Hiflofiltro is the only brand of oil filter we stock at Allmoto and for a good reason - they are pure quality! - See more at: http://www.allmoto-online.com/proddetail.php?prod=HF_Oil_Filters#sthash.jHR9rpSD.dpuf
We've sold others in the past and sometimes had issues with fitment. With the HF range we never have issues with fitment.
They make filters for every dirtbike, racebike, quad and even chrome coated oil filters for the custom bikes like Harleys.
There are generally two types of oil filters available, internal and external. When fitting internal filters or external filters we always suggest smearing a tiny bit of oil around the rubber seal before tightening up the filter.
We also sell oil filter removal tools if needed for external type oil filters - just ask us.
The codes to pick your filter begin with HF. Sometimes if you look at your old filter you will make out the old HF code.
If you're unsure about what filter you need just use the live help or drop us an email. We have a listing in our office for the oil filter code for every motorbike and quad. We'll respond as quickly as possible.
Likewise, if you need advise on the correct oil (standard, semi synthetic, fully synthetic, etc) just ask - we're here to help.
