Oil filter K&N or Wix

Valvoline all round pretty much with the wix filter, i never plan ahead enough to order the oe filter

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

For the Oil Filter, I would recommend using either the Mazda filter or the Wix/Napa Gold aftermarket, as they are specifically built to meet the Skyactive engine's specifications.

I use Wix oil filter with every change. Decent price and is all metal with a good filter. Does the job and has never failed on me.

For the filter, the OEM is good quality and relatively low price. If you go aftermarket, the Wix filter (also sold as NapaGold) is one of the only ones specifically designed to meet the skyactive specs.

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.

Stick with a Bosch or a Wix and your car will last forever: this is very important now that oil change intervals have gotten much longer.

I'm still running my K&N oil filter, though I've got a Mahle that I ordered along with the ABA pump.

K&N filter is not as good as OE and just about expensive.
