Oil filter Bosch or K&N

Honestly I just use whatever BMW certified oil I can find at a good price. Used Motul this time, had Castrol before that. Bosch oil filter.

I run Valvoline full synthetic 5w30 high mileage formula with a K&N oil filter.

I use K&N 1008 on my 13, the OEM is slightly higher capacity but I think it affects pressure, and I get a light tick on occasion with OE.

8th and 9th gen Si. I use a KN oil filter. Never had any issues, both cars fully built.

I haven't changed the oil yet on my Civic but I will use a K&N filter when I do. First off it has a K&N intake and I like to use similar/same brands, and also K&N filters come with a nut welded to them which makes them way easier to loosen, no fucking around with a filter wrench needed.

I’ve been using Mobil 1 in everything I have ever had since I first got my drivers license; never had a problem with it yet.

I also religiously use K&N oil filters because they work well, and I like the “wrench off” feature they have.

I get the k&n oil filter since it lasts for 20k miles

So I changed the filter to an $11 Bosch filter, got the car good and warmed up, still low pressure. When I start it up and the oil is still thin, I've got about 50psi and as it warms up it just goes lower until it'S around 10psi at 2000rpm.

I'm perfect fine running this filter at my shop, Bosch can pay for the new engine and my time to put it in and my customer now has an engine with 300k less miles. Thanks bosh for your crappy quality control.

I refuse to buy K&N after one failed and burst apart on my Honda CB1100 a couple of years ago.
