Oil filter Bosch or K&N

I’ve been using K&N air and oil filters in mine for ten years. I run nothing else and will always run K&N. I’m happy with mine. Oil filter number HP1008. I would recommend. The one inch nut on top is often very helpful getting the filter out. I also run K&N oil and air filters in every vehicle I’ve ever owned. There is a noticeable difference in throttle response for the air filter, but I’ve never seen a difference good or bad in the oil filters.

No complaints from my 16 STI running Pennzoil Ultra Platinum and K&N filter.

Yes, the Bosch 3300 is correct for your car. I just used exactly that one for my oil change a few weeks ago.

Brand is personal preference tbh.. ive seen good and bad reviews with royal purple but no evidence that its actually bad. My main 2 that i use are Delo 15W-40 Full Synthetic Heavy Duty Turbo Diesel oil and when thats sold out i run Mobil 1 Full Synthetic 15w-40. And i put a K&N oil filter every time, changing oil at 5K miles and ive had no issues using it as a daily and autocross car. Backroads racing on the weekends, roadtrips, some drifting. Got 271K miles on it and no motor issues.

Have done many oil changes on both my Tellurides, and used K&N every-time, better quality than OEM.

My ‘11 CR-V AWD is sitting pretty at 285,000 miles and I’ve been using a combination of Valvoline MaxLife Engine Oil High Mileage Full Synthetic and K&N High Performance Oil Filter for the last 100k miles.

Valvoline High Mileage w/ K&N Gold filter, I've had no problems, and it runs smooth

I have a 2001 Passat 1.8T, on which the oil and filter have been changed every 6 months or 3K mi, whichever came first. The dealer performed the first 4 oil changes, to the 2-year point, then I took over, always with a Bosch or Napa Gold (Wix) filter. Having received the engine sludge notice, I switched from name-brand dinosaur oil to Mobil 1 at my most recent oil change (last month, 23K miles). Although I receive no adverse temperature or indications at the instrument panel, the valve cover SEEMS perhaps to be running a bit hotter than before. What really concerns me is that, when the engine is warmed up, if I stop and idle it for 30 seconds or so, the engine starts making what to my semi-practiced (but new to VWs!) ear sounds perhaps like valve, lash adjuster, or camshaft bearing clatter. The sound emanates from the rear/cylinder 3-4 area, away from belt-driven accessories, etc. Does this sound like an early symptom of sludge, perhaps associated with insufficient oil pressure at idle? Given my history of frequent oil changes and otherwise by-the-book or better maintenance, I would not have expected to be a sludge victim at 23K miles. I suppose I could have just installed a defective brand-new Bosch filter, or I suppose the synthetic oil could have loosened some sludge from my dinosaur days, but these seem like real stretches for an explanation. Any suggestions regarding diagnostics?

As good as their airfilters are... their oil filters are as shite. They leak and are downright dangerous.

The filter I was running was a K&N. I removed the old filter and it had totally collapsed. The oil light would come on at every stop in the first 10-15 minutes of driving. Especially in cold weather. After changing the old K&N filter that was in horrible condition, I have had no issues whatsoever.
