Works as described

Works as any oil filter should. The socket at top should make it a lot easier than the nightmare I had to remove the oem one.

It's a filter

Easy to get the torque setting right due to the nut on the top and i'm sure it filters just fine.

Good looking, functional product

Looks good on bike, easy to clean too. Hex nut makes for easy removal and prevents overtightning. Pretty inexpensive too so couldn't ask for more.

K&N303 R1 2000

A tight fit to get on behind the headers without loosening them, just took a bit of wiggling. Good fit and considerably heavier than the filter that was on, because I had heard that some K & N filters used to split when tightening them up, no problems with this one at all.

K&N is good kit

When is an oil filter, more than an oil filter? When it's a K&N filter. Ok, so maybe that's bit of a stretch, but what can you say about an oil filter really? I like this filter because of the brand, K&N are renowned and because of the nut on top which makes it hella easy to fit and remove. This website offers them cheaper than anywhere else I have found.

Quick & easy

The nut on the end makes life easy. No need to struggle with a strap or chain wrench in a tight spot

Easy fit for clean oil

The KN-303 filter has not presented any oil flow issues and oil remains clear between changes. The hex head makes the filter easy to fit and, with a ring spanner, you can remove it without scalding your fingers! As ever, Sports bike shop is quick, efficient and excellent value.

K&N at there best

Perfect fit, nice addition of the hex on top of the filter to aid fitment/removal over a standard filter. Used K&N in the past on my cars and always found them good.

I use these due to them having a bit on the end which makes removal and installation easier. Good quality and value as expected from a brand like K&N and SBS.
