and clean.

K&N oil filter is bit easier to fit, as it has bolt on the top - in my bandit it helps a lot as a filter sits between down pipes.

I had pod filters on the GPz for a bit (partly because I didn't want to fight putting the air box back on), I could never get it to run properly no matter what I done (didn't try rejetting though), eventually I used the heat gun on the airbox and forced it back into place and the bike ran fine again... total waste of money imo

Thanks for the replies everyone, helped me to understand it all a little better. I still have a number of questions though!

I was unaware that it would be possible to fit one of the Pod-style filters to a bandit and will definitely give it a miss anyway now.
However with the flat ones that look similar to the OEM ones, I assume these just slot into place. Would these be compatible without having to do any configuration afterwards (such as rejetting carbs)? If so, do they give any additional performance? After reading on their website it seems that these types also allow additional air in so would this affect how lean it runs?

Another question, how do K&N oil filters differ from OEM ones?

Cheers.

Yeah with K&N filters my bandit wouldnt rev over 5k. Wrapped each filter up with window fabric tape to choke it, and it ran really nicely.

So the prev owner thought they were a good idea (bikes not on the road, and ditching them asap).

As said, I'll be buying those 'pitbike' air filters with duel lots of foam.

Whats the point of putting pod filters on if you can't be bothered rejetting! The whole point of scrapping the airbox and going that route is to gain a little performance isn't it? Surely you aren't going to get that otherwise and will sod up what was an otherwise good running bike?
