What are the pipercross like as far as filtration goes?

Also, what sort of oil do you buy Sydney kid for after 10000kms or so?  an how much?

Thanks

ben

Hi Ben, I prefer the Pipercross style with 3 layers of different density foam that are ultrasonically welded (no glue to restrict the flow). They last 3 times longer between cleaning than any single density style. In the Sydney dust and soot we see deterioration after 5,000 ks' in single density filters, regardless of brand.

Pipercross cleaning kits, with both oil and cleaner are available from Fabre.

BTW, 10,000k's is only a guide, I have seen 25,000k's depending on the conditions that the car is driven in.:D

For anyone that thinks K&N and other aftermarket filters are good, this is worth a read.

That test (rather old news) is for a filter for a 6.6 litre diesel truck, you should see the size of the filter. Add that to the engines low rpm airflow requirements.:D

I've seen to many aftermarket filters pass to much dust particles for my likeing, as evidence from the dust stuck to the oil in the intake piping on turbo cars. Makes it easy to show people.

I always run stock elements in my cars, they don't require anything more, and never seen any dust in the inlet tracks. Being cheap i can change them very frequently if i want.

I've seen various testing done that shows the filters are generally not the major restrictions in stock inlet paths anyway.

What i've said may have no relevance to high performance cars though only mildly modified examples.

These pipercross seem like they have a better design principle around them regarding filtration, they are probally preety good.

Will I feel a difference compared to the stock filter.  Car is a R33 Gtst with cat back.  How much are those cleaning/oil kit.

thanks

    • Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!
    • Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.
    • Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 😃
    • You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position. 
    • You talking about the ones in the photo above? I guess that could make sense. Fixed (but flexible) line from the point up above down to the hubcap thingo, with a rotating air seal thingo. Then fixed (but also still likely flexible) line from the "other side" of the transfer in the hub cap thingo up to the valve stem on the rim. A horrible cludge, but something that could be done. I'd bet on the Unimog version being fed through from the back, as part of the axle assembly, without the need for the vulnerable lines out to the sides. It's amazing what you can do when you have an idea that is not quite impossible. Nearly impossible, but not quite.
