Dunno what the exact part number for the K&N breather filter is JJ but the filter is 2'' in diameter,has a 1 1/2" filter height,and has a 3/4" flange I.D. Pic 1.
The only breather filter that I can find on the K&N website with those measurements is part number 62-1360.
Breather hose I.D. is obviously 3/4". You're also gonna need an adapter to connect the extension hose to the breather filter. A piece of thick wall PVC pipe with a 3/4" O.D. is one option. Pic 2.
Just a heads-up JJ,TPO Parts sells both the K&N breather filter and the breather hose extension kit which includes an aluminum hose adapter.
