Spent some time banging my head against the wall so thought I would post some info here to save someone else the headache.
Kawasaki's OEM spare part (made in Thailand) is: 16097-0009
It's 80mm wide and street cost in the USA is about US$14 or in Australia AU$32 (US$23)
Thought I would see what else was available as I prefer to use an oil filter with a nut on top, easy to torque correctly, easy to remove, easy to race-wire it on the bike too.
K&N have a lookup on their website, the 2015/2016 H2 is listed as a KN-303 and this is where the headache starts. The 303 is the right filter for a Z900RS, Z1000 , ZX10R, ZX14, Ninja 400 and about a million other Kawasaki's including even Jetskis.
It's the equivalent of Kawasaki part: 16097-0008
The KN-303 filter is 65mm wide instead of 80mm wide and while it has the same thread and similar size o-ring (3mm difference in diameter) it's certainly not the same filter.
Kawasaki could have easily used the 16097-0008 but instead developed a filter that is only used on the H2/H2R. The 15mm canister size difference would equal a much bigger surface area of the internal filter and they obviously thought it necessary, unlike K&N who seem to think if it screws in it's okay.
Anyway, I contacted K&N who told me:
The KN-303 & KN-303C is the recommended oil filter for the 2015 Kawasaki ZX1000 Ninja H2R, the oil filter is designed to meet or exceed the OEM specifications.
They weren't interested that the H2/H2R was a different part number and the filter was a different size.
Race Performance (prob an Aussie brand) also make a RP-303 as a 16097-0008 replacement but don't list it for the H2/H2R. It's a good filter on my 900 and my sons 400 but I'm not about to put an undersized filter on the H2.
HifloFiltro do make a specific Ninja H2 / Ninja H2R filter in their "racing" series with 17mm lock-wire drilled nut on top.
What happened to K&N? They used to be a good company. [email protected]
and [email protected]
(both anonymous replies) were totally disinterested in the part number and size difference.
The punchline is HIFLO who also make a 303 filter understand that the spec of the H2 filter might actually be important.
Here's some pics too.
