Here's my latest - I did it at 6K (early) this time b/c I just upgraded to Stage 2 and a larger turbo/downpipe. I'll go 9K this time around.

21K miles, 6K OCI on Liquimoly Leichtlauf High Tech 5W40 w/VW filter (Mahle)

Interesting to note the filtration comments...I run a K&N and opened-up OE intake.

I'll go 9K this go around and see how she goes on the new tune and turbo.

In addition to being a great UOA, you use a bitog coined "rock catcher" K&N air filter? How dare this filter do so well? That's not supposed to be possible.

Enjoy your nice ride and don't change a thing.

Yes, unreal that I haven't seized my motor yet using the K&N...they work just fine if you don't drive in crazy dusty conditions but it's way more fun to debate the minutiae of filtration from "the Spicer report". I use them on all my vehicle.

I believe the spectre of dirt plastering the hot dry DI valves outweighs any perceived advantage.

Explain why every single auto engine manufacturer uses a paper filter... frown

Because it requires maintenance vs. a direct simple replacement....simple as that AND it's a performance piece....why don't manufactures include many of the aftermarket solutions such as catch cans, higher power tune, the list goes on. Performance parts are compromises - performance at the expense of something...engine longevity, emissions, ride quality, and for filters, filtration. The question with high-flow filters has always been to me, does the drop in filtration efficiency (likely ~5%) have any real bearing on the life of your motor AND is the gain in flow worth that? For me, yes (and my UOAs confirm what many say isn't possible...good filtration for my conditions). For others, no. Simple!

There's no reason a disposable air filter can't be manufactured with cotton gauze as the media. "Serviceable" is just a design and marketing objective to get $50 for a filter. An inexpensive gauze filter could be applied to production vehicles just as well, but cotton does not meet mfg specs for media, paper does! Surely a pure race vehicle could afford a new filter after every event. They are not worried about excess wear or deposits anyway. So in my mind K&N is a product looking for a purpose.

Go back to the reason the mfg uses paper, it filters better. What is the primary of a filter anyway.....filtration, not flow. The mfg designs the intake around the flow rates of paper anyway, so what is there to be gained? Sure the perception of more flow sounds good, but really, once flow is adequate....more isn't better. The real difference is the .01hp the engine consumes sucking the air thru paper itself.

Again, your UOA looks good and I intend to reference it when we got our UOAs going.....but it doesn't tell you anything about the dirt flowing onto the dry valves. Not that VW engines are difficult to clean the valves, I just use some CRC GDI every Spring for this. In my case am more concerned about excess wear in the upper cyl and rings. My DD is a Neuspeed 2.0T EA888 Gen2 Valveluft w/40 k that doesn't burn oil. in NO WAY would I risk dirt coming into the intake and wear my rings out. A tiny little part that would be almost undetectable in UOA until it was too late, nope. I doubt you'd disagree.

Understood and your car your choice. I don't worry about it because I don't think I get any more dirt in through the K&N vs. paper under my driving conditions. I plan on dynoing mine soon and will do the obligatory comparison of filters for fun.

I always ran K&N in every VW (6) I owned throughout the years. All of which were tuned to some degree. My 1995 VR6 GTi was nearing 250k miles with Schrick cams, Autotech exhaust and chip tune plus a K&N panel filter, from nearly new. It never consumed oil and was still running strong 3 years after I sold it because everything else was breaking. It's a personal choice.
