Cold Air Intake Tundra

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.

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
