So I've been browsing around for a drop in filter and so far I'm leaning towards the K&N filters, I recently came across this on Z1
HKS Super Hybrid Air Filters (370Z / G37) What are your thoughts on them? the kit comes with 2 filters for $68 compare as to 46 ea for K&N. Anyone has any thoughts on them? I know HKS makes great quality stuff but thoughts would be helpful.
