I've used HKS RS kit for about a year.

Actually I broke the plastic housing a little bit by tightening the clamp too much while I was installing it.

So the airflow might be leaking though the broken area.

Does it affect the performance of the car? Better to replace the plastic housing as well?

If so, can I just get the housing only without having to buy the whole kit again?

 

mine was buckeld a little bit i know the apexi filter and adapter fits onto the rs intake, other wise the filter cage and adapter are for sale by themselves http://cgi.ebay.com/ebaymotors/EVO-8...QQcmdZViewItem

 

Mine suffered the same damage. the plastic housing/cage is weak.

I'm guessing a simple duct taping would do the trick to seal the affected area?

 

I'll try duct taping first and see how it works to save some buck
Thanks for input, guys!!
