Oil filter Bosch or K&N

I've been running Castrol 5w40 in my cars for years. Started in my '99 Beetle 2.0 and now my 1.8T GTI. I use the K&N filter but I get the one for the Passat since its larger.

oil changed and one new Bosche oil filter later the car now has total oil pressure and runs great.

Been doing it myself with full synthetic and k&n performance filters every 3k ever since.

K&N filters are beefier, my old VRs filters used to come out looking like that. The only filter that would withstand the vr and keep its shape was the k & n

If you are going to go with extended oil changes 10-20k miles you must use a high quality filter and if not a Group 3 Polyalphaolefin (PAO) oil, an actual full synthetic oil would be best. Mobil 1 and Castrol Syntec are not true synthetic they are (PAO) Group 3. Red-Line, Amsoil, and Royal Purple are the common true synthetics. If you paid less than $15-$20 a quart for oil it's not a true synthetic.

Your filter has to be high quality. Even then I would advise you change the filter and top off your oil at 8k-10k miles.

Oil filters that are able to go for extended runs are Wix, Napa Gold, and Bosch. Those are the 3 brands I trust for long term use. My truck with over 170k miles drives like it did over 13 years ago when I got it new.

I use K&N oil filters sometimes, a little cheaper than oem but they are quality.

I ran K&N oil cone filter on a LT1 motor for 3 years in FL and now for 5 years on my 1.8t. Never any problems whatsoever.

Bosch oil filters. I used them to desludge 2 engines, and it CONSTANTLY keeps pulling more and more out. Only problem, they are black, so leak detection can be difficult if its in a tight spot.

Bosch filters are almost as bad a FRAM now.

After much searching and reading DIY threads, I didn't see any mention of springs for the filter. Your replies confirmed it so I was confident enough to throw the Bosch setup in the trash.
