S & B COLD AIR INTAKE 6.7 CUMMINS - 5TH GEN CUMMIN 2019-2021 

Sounds a lot more better, turbo sounds a bit louder, runs a bit mire efficient. you get there kit to reapply the oil. I’m about to do mine’s right now and it’s super easy as well. I don’t know if I should do a video on cleaning let me know.

Your engine bay air Temperature no matter the temperature outside is always going to be hotter than the incoming air. The whole point of a turbo charger and cold air intake is to force as much cold air into the engine as possible so it takes less fuel for the air fuel mixture to ignite and create combustion aka power. The colder the incoming air the more power and efficient the turbo works. You removing the blocker plate is making the turbo charger work harder and what you equate to more noise is actually the turbo working more because there’s less available cooler air going into the engine and your making less power and using more fuel to create combustion. You will see a lot of guys putting ice in a chiller or liquid cooling their cold air intake for the turbo who race and want maximum power and wait for temperatures to drop before doing other pulls for the fastest times because again cooler air means more power. You should absolutely install that blocker plate and keep the air filter as clean as possible and properly lubricated with oil for maximum power, also can look into upgrading intercooler, radiator, transmission cooler that will all increase fuel efficiency and boost performance. A tune alone always puts unnecessary wear and tear on parts without the right supporting modifications. Hope this tip helps those that may be less informed with how turbo chargers and combustion engines work and the purpose of cold air intakes etc. cheers 🍻
