Review on 🚀 Enhance Your Truck's Performance with RED 6" Cold Air Intake Cone Replacement- Reusable, Easy to Install! by Brent Peterson

work like these and of course no check engine light! but a gray filter, I personally prefer just oil pre-lubricated K@N or Spectre, N don't clean and re-lube because the factory pre-oil is perfect, no oil can overflow and ruin the mass airflow sensor! So I prefer the annual oil change to the oil change and some say I spend $$ but I will pay more $ and have peace of mind! factual. I also use a pre-filter cap which I would recommend if you use this good one or pre-oiled one! both are a matter of personal preference! Dry first photo separately,,, second Specter with pre-filter cap, but I personally recommend pre-filter cap if still dry! BOTH EXCELLENT! BOTH INCREASE HP! PERIOD! I just prefer the pre-filter cap! LITTLE DUST! we come here
