NC31 aftermarket air filter options??
Just wondering what air filters everyone is running on their super fours. Looking to swap out a clogged stock one for something a bit better flowing and user serviceable. Eg K&N, Unifilter ect...
Gonna shoot off a email tonight to uni filter to find out what part numbers they have that will fit. If not gonna hit them up about custom making one if there is not one available.
If anyone has part numbers for their chosen brand of aftermarket part them please post it up here and maybe we can make this a sticky for newbies like me!
UPDATE!!! Current part numbers shared:
OEM - HΜ-ΜΥ9-Κ1
HIFLO - HFA1402
K&N - HA-4020

Re: NC31 aftermarket air filter options??
Hi,exept the standard oem ΗΜ-ΜΥ9-Κ1 from Honda that I have used before,I know the ΗIFLO that I use now.
The part number for the HIFLO air filter is HFA1402.I use this because it's very close to the original standards and it 's much cheaper from the oem.I'm not interested in KN because i have heared that the curbs need different sets.

Thanks for that part listing.
No love from Unifilter though.. Kinda disappointing to be honest, want to buy a product from a local company and they don't reply..

Dad's K&N for his Hornet fit with no problem. Didn't use it though, as I didn't want to change the jetting, having a standard exhaust and all.
