Cold Air Intake Tundra

[LongArmoftheLaw]

I?m sure with the popularity of K&N products some of you have a fair bit to say about their cold air intakes. Looking to put a cold air intake on a 2020 Tundra. Checked out K&N and have had some buddies put them in their vehicles. I?ve also looked at the manufacturer S&B. Anyone have any experience with S&B or both?

Cold air intakes do not really produce that much more power. You have to be careful with K&N air filters as they are oil soaked and the oil can affect the "Mass Air Flow" sensor. I'd stash the money for maintenance costs of the future. A set of headers will give more bang for the buck. If you really want to make a good investment add a 40000 btu transmission cooler like TruFlo.

FWIW, I do not like wet air filters on 4 stroke motors unless it's a dirtbike. I like paper air filters, they're cheap so you can change them frequently.
I think K&N is a big marketing machine that's convinced people that they can buy an expensive filter and then 'maintain' it with product. Any vehicle built in the last 20-30 years has a well designed engine compartment that's designed to work together. Don't mess with the airbox. It's designed the way it is to keep water out and not compete with the radiator fan.
Wet air filters are for 2 stroke motors.

waste of money IMO. Your Tundra already takes in "cold air" from outside of the engine bay.

Cold air intake is a term that makes me giggle. Is there a refrigerator section under the hood that is storing this air? Does it only work in cooler air temps? K&n is a great product for letting more particulate into your engine.

This is why I stopped using them. Having to buy a special cleaner, oil and then waiting 24 hours for it to dry was a royal PITA. I now change my air filters on both my trucks pretty much every oil change since they are so cheap. Most air intakes from the factory are 'cold air'. Looking at a picture of you the stock airbox on your truck, it appears it pulls air from outside the fender, which would be the coldest air available.



The only time I've used after market air intakes was on high performance diesels. I've used both S&B and K/N and both fit great, but again. those were in high performance diesel applications. Save your money

I put one on my FJ and it made a noticeable and demonstrable increase in acceleration.

It is a dry filter so maintenance is easy.

It is not the "cold air" that makes a difference, it is a much less obstructed path for the airflow.



Stock airbox. Inside it are baffles to quiet the intake noise but they also slow the air as it finds it's way through the labyrinth.




K&N- a single tube and much straighter shot to the throttle body.

Headers work well also. Engines are air pumps. More air in, more air out= more power.

This the third personal vehicle I have done it on.

Oiled filters suck- don't use them, unless you clean them frequently like on a dirtbike. They get clogged and can collapse when the airflow is restricted.

This filter has given me almost 50k trouble free miles and I still enjoy it when I am getting on the freeway.

If you had ?noticeable and demonstrable? performance gains from the air filter setup I?m going to call BS unless you have time slips from Bandimere proving it.

This was my concern about a wet filter…for the price of them and not a great performance increase, the more I’m talking myself out of installing one.

Thank you all for your input, I do appreciate it.
