nissan genuine oil filter. 15208-h8911au
thats the large one
there is no difference between the large and small oil filters, they are just made to save space, but the small ones would build pressure up more.
I buy filters for my mates GTi-R powered N14 pulsar and my R34 and they both do the same job.
Also, large oil filters are made in thailand and the small ones are made in japan, this also reflects in the cost of them!
