Well the K&N website is a bit of a joke eh.
Someone needs to sort out all the product codes, none of the codes match descriptions (dimensions, replacement filters etc).
Repco can't find these part numbers and K&N australia has no idea about them either.
Anyway! Can someone please tell me the difference between this
 
56-9070

The point of my post. Will the taller 9075 fit under the hood of a MK1 escort with pinto?
 
Thanks

go to these links - the difference in part numbers seems to come down to whether you want small or large sizes (measurements are included). The the 56-9075 also comes in 45, 54 63 & 83 mm (but different part numbers - 9073, 9074 & 9079)

I know what you mean about Repco - i asked the same thing (ie: here is the part number, please order it). They couldn't believe it was an Oval filter as they only sell round ones (I'm not kidding). No wonder you buy on line

Thanks heaps David. Good to see someone (Burtons) made sense of it all.
The large oval with 83mm high filter will be the go.

Try Amazon for pricing; I think you'll find it is cheaper than the eBay seller.

Hi Flighter
I tried Amazon. $65 but they won't ship to Aus

That's weird, because I checked before posting (and again just now) and they'll ship to me; US$63 + $11 shipping.  That's for the K&N 56-9075.

They'll ship me the smaller 56-9070 too.

I'm after the 56-9079

Ah, that explains it; the cheapest one ships from an affiliate rather than from Amazon itself.  Look to the right of the page and select Amazon as your supplier.  It will cost you an extra $1 but they'll ship it here for a total of about Au$76.  Next cheapest is on eBay USA at about Au $91 delivered.
