Needing to buy a pipercross air filter for a suzuki gsxr 1000 k5 going in an mk indy R.

i Have rung the pipecross shop and they say you can get different heights, wasn very helpful, think i need the px500 with a blank baseplate but there are a few different models of the px500 like the c503d or c504d these are different heights, just wondered which fits either the rounded on ore the more square flat one, cheese for the help

also has anyone used a speedo healer and a x tre is the x tre worth paying £89 to release some more power?

Get a pipercross airbox. It will save you the hassle of fitting one when you have noise problems.
