Cobra oval air cleaner

[kayjayd]

Been thinking about adding one of these to my list of bits to get for my motor.

One thing that strikes me when looking at them is they look a bit restrictive on air flow. Anyone got any views? It'll be going on a SBC stroker with airgap intake and 650cfm Edelbrock carb.

408 cu in stroker Windsor seems very happy with an oval air cleaner, using a 13/4" tall K&N filter element.

About 1.5" wg manifold vacuum at WOT and max rpm - just right.

Tall filter, nice one. Where did you get the filter from Wilf?

Cheers

That is 1 and three-quarters of an inch tall - pretty much the same as the std paper filters that come with the oval air cleaners. K&N do a 3" tall filter as well if you have the headroom - I didn't.
I think I persuaded Demon Tweaks to special order it for me. If you need to know I have the K&N reference at home somewhere, or you can look it up on their site - there is a section with all the shapes and dimensions. E1960 or E1963 from memory. Or something like that.

Thanks Wilf - did a search on those product codes and they seem easy enough to get hold of.

Wilf,Can you please post up a pic of your airfilter???

This is a K&N one that they made to measure. I had to raise the scoop slightly to clear it but it allowed the ram pipes to be fitted inside the filter. Not your set-up I realise but thought the pic might be useful anyway.

Air filter pic as requested.
