I am looking for suggestions on a quality oil filter for my car. I am not looking for a war, just some suggestions specifically for a hard run SHO Ecoboost twin turbo tuned vehicle. I have decided on Castrol 5w-30 Magnatec with 5000 mile change interval. My manual and the SHO forum highly recommended the MC FL500S, not because of better filtration but because the EcoBoost motor is sensitive to oil filter, non fl500s filters can cause hard or slow cold starts, start up noises and ticks. I believe it has something to do with the "relief valve" and not the filtration. Regardless I want the best this list suggests for my car. Thanks for any help or suggestions.
