Air filter

[nelmo]

I want a K&N air filter for my GBS plenum but lots of them. I think this is the right one but can anyone confirm?

Neil, Not knowing the dimensions that you require have a look on their site at:-  https://www.knfilters.co.uk/search/universal

You can then match your needs to the dimensions required.

Yeah, I looked on there but it's not clear what the dimensions refer to - I was hoping someone had bought one for a GBS plenum?

Hi you can buy the correct item from GBS.

Ah, thanks Maca, I didn't see that diagram...

Thanks Blue, I'll check kit spares...

Urgh, great, so GBS suggests their plenum is 85mm but none of the K&N filters are that size. Is Pipercross as good as K&N?
