Yet another K&N Air Filter setup

I love Hap's K&N filter setup that utilizes the Cooper's backplates and the RU-4410 filters: Elegant simplicity.

A few of my customers have wanted the same simplicity, but a prettier look that also balanced the engine bay a bit better. I really believe that this is the K&N filter set that Peter Burgess refers to in his book. This kind of depth will work with the original Cooper's stubs. All that is needed is to Dremel clearance on the side of the stub flanges to clear the filter mount studs, and one of several different ways to sink the mounting bolts into the stubs. With the cover plates and elements removed, access for balancing and fuel adjustment is simple, and only 2 nuts and lockwashers are removed.

Adam Stockwell granted me levity to put together the SU set and filters for his '68. So I set the filters up as they are on my '68 roadster, and I love the setup. Pics: http://britcarfun.com/images/AdamStockwell/

I think I still like my 4410s, they sure make tuning and maintaining the carbs a lot easier, one twist with a screw driver on each one and the filters come right off.

PS, I am going to send you a message in a second.

Same set up I have on the 72..

I like the fuel line setup.

Jimmy this is the setup you did for me.....similar. I'm happy.

WOW that's Red, I like it.

Here were my HS4s after Hap rebuilt them last year. He is now doing a set of HS6s for me. I sold these to my dad.

What I like about these is that it is all one piece. Undo the bolts to the studs and voila. The custom heat shield is not recommended for street applications. That is why the headers are wrapped.

One more K&N setup

Thanks Jimmy i cant wait to get my hands on the carbs (gloved hands of course!) Now i just need to make my engine look just as good.

Hey David,

You brought one I have not seen or thought about. Any pics of the inside?

There is no backing plate on this setup Jimmy. The filter clamps around the outside rim of the carb horn like Hap's setup.

I also have the exact setup Jimmy described on my '72; it works well. Initially I omitted the Cooper stacks, but after reading about Hap's setup I acquired an old set of backplates and made the necessary mods. The car seems to run noticably better with the stacks. Well worth doing if you've already taken the plunge with the 3.5" K&N's.

Hey Jimmy,

scroll back up to the bright red photo of my engine....


the valve cover has a vent that had a hose going to the cooper cans....

any suggestions what i should do with the vent with this new setup? thanks!

Just get a vent filter they sell at autozone, advance, pepboys, oreillys, etc. It is just a little mesh filter designed to catch the oil as the engine vents.

I use the K&N stub stax inside the 6" round filters.

haven't seen/felt difference between them and nothing (just the flat K&N plate)

Is this a performance gain or a look-cee thing. I'm running the K&N without the stock backing plates but I could put them on if they really improve something?????
